Hello! Greenhouses and greenhouses help to get a good harvest of crops that are demanding to the growing conditions. Particularly relevant issues are the protection of seedlings and adult plants for regions with a temperate and cold climate. In recent years, greenhouses and hotbeds made of polycarbonate are in high demand, but it is important to choose the right approach so that the design meets expectations and pleases you for many years.

Criterias of choice

Choosing a polycarbonate greenhouse is a crucial step, since the finished product cannot be called cheap, and it is not designed for one year of service.

Today, a wide range of models from well-known manufacturers and firms are ephemeral, represented on the market, so before buying you should carefully evaluate the following parameters of greenhouses and greenhouses:

  • the size and shape of the frame,
  • frame fabrication material
  • type of construction (solid or collapsible),
  • thickness and quality of polycarbonate coating.

The durability of the greenhouse depends on the strength of the frame - the fragile design will not withstand wind and snow loads. The material used to make the base for glazing, as well as the dimensions of the structure, influence the need for arranging the foundation base - a greenhouse with a capital foundation cannot be transferred, but its advantage in reliability.

It is somewhat simpler to choose a polycarbonate greenhouse than a large greenhouse - in greenhouses seedlings are mainly grown, they are smaller in format and the wind load on them is lower. It makes sense to use collapsible greenhouses for growing seedlings in the spring - the rest of the time the structure can be stored unassembled in a shed.

Key features to pay attention

How to choose a good greenhouse from polycarbonate? First of all, pay attention to its frame. The dimensions of the base must comply with the conditions necessary for the cultivation of the planned crops, and the height must be comfortable for work.

Polycarbonate greenhouses are usually made arched - the arch can have a semicircular or lancet shape. The second option is more practical if the greenhouse is not collapsible and is intended for use in a region with snowy winters.

Typically, the material for the manufacture of the frame are plastic pipes or metal profiles - aluminum or galvanized. Plastic arches will not withstand snow loads - this is a cheap option for collapsible greenhouses. The aluminum frame is light and reliable, but the cost of such a greenhouse is much higher. For capital construction, many advise to choose metal profiles from galvanized steel.

Pay attention to the step between the arches. You can not install a greenhouse with large spans - it will not withstand the loads. The more arches - the harder the design. Folding arches do not withstand snow loads poorly, so it is recommended to give preference to solid ones.

The door to the greenhouse should be comfortable and have a secure fit. On the opposite side of the door from the building, a window must be provided, since the building needs to be regularly ventilated to remove excess heat.

One of the key questions is which thickness and which polycarbonate to choose for the greenhouse? Sheet translucent honeycomb material must be at least 4 mm thick. The optimal parameter is 6 - 16 mm - such a material successfully withstands loads even with year-round use. Thicker sheets increase the number of stiffeners, which reduces light transmission ability.

The density of the polycarbonate should be at least 0.7, you must have a quality coating that protects the plastic from UV rays. Preference is to give a greenhouse with a coating of polycarbonate with a special layer that prevents the formation of condensate, but such products are significantly more expensive.

So - note that high-quality greenhouses are equipped with special seals for joints. This increases the cost of production, but the costs will pay off due to the reliability and durability of the structure.

Useful tips

When buying a greenhouse is to give preference to products of well-known manufacturers. It is better to be guided by the reviews of real people, who in practice appreciate the convenience of the design.

Tip: Before buying carefully inspect the greenhouse, set up as a sample. Pay attention to the ratio of the number of arches to the length of the wall, check the rigidity of the structure, evaluate the principle of attachment to the foundation or the ground - if the fixing is unreliable, the heifer will move or overturn the gust of wind.

The galvanized profile must have a sufficient thickness, high-quality protective and decorative layer without damage and signs of corrosion. Check the principle of assembly and reliability of fasteners, the presence of seals and plugs on fasteners for polycarbonate. Conscientiousness of the manufacturer is easy to track by attention to detail. When buying, be sure to check the packaging.

In order not to run into a fake, a polycarbonate greenhouse of a popular brand is better to buy directly from the manufacturer. Choosing the products of local small firms, carefully evaluate the quality of the product.

Which greenhouse is better

Currently there are various greenhouses, differing in various parameters: shape, frame, type of material. The main characteristics when choosing a greenhouse are:

  1. the form,
  2. sizes,
  3. frame,
  4. PVC pipes
  5. manufacturing materials
  6. polycarbonate wall thickness.

One of the most important selection parameters is form. Can find greenhouses of various shapes: pitched, semicircular, arched, rectangular. The most popular and easy to install are arched structures.

Different types of covering material - polycarbonate, film, etc., can be easily fixed on them. soft and light materials, so that the installation of such structures does not require the construction of the foundation.

The disadvantage of such structures is the impossibility of growing plants near the walls. Care of them also presents some difficulties, as the summer resident has to be in an uncomfortable, bent position. Such designs are more suitable. for growing seedlingsthan for year-round cultivation of culture.

The best is rectangular greenhouse. However, a foundation is required for its installation, since due to the use of heavy materials in the construction, the soil under it can subside. Similar difficulties arise in the acquisition of pitched greenhouses.

It must be remembered that without the appropriate skills to make such a greenhouse yourself will not work, better turn to specialists. The most suitable for growing vegetables are arched structures. They are quite functional, and their installation is relatively simple.

Greenhouse size

Do not forget about the size. Choosing a similar structure, it is necessary to take into account the dimensions of the site where it is supposed to be installed. If its area is small, preference should be given a small-sized greenhouse.

It should be borne in mind that it should be spacious in widthso that if necessary it can be increased in length. It will be much more difficult to complete the narrow construction, which will have to be completely rebuilt.

Greenhouses medium size can be attached to the wall of a residential building or commercial building. In this case, free space is saved, as well as materials. Since one of the walls of the structure will be ready, and you will not need to create a strong frame.

The disadvantage of this method of installation is high humidity in the greenhouse, which is why the wall of the building will be constantly damp, which at a comfortable temperature can cause the appearance of fungus, which can later penetrate into the building.

Greenhouses large sizes better to install on large areas. Construction trusses are used for their production, and the installation of such structures on small cottages is impractical.

It is important to choose a quality frame. It can be made of metal, wood or PVC pipes. Each of these materials has a number of advantages and disadvantages.

PVC pipes are selected separately. They are optimal for building a greenhouse, they can be made arched or semicircular. To bend them and drill even the inexperienced builder can.

However, this process in the independent construction is difficult to perform alone, since it is impossible to simultaneously fasten the ends, bend the pipes and watch for the absence of distortions. The advantage of this material is resistance to high humidity, so that this greenhouse will last a very long time.

Covering materials for the greenhouse

We should also choose high-quality materials for the greenhouse. In particular, the following are in demand: aluminum, wood, galvanized steel, covering material.

Pay attention to aluminum. When installing such a structure is necessary to create a foundation. This material is lightweight, with long-term exposure to moisture, it begins to break down. The main advantages are simple installation of elements and low material cost, compared with other types.

Can choose galvanized steel. This material is most suitable for the construction of a greenhouse, as it has the necessary strength and durability. On such a frame, you can fix any coating.

As an alternative proposed tree. This material does not emit harmful substances in the greenhouse, which is very important for vegetables. And its price is quite low, which makes it possible, even with limited finances, to build a greenhouse of medium size.

But this material has several drawbacks. Wooden frame in the construction of need process with special impregnationto prevent its premature destruction from exposure to humid air. In addition, the wooden frame quickly comes into disrepair from the effects of rodents or insects.

It is not recommended to use poisonous liquids to protect it, since they will evaporate inside the structure and enter the soil, which will negatively affect the growth of plants. Be sure to pay attention to the right the choice of covering material. As a rule, various materials are used for this quality:

Most polycarbonate is popularwhich is used to cover medium and large structures. It is lightweight, allows light to penetrate inside the structure and has good strength.

The use of film is more suitable for covering small greenhouses. It is used, as a rule just one season. Since under the influence of precipitation begins to sag and eventually becomes useless. The advantages of this material is a small price and lightness.

Glass as a coating material now rarely used, as it though passes light, but detains warm air. In addition, this material is very dangerous in case of careless handling and requires the construction of a foundation.

How to choose a polycarbonate greenhouse

Choosing a greenhouse with a coating of polycarbonate, you need to know its distinctive features by which it will be possible to determine its quality. Today this material is very popular among summer residents, which has led to the emergence of a large number of counterfeit products.

To determine the quality of the material, you need to pay attention to such nuances:

  • the availability of the necessary documents, which must be specified characteristics sheet, as well as information about the manufacturer,
  • the presence of a mark on the packaging film on the application of a protective layer against UV rays. An additional guarantee of quality is a duplicate mark on the side of the sheet,
  • appearance of the material. It should not have irregularities on the top and inside the honeycomb. In this case, the panels should be transparent, and when visually inspected the sunlight should be visible protective layer, which manifests itself in the form of a fluorescent glow.

Tips for choosing panel thickness

Also important is the thickness of the panels. There are three types of panels in thickness, which are considered the most popular:

  1. four millimeters. It is used for greenhouses installed in suburban areas and used for personal needs. This material has good flexibility, is quite reliable, but easily penetrates with medium-sized hailstones,
  2. six millimeters. Such polycarbonate is the optimal solution. It is not damaged by hail, on its surface only small marks remain. The bottom layer does not touch,
  3. eight millimeters. Such a coating can withstand almost any atmospheric phenomena, but as a coating of small greenhouses it is used extremely rarely. The main problem is the higher cost.

Choosing polycarbonate, you should not save. Then he will serve at least 7 or 9 years. The greenhouse itself must necessarily meet the requirements quality, reliability, functionality, resistance to wear. We should also pay attention to the appearance of the product, so that the design harmoniously fits into the overall design of the garden or the local area.

Polycarbonate greenhouses: how to choose

Many gardeners already use greenhouses made of polycarbonate. This material quickly gained popularity and consumer confidence. With proper treatment, it can serve for many years.

Most importantly, polycarbonate can hold heat well. It performs this function due to its cellular structure.

There is air in the comb, which allows the material not to let the cold air into the greenhouse and not to release warm air. Also, the material is treated with special varnished products that will not allow ultraviolet light to get inside the room. Flexibility and plasticity of the material ensures easy installation of the greenhouse.

The advantages of polycarbonate:

  • Durability. The material can serve faithfully for more than 20 years.
  • Variability. The price of the greenhouse is determined by the characteristics of the material from which it is made.
  • Light transmittance. Gives the chance to a sunlight to get as much as possible into the greenhouse.
  • Sustainability. Varies depending on the density of the material. But at the same time, each species is resistant to mechanical damage. Also, the material perfectly protects against moisture penetration.

Correctly choose a greenhouse can, knowing the selection criteria. A good greenhouse is distinguished from a poor material density and its ability to transmit light and not to pass water. Today the market has a large selection of polycarbonate greenhouses, which differ in characteristics and price category.

What is the best greenhouse polycarbonate

The shape, size and materials of production for greenhouses can be very different. It is important to know which design to choose. This may be galvanized cold rolled steel. It may be in the form of a profile or carrier pipe.

The simplest type of greenhouse is considered - unheated. It is used for growing early crops to harvest before the onset of cold weather.

A variety of types of greenhouses allow you to choose a suitable and affordable option. The most common greenhouses combine options of good quality and price. Overview of greenhouses with different characteristics can be found on the Internet on specialized sites.

What designs to choose:

  1. With vertical walls. Popular type of greenhouses. The design is convenient and allows the use of additional shelves. These greenhouses are characterized by gable roofs. The width and height of the greenhouse makes it easy to use. The disadvantage is the possible loss of heat from the north.
  2. Pointed arch. The greenhouse has a large area, but relatively low ceiling. The installation of such a greenhouse is done by professionals.
  3. Sloping walls. A greenhouse combines the qualities of the two previous greenhouses. It is quite convenient if you do not overload the space with additional shelves and racks.
  4. Mansard roof. Comfortable greenhouse with high roof. It is convenient to place additional devices for growing plants in it.
  5. Arched type. Robust construction is easy to install and use.

Before buying and installing a greenhouse, every future owner can make a rating among those species that he liked the most. It is also important to consider the cost of the greenhouse and its installation options. Some constructions can be mounted only with the help of a professional master.

Low cost polycarbonate greenhouses

Many gardeners ask the question: “What polycarbonate greenhouses to choose so that they are inexpensive and of high quality?” Polycarbonate itself has an acceptable cost. In 2017, manufacturers offer consumers a large selection of polycarbonate greenhouses at a very affordable price.

Any kind of polycarbonate is characterized by durability, impact resistance, flexibility, low thermal conductivity, durability.

The cost of the greenhouse will increase depending on the quality of polycarbonate it is made. In this case, the cost is influenced, for example, by the presence of a protective layer from the sun. Также на стоимость влияет цвет покрытия: оно может быть желтого или красного цвета. Считается, что эти цвет лучше влияют на рост растений.

Преимущества материала:

  • Недорогая стоимость,
  • Большой выбор,
  • Высокое качество,
  • Износостойкость,
  • Гибкость,
  • Plastic,
  • Thermal insulation.

An inexpensive greenhouse or greenhouse can be purchased online. The smaller the area of ​​the greenhouse, the cheaper it will cost. But it is not necessary to buy greenhouses too small in size, they will not allow to get a high-quality and full-fledged harvest. In 2017, producers throw gardeners with profitable promotions and offers.

Reviews of polycarbonate greenhouses

Quality material is always popular. Polycarbonate greenhouses do not lose their popularity among consumers. They are the most common type of greenhouses, which are successfully sold throughout the country.

Samples and examples of polycarbonate greenhouses can be found in the catalogs of different manufacturers, as well as on the websites of companies that produce and sell greenhouses.

Last year, polycarbonate greenhouses ranked first in sales. This means that greenhouse owners are happy with their purchases. After all, the durability of such greenhouses far exceeds, for example, the service life of film greenhouses.

What do owners like:

  • Affordable price,
  • Easy to install
  • Moisture resistance
  • Sun protection,
  • Strength,
  • Reliability,
  • Durability.

Positive quality greenhouses can be listed for a long time. Every owner knows that in many respects the service life of the product depends on proper handling. Before winter, after harvest. The greenhouse needs to be well cleaned and prepared for the following crops.

The service life of polycarbonate on the greenhouse: reviews

In many ways, the service life of the material depends on who uses it and how. Also, the durability of the greenhouse is affected by the fact that the company has manufactured the product, as well as the quality guarantees it has given to it. Different models have different service life - it depends on the quality of the material.

Greenhouses for the Urals, Severnaya and Kinovskaya - all these greenhouses are intended for use in their latitudes. Improper use may lead to its unsuitability.

To choose a greenhouse you need to responsibly. You should not save on cheap materials, since any investment will pay off over time. A good greenhouse can last more than 20 years.

Greenhouse Care Tips:

  • Replace broken and damaged parts in time.
  • Correctly adjust the pressure of the thermo washer.
  • Thoroughly clean the cavities of the panels.
  • Systematically wash the surface.

It is important to care for the design all year round, but especially in the fall, after picking the fruit, and in the spring - when planting. To wash the greenhouse, you can use any detergent. It is only necessary to wash the surfaces with soft sponges, as hard brushes can damage the surface.

The best polycarbonate greenhouses

When choosing a design for a greenhouse, every summer resident should pay attention not to the quality of the material from which it is made. It is important to be able to correctly identify the advantages of the greenhouse and highlight its disadvantages. To do this, you need to study the sites that offer polycarbonate greenhouses, be able to compare different designs.

A quality greenhouse must be so strong as to withstand large amounts of snow.

If the greenhouse is made of thin and poor-quality material, the snow may well break through or deform the roof. Replacing the old coating will be expensive, so it is better to spend enough money right away and get a quality construction. When choosing a greenhouse, it is important to determine what characteristics will be optimal for installation and use in a particular region.

What are the best greenhouses:

  • Durable,
  • Durable
  • Reliable,
  • Wearproof,
  • Waterproof,
  • UV resistant,
  • Easy to install.

Polycarbonate greenhouses for giving are considered the best. These are durable greenhouses that guarantee a long service life. The best greenhouses should be produced by a well-known manufacturer who can be trusted, who is ready to provide a certificate of quality and warranty service life of the product. Gardeners themselves can extend the life of the greenhouse by its proper operation and careful maintenance. When buying a greenhouse, it is important to take seriously its delivery and build quality - it is impossible to damage materials before the start of the greenhouse's operational period.

Galvanized bent profile

Galvanized steel profile is lightweight and affordable price. Moreover, its mechanical strength is clearly insufficient, which is compensated by the use of a larger number of elements. Connections between the individual parts of the frame need additional reinforcement. Often, such a framework consists of many joints, and the thickness of the metal is only 0.5–0.8 mm, which is clearly not enough to withstand peak wind and snow loads.

Galvanized bent profile

Galvanized profile frame

Steel profile of rectangular or square section

The supporting frame, welded from a steel pipe of rectangular section, is distinguished by its durability, high resistance to constant and variable mechanical loads. The main disadvantage of it is the tendency to corrosion and the need to protect parts from rust. The frame of the greenhouse is quite difficult to manufacture, which determines the high cost. The arcs of such greenhouses consist of only a few elements, and can be generally integral.

Steel square profile

Greenhouse frame made of steel profile

The choice of material for the construction of the frame is based on the requirements and capabilities of the customer. If you are going to purchase a finished greenhouse, then most likely you will be offered a frame on a thin-walled profile, less often there may be a frame from a profile of rectangular or square section. The best option for strength is a frame of profiles of rectangular or square cross section. The framework of a thin-walled profile will be less durable, but much cheaper and there is a high probability of running into low-quality manufacturers, which, in order to save, make the framework not sufficiently rigid.

However, this does not mean that you should abandon this framework. Just before purchasing such a greenhouse, you need to make sure that it is really durable, and the thickness of the metal is at least 1.2 mm. As a rule, each seller has samples of frames, you just need not be lazy to come and carefully consider the available options. If the seller in every possible way hides and does not show samples of frames there is a high probability that you will be sold a low-quality product.

When choosing a frame, also pay attention to the following points:

  • How many elements consist of an arc, it is ideal that they are all-concave.
  • It is best if the frame profile has a rectangular section of 20 × 40 mm, this is especially true for the base of the greenhouse, because if it is made of a profile with a section of 20 × 20, this may not be enough.
  • The thickness of the metal must be at least 1.2 mm., Otherwise there is a big risk that the greenhouse will not last long.

Type of polycarbonate

Today there are two types of polycarbonate on the market - cellular and monolithic. Among these materials, cellular polycarbonate has the best characteristics for use as the roofing material of the greenhouse.


Cellular polycarbonate is a sheet material from the group of thermoplastics, consisting of two or more layers with longitudinal internal bridges. This structure of the plate provides excellent technical characteristics and operational properties of the material.

The most significant of them during the construction of the greenhouse are the following:

Low specific weight

High thermal resistance

High light transmission

High flexibility

Resistance to climatic conditions

High mechanical strength

Technical characteristics that are important for deciding on the choice of polycarbonate cellular for the construction of the greenhouse are presented in the table:

The presence of a light stabilizing layer

High-quality cellular polycarbonate has excellent light-transmitting characteristics of a selective nature. It almost completely absorbs ultraviolet radiation with a wavelength of 400 nm or less, is the most dangerous for plants and transmits the rays of the visible and infrared range as much as possible. It helps to create a greenhouse effect.

To protect the cellular polycarbonate from the destructive effect of ultraviolet radiation on its outer surface, a layer of light-stabilizing substance is applied by coextrusion. To find out about the presence of such a protective coating can be on the appropriate inscriptions on the protective film, glued to the sheet of polycarbonate. Here you need to be attentive. If there are no special marks on the protective film, this means that they are designed for indoor use.

An attempt to use such materials for the manufacture of greenhouses will lead to premature failure of the coating. One of the most important properties of polycarbonate is the ability to maintain its technical characteristics throughout the entire service life of the panels. Some manufacturers claim that UV protection is in the mass of material. In fact, it is not enough and it is intended only to prevent the destruction of the material during storage.

Polycarbonate thickness

When choosing a cellular polycarbonate for the construction of greenhouses sheet thickness is crucial. The specified parameter directly determines such properties of the panels as the light transmission coefficient, the level of thermal conductivity and the ability to withstand mechanical loads. For the construction of greenhouses are usually used sheets with a thickness of 4 to 10 mm, the most suitable for the main parameters.

The thickness of the sheet is determined on the basis of the structural features of the frame; an increase in this parameter contributes to an increase in resistance to wind and snow loads. In some cases, different panels can be used on the same structure. For flat and arched roofs sheets of greater thickness are used, and vertical walls are made of thinner panels. The most optimal is the use of cellular polycarbonate with a thickness of 4 - 6 mm. At the same time it is necessary to make sure that the panel thickness declared by the manufacturer is actual. For this, the panel can be measured with a caliper. If the declared and actual thickness of the polycarbonate sheet do not match, the use of such material should be rejected.

Do not agree to buy polycarbonate with a thickness of 3.5 - 3.7 mm. At the same time, sellers can say that this material has a higher density, so it can be used instead of 4 mm thick sheets. But most likely it is poor quality polycarbonate, which has an extremely low life.

If polycarbonate bends easily from the impact of fingers and does not have a designation from which side the light-stabilizing layer is located, then you have cheap material that has a service life of no more than 2 years.

In the process of selecting cellular polycarbonate for the construction of the greenhouse, special attention should be paid to the following points:

  • Compliance with the thickness of the panel declared by the manufacturer and indicated in the documentation and on the packaging.
  • The presence of a protective film on both sides of the sheet, which protects them from premature wear.
  • Availability of accompanying documentation for the entire batch: certificates of conformity for products and passports.

Arched greenhouse

The arch greenhouse is a structure with a semicircular overlap. The spatial frame consists of arcs located at a certain distance from each other with transverse connecting elements. This type of greenhouses is most common among the population. The structure can be quite easily increased or reduced in length. This is done by adding or removing individual sections.

Arch greenhouse with lifting sides (butterfly greenhouse)

Such a structure has a rather modest size and is rather a greenhouse, its main convenience is the possibility of easy access to the garden and the organization of ventilation of the internal space, if necessary.

Greenhouse with drip arch

It consists of two curved surfaces the line of connection, which forms an acute-angled ridge. Such a device prevents the formation of snow cover on the slopes. An additional stiffener ultimately contributes to the strength of the structure.

Single or wall greenhouses

The simplest structure, which uses as a supporting structure the enclosing structures of residential or office buildings in the garden plots. During construction, a sufficiently large angle of the slope to the vertical is set, which prevents the formation of a stable snow cover on the surface. The building is located on the sunny side of the building to maximize the use of natural light.

Gable greenhouse

The duo-pitch classic greenhouse until the appearance of plastic polycarbonate was the only possible form. In appearance, it resembles an ordinary house with vertical walls and a flat roof. The simplicity of the design provides the possibility of its manufacture without the use of equipment for arching arcs for the arched frame. Such a design can be constructed from any materials, including wood.

When choosing the shape of the greenhouse, the owner is guided by several factors, primarily, its purpose and its own financial capabilities. For growing seedlings, a small wall structure or a greenhouse with lifting walls will be enough. Vegetable production will require solid arched or gable greenhouses with corresponding costs.

Sizes of the greenhouse and individual elements

When determining the size of the greenhouse, its purpose and planned production volumes are first of all accepted. Design work, even in the most simplified version, allows with sufficient accuracy to calculate the required amount of materials.

The general rules for performing this kind of event are as follows:

  • It is necessary to establish the length, width and height of this structure. This takes into account the area and configuration of the site and the convenience of working in the greenhouse.
  • Determined by the angle of the slope of the roof, providing spontaneous sliding of snow.
  • When determining the size of the doors should be borne in mind that the person in the course of the work will bring tools and agricultural equipment. In addition to the entrance in the wall provides folding transom for ventilation structures.
  • The frame device should be such that the joints between individual sheets of polycarbonate should fall on its elements. This approach can significantly enhance the design.

Fastening the structure to the foundation

The vast majority of greenhouses have a relatively light construction and significant windage, and can be flipped by the wind. Polycarbonate greenhouses must be carefully fixed to the base, which may be in the form of a strip foundation with a brick or stone base. The device of such a supporting structure requires significant investments and is used only for fairly large stationary greenhouses.

Fastening the supporting frame to the foundation is carried out through the use of embedded elements. Steel pipe constructions are usually welded to special metal parts embedded in the base. Galvanized profile frames are attached to the brickwork with dowel-nails or anchor bolts. The latter method of installation is more reliable.

The question of choosing a greenhouse from polycarbonate is reduced mainly to the determination of its size and shape based on its purpose and the capabilities of the owner. High-quality construction must be properly installed on the site, which will ensure its long-term operation.

The best greenhouse manufacturers - which company to choose

On the domestic market are many manufacturers of greenhouses. Most often, these are Russian companies that have considerable experience, and who know what the summer residents who live in our vast territory need.

Usually, finished greenhouses are manufactured in factories or made to order by companies engaged in the production of metal structures. The factories carry out a whole range of designs, offering the buyer a huge range of products.

The products of small firms, on the contrary, are not distinguished by a wide choice, limited to standard copies with minor differences in the configuration. Factory greenhouses can be purchased at specialized points of sale, without losing time in anticipation of the manufacture of products to order.

Here are some very popular companies:

This is not the entire list of sought-after manufacturers whose products are worthy of interest. To trust is up to you. For each region there are their own manufacturers, which can vary greatly among themselves.

Try to find and visit the official sites of such enterprises in order to learn more technical information, and not just advertising slogans. If you are already looking for a suitable model, then go to our ranking of the best greenhouses.

The principle of operation and the greenhouse

Теплица – это специальное сооружение, предназначенное для укрывания и защиты выращиваемой на ранних сроках рассады, например, перцев, томатов, капусты, огурцов, разных сортов зелени, цветов и прочего.

В последующем окрепшие ростки высаживают в открытый грунт. Система отопления и большие размеры дают возможность произвести весь процесс выращивания от посадки до сбора урожая.

Greenhouses consist of a frame and a covering material, which is usually polycarbonate, glass, polyethylene, etc. The heat generated from the pipes and the sun generated inside the structure heats the soil and the plants themselves.

The heated air is well kept by the walls and roof of the building. Usually, it is on the material of the walls that the success in capturing energy that goes to heat later.

Types of greenhouses

Arched greenhouses are an economical option. Due to the absence of sharp corners, such a construction would require significantly less covering material than, for example, a rectangular one.

There are hybrid versions of such buildings, they are dome-shaped. Precipitation in the form of snow does not linger on the roof, rolling down to the ground. Due to this, there is no pressure that can lead to the destruction of the greenhouse.

However, in regions with frequent and strong winds, arched forms should be avoided, as they are most often prone to breakdowns during strong gusts.

Advantages:

  • do not save snow
  • long service life
  • low cost

Disadvantages:

  • restrictions on the choice of coverage,
  • an insufficient maximum for some plants (up to two meters),
  • unstable to strong wind
  • difficult access to extreme beds.

Rectangular

Rectangular greenhouses are perhaps the most common. These are traditional buildings, usually having a gable roof. The areas for planting in such structures are larger than in arched models. True, covering material will also need more, and this will affect the final price.

Rectangular greenhouses provide excellent lighting even with a cloudy sky. Snow comes off easily due to the sharp corner of the slope.

Advantages:

  • attractive view
  • rapid precipitation
  • large area for landing,
  • convenience in operation.

Disadvantages:

  • complicated mount
  • relatively high price.

Polygonal

Polygonal greenhouses are rarely found on sites. Such a structure is expensive but effective. The set of faces (usually eight), located around the perimeter, the sun warms at any time of the day.

Most often wood or metal is used as a frame material, and glass serves as a covering material. These buildings look very beautiful and unusual, therefore they are able to transform any area.

Advantages:

  • original form,
  • warms up well due to the many faces
  • excellent transparency.

Disadvantages:

  • not easy to achieve a stable temperature
  • can accumulate snow on the roof,
  • high cost.

Walls

Wall greenhouses are called structures that are attached to the walls of houses, verandas or other buildings. Such structures have a shed roof. In shape, they can be both arched and rectangular.

This option of the greenhouse is the most economical, as there is a saving of building materials due to the presence of an already finished one wall. Experts recommend installing the structure on the south side.

It is also important to note that wall greenhouses need a smaller area, which means they are perfect for small areas.

Advantages:

  • saving land area
  • ease of use,
  • low cost

Disadvantages:

Frame material

One of the most accessible and popular materials. Its popularity is due to the low price and ease of processing. Despite the fact that the wooden frame is environmentally friendly, does not rust and has good thermal insulation qualities, it is considered imperfect. The main disadvantages include fragility, instability to moisture and fragility. When choosing this material, it is important to consider a moisture removal system to avoid rotting.

Among experts recognized as the most suitable material for greenhouses. PVC frame in Russia is used less often than others because of the high cost and complexity of processing. Plastic in greenhouses looks aesthetically pleasing, while it is durable, resistant to corrosion, rotting and various aggressive substances (acids, alkalis, fertilizers). It is lightweight and easy to install.

Similar frameworks gather from a profile or pipes. Profile is cheaper, but they are inferior in strength tube frames. In general, they are resistant to rust, light weight and ease of installation. Requires a minimum of care. Among the disadvantages are the low thermal insulation properties and relatively high cost.

In terms of price and quality, it is steel frameworks that benefit. Made of profile or pipes. They are durable, durable, withstand heavy loads, and all this at a fairly small price. There were no minuses here either: steel has poor thermal insulation and is also susceptible to corrosion. It is best to choose a galvanized, rather than a dyed material, since it will not need additional protection from rust for about ten years.

Covering material

In the past, it was glass that was one of the most sought-after materials for greenhouses. To date, many analogues have appeared, but they have not yet succeeded in completely removing the glass from the market. The material perfectly transmits light, has good thermal insulation, is resistant to temperature changes, durable and aesthetic. The main disadvantage is its fragility. It is important to choose a glass of at least 4 mm in thickness.

Cellular polycarbonate has the best value for money. Thanks to the air-filled honeycomb, the material becomes two hundred times stronger than glass, excellent light transmission is ensured, and the heat hardly reaches the outside. The low weight and ease of processing make polycarbonate even more attractive. For greenhouse walls, choose a thickness of at least 6 mm, and for a roof - 8 mm.

The cheapest and easiest to install material for greenhouses. It passes and gently diffuses the light, protects plants from light frosts (up to -30 ° C) and is suitable for structures of any shape. Polyethylene wears out quickly, especially in places of fasteners, so it will have to be changed often, about once every six months or a year. Experts advise to buy a reinforced or PVC film, because they are much stronger and can last several seasons in a row.

Size and equipment

The choice of size is a purely individual matter. General recommendations say that the width of the optimal design will be from 3 to 3.5 m, and the length - from 4 to 6 m. It is not recommended to buy longer greenhouses, since it will be much more difficult to care for the plants.

Consider also the packaging. The doors should be fairly wide, not less than 1 m, so that if necessary, you can freely transport the car. To have them best in both ends of the greenhouse.

The design should be equipped with at least several vents, for example, vents. If they are not, then the plants can burn. It would be nice to have on a covering material a specially applied protective layer that protects the seedlings from harmful radiation.

Which greenhouse to choose

1. Arched greenhouses are suitable for windless areas. Planted in them can be small in height culture.

2. Rectangular designs are good for growing tall plants.

3. Polygonal buildings differ in unusual appearance, therefore they will decorate any territory.

4. Wall greenhouses save site space, so they should be chosen for those who have a small land area.

5. The best option would be a frame made of aluminum or galvanized steel, the best not profile, and tubular.

6. Choose the best greenhouse made of polycarbonate.

7. Glass designs are not bad, but they are better to buy for places where there is no hail.

8. For buildings made of polyethylene should take a reinforced or PVC film.

How much is greenhouse

1. The cheapest are the models of arch forms, including the near-wall ones, the cost ranges from 5 to 15 thousand.

2. More costly rectangular greenhouses. The price for them is about 10-20 thousand rubles.

3. Polygonal buildings are the most expensive. Depending on the size and materials, they cost 15-40 thousand rubles.

4. Constructions in length up to 4 m cost from 10 thousand r, up to 6 m - from 15 thousand r, up to 8 m - from 20 thousand r.

5. Glass greenhouses have a price tag of about 10-30 thousand rubles.

6. Polycarbonate models will cost about 10-17 thousand rubles.

7. Greenhouses using polyethylene are in the area of ​​5-10 thousand rubles.

What is "happy" fake greenhouses?

Unfortunately, all kinds of yellow Chinese fakes are actively produced not only in the Celestial Empire. And in the domestic market there are a lot of underground models of well-known greenhouses. They cost a little cheaper than those sold by specialty stores, but they are significantly inferior in quality to the latter. As a result, in the World Wide Web every day there are new and new messages that another advertised greenhouse collapsed under the snow. The terrible photos are impressive, the owners of the crooked crumpled frame are genuinely sorry, but as soon as it comes to official complaints about the company, it turns out that the structure was purchased incomprehensibly from whom and there were no any protective license signs on it.

That is, outwardly the fake structure was very similar to its original, but it served only a year: the fasteners in the package were not fully delivered, the polycarbonate quickly cracked, the frame broke under the very first snow, corrosion spread through the metal parts ...

And in the end, 2-3 thousand rubles saved as a result, a new design is no longer to be bought, in fact, there is no one to file a claim: the selling company that manufactured the parts in a garage self-destructed after several months of work, and -or compensation or even to take the flexed frame for repair - after all, the greenhouse was not acquired from them, and it has no relevant documents, or they are fake ...

Official dealer or intermediaries?

Against the background of these messages of outraged and deceived buyers, grateful feedback from buyers of this brand stands out in bright contrast. And puzzled: “How broke? We are already in our seventh year, and she is not afraid of any snow. ” As proof, the owners of real greenhouses produced in the factory even show original photos, where 5-7 people simultaneously hang on a sturdy frame in the Mowgli pose. Because the whole thing is in the right choice, namely where and from whom it needs to be acquired. The ideal option in this regard is the company store or the website of the company itself, but working with intermediaries is to some extent a risk. And it is better to forget about little-known small firms and the elemental market forever. In any case, you should always carefully pay attention to the presence of the manufacturer's logo on the adhesive tape and on the protective layer of polycarbonate.

Frame "from the can"

The difference between the factory design and the difference made in the underground can be seen with the naked eye: the metal in such a frame is so thin that it bends easily and resembles the substance that makes up the can. But the metal frame of the greenhouse from the manufacturer where much more thoroughly, and it can not bend even a serious layer of snow, and he, as you know, can exert pressure even in several tons. This, of course, is not about economy options, of which there are quite a lot today. But they are just not intended for use in Siberian conditions, and those buyers who have decided to save by choosing a thinner profile should understand that they cannot do without a personalized upgrade and installation of supports.

After all, the arched design is always stronger than the gable, if it is, of course, made of the same materials. But the arch is expedient only with a sufficient thickness of its materials, because only then all the loads are maximally directed at compressing and evenly distributed throughout its entire supporting structure. Otherwise, the walls of the building work for a fracture, which often happens in fake fragile frames.

Chinese polycarbonate

In ornamental designs, not only is the thickness of the pipe reduced, but the polycarbonate itself can be of disgusting quality. So, it is not uncommon today that a Chinese coating, which is not intended for external structures at all, turns out to be on the purchased greenhouses. In this case, it is better to immediately replace it with an Israeli with its ultraviolet layer, which is still considered the best. Check the quality of the material is easy enough - you need to try to push it with a man's hand. If at the same time the stiffeners are not deformed, it means that the coating will serve faithfully for more than one year.

Economy design

Sometimes, also, the basic model is given its more economical version, intended either for the southern regions that are calmer in terms of the winds, or at the disposal of summer residents who like to improve everything with their own hands. For example, it often happens when allegedly “dacha-2DUM” is sold, but in fact it turns out that it is “Dachnaya-2DUM-economy”. And the differences between them are quite significant: in the “economy” the step between the arcs is a whole meter, and there are, of course, no amplifiers for them in the package bundle. In addition, such options "economy" always require the mandatory dismantling of polycarbonate for the winter, and this is even stated in their instructions. That is why their real price is much lower than the base model. And it is very easy to recognize the substitution: just ask to extract instructions from the bundled equipment and see all the points well in it.

That is why the ideal way to get a good quality greenhouse is to contact directly the company that represents the manufacturer, and not the intermediary. Moreover, the manufacturer known and trusted. And, of course, it is all the same to pay close attention to the presence of all logos, important points in the instructions and all fasteners in the configuration. That's when for the most spectacular construction on the site you can not worry, collecting every year the best harvest!

How to choose the right greenhouse polycarbonate?

All greenhouses offered for sale are frame and cover. Let's talk more about each so that you can decide for yourself which polycarbonate greenhouse is the best, as well as how to strengthen the frame of the country greenhouse.
This will help you video located below.

In greenhouses installed in gardens and cottages, the frameworks can be:

  • Plastic,
  • Wood,
  • Metal,
  • Aluminum.

Each of the frames has its advantages and disadvantages.

Probably the most inexpensive greenhouse frames. Besides, they do not rot, are not subject to corrosion, and do not need additional treatment. These are the parameters that can be attributed to the pluses of this framework.

Speaking about how to choose a greenhouse from cellular polycarbonate, we note the disadvantages.

Pretty complicated installation. Because of the continuous greenhouse production system, the inconsistencies of components are quite frequent. Light snow load. Whereas in Moscow the average snow cover load is about 140-160 kg per square meter. Even the optional racks may not help.

And the main disadvantage of such frames is lightness. Requires a good attachment to the ground or foundation.

It warms up well during the day, at night, when it cools, it gives off heat, maintaining the temperature. Ease of fastening facing material. Probably it the only advantages of making a wood frame.

Let's say about the shortcomings.

It takes a lot of time to install the frame, desirable treatment with linseed oil or varnish in order to slow down rotting due to high humidity, it is necessary to treat the instilled part of the racks with tar or, if possible, sheathe them with roofing paper, to slow down rotting.

Can say the best option.

  • Aluminum is not subject to corrosion,
  • Resistant to moisture
  • Relatively easy if you need to transfer to another place.

If it were not for several reasons to consider the use of this option.

  • Fast heat emission at night, and as a result creation of cool zones around the pipes.
  • Pretty big price,
  • The inability to leave the country due to the theft of non-ferrous metals.

Metal frameworks of greenhouses are made from different types of profile, V, M and P - shaped. V and M-shaped, according to numerous reviews, is recommended only in places with little snow cover in the winter period. P - shaped is much more powerful. But he can not withstand the load of snow more than 110-120 kg per square meter.

The best option for the conditions of the Urals and Siberia is solid arches from a square tube of not less than 25 × 25 mm, with a wall thickness of at least 1.5, preferably 1.8 mm.

Attention should be paid to whether staining is required to protect against excessive moisture inside the building. Worth abandon this option in favor of galvanized arches. Otherwise, after two, three years you will have to remove the polycarbonate panels for a careful repainting of the arches of your greenhouse.

Do not fall for the assurances of the sellers that their greenhouse is “of excellent quality and inexpensive.” Where there is "free cheese", I think it is not necessary to remind. Polycarbonate greenhouses: how to choose the best is the whole art!

Outer cover

Good coverage when building greenhouses with steep roof slopes. К недостаткам можно отнести малую снеговую нагрузку, а также необходимость мощного фундамента, иначе строение поведет и стекла растрескаются.

Этот вариант покрытия больше подойдет для зимней теплицы при условии использования однокамерного стеклопакета.

Относительно неплохой вариант, особенно если пленка специальная с высокой способностью пропускать ультрафиолетовое излучение. More advantages can be attributed ease of installation and delivery.

The main disadvantages are the fragility and the need to clean the film for the winter period.

Polycarbonate

Ideal for coverage. Polycarbonate is able to take the desired shape and withstand a considerable load, subject to certain rules for the selection and care of the greenhouse.

If you are going to grow a large range of plants, then the best option is to buy a transparent polycarbonate. But what polycarbonate is used for greenhouses?

Pay attention to the thickness of the sheet. If less than 4 millimeters, then you should not purchase. Although it is possible, provided the coating of the frame with two layers of polycarbonate.

Pretty good performance for sheets with a thickness of 6 millimeters, which have an additional inner layer, which will not allow condensate to accumulate inside the greenhouse made of polycarbonate. The best specialists in the opinion and in terms of repairing their own hands are polycarbonate greenhouses.
pay attention to the presence of a coating that protects the polycarbonate from damage under the influence of UV radiation. And also do not forget about the foundation for a greenhouse made of polycarbonate.

The layer that protects against ultraviolet radiation during installation should be facing up. Laying on the contrary will lead to a reduction in the service life of polycarbonate instead of the declared 10 (actually about 15) to 3, maximum 4 years.

Also not suitable for use sheets labeled "for use indoors." They do not have protection from exposure to the sun. To protect the most commonly used method of coating varnish.

You should not buy sheets of polycarbonate, which is marked "Economy". This is an indication of the presence of a recycled polymer, which reduces the strength of polycarbonate sheets.

Correctly choose a greenhouse from polycarbonate will help you the video below.

So, you have decided from what will be the arches of the greenhouse frame, and also decided on the thickness of the polycarbonate plates on the floor. Consider purchasing specialized hardware. This includes items holding the polycarbonate securely in place, excluding polymer breaks and water entering through them.

With repeated exposure to moisture and sun, the adhesive tape will come off, and microorganisms will fall into the open channel. As a result, light transmission will decrease, and also your greenhouse will shine with a "green, marsh" color. Processing is carried out by a vapor permeable sealing tape.

Internal equipment

If there is no opportunity to live in the summer cottage or often come to maintain the microclimate in the greenhouse and watering, then think about the automatic watering system. More often hose routing requiredraised above the level of the greenhouse storage tank and watering time sensor.

If there are air vents, install an automatic ventilation system, it will provide the necessary temperature throughout the day.

The virtues of good polycarbonate greenhouses

  • Damage resistance, compared to glass and film greenhouses,
  • Polycarbonate, thanks to plasticity can provide any form of greenhouse,
  • Maximum light transmission to plants,
  • Long service life in comparison with greenhouses from other materials.

disadvantages

Perhaps the most significant of all the identified deficiencies is its high price, when compared with greenhouse prices from other materials.
