Many residents of country cottages prefer to take part of their land to be under a garden or a garden. To improve the efficiency of cultivation of cultivated plants in the yard greenhouses are equipped. In recent years, polycarbonate greenhouses are increasingly being constructed. They hold the desired temperature and humidity well, are quickly erected, and, which is important for private households, look very aesthetically pleasing.

Polycarbonate greenhouse in the area

What is polycarbonate

There are two types of polycarbonate - cellular and monolithic. For roofing work, as well as for the construction of auxiliary buildings on the site, including gazebos and greenhouses, the cellular version is used predominantly. It is a transparent, flexible sheet material consisting of three layers:

  • Top layer . It is a polycarbonate sheet, which is covered on top with a protective film that does not allow the sun's rays to destroy the material.

  • The middle layer is a cellular layer. Hollow cells with polycarbonate walls give the material high thermal insulation characteristics, and also make it lightweight. The walls of the cells at the same time act as a kind of stiffening ribs, so that the material has a rather high strength.

  • The bottom layer is another solid sheet of polycarbonate, but without a protective coating.

Advantages of polycarbonate greenhouses

Not yet For a long time for the construction of greenhouses used only glass and polyethylene. In the first case, heavy and fragile structures were obtained, which are also quite difficult to install. And the use of plastic film did not usually justify itself, since this material wears out quickly, and it also collects dirt and dust on itself. Therefore, when it became possible to make greenhouses from practical and convenient polycarbonate, many homeowners enjoyed this opportunity with pleasure.

The advantages of greenhouses from the new improved material are:

  • strength , allowing the structure to withstand the weight of a sufficiently thick layer of snow;

  • good transparency , because all layers of the material are completely transparent and nothing prevents the sun's rays from penetrating inside;

  • low thermal conductivity , thanks to which the plants in the greenhouse are protected from cold and sudden changes in temperature;

  • durability , allowing to use the structure for at least 5 years without restoring and not repairing ontiruya it;

  • low weight , allowing you to use not such expensive materials for the frame and foundation as in the case of glass greenhouses.

Which polycarbonate to choose

The main characteristics for the greenhouse are good light transmission, reliable heat retention and strength. To obtain a design with optimal performance, use polycarbonate sheets with a thickness of 4 to 10 mm.

The thinner the material, the more expensive and heavier it is. Some bona fide manufacturers use polycarbonate of different thickness in the creation of a single design. Thus, the elements of the arched form are subjected to more severe loads during strong winds and precipitation, so they are made of thicker material. Straight and side walls can be constructed from thinner polycarbonate.

Polycarbonate sheets are available in standard widths - 210 cm. Sheets can be 6 or 12 meters long. These parameters are taken into account when drawing up the drawing of the future greenhouse.

It should be noted that the quality of the finished greenhouse directly depends on the characteristics of the polycarbonate. At the same time on the market today there are a large number of fake material that does not have the stated properties. This means that you should only buy ready-made plaster or material from reliable suppliers who have extensive experience and an impeccable reputation.


In order for the construction to last as long as possible, you need to choose the right material for the frame that will hold the walls of the greenhouse. The most economical option - a frame made of wood. If the wood before installation is treated with a special protective antiseptic, its service life will be at least 10 years.

More reliable, but more expensive will be a frame made of a metal profile. This is the option used by manufacturers. The metal frame will last longer than wooden, and in assembly it is much more convenient.

It is advisable to install a greenhouse on the foundation, despite the fact that its weight will not exceed 200 kg and the risk of subsidence on the ground under its own weight is minimal. The fact is that, firstly, in winter, sediments deposited on the greenhouse walls will significantly increase its weight. In addition, if it stands without a foundation, then cold air from outside can penetrate through the gap between the ground and walls. There are cases when during the summer at night the air temperature dropped below zero. In the greenhouse, standing on the "bare" soil for an ode on such a night can kill all the plants.

Another reason to make an uncomplicated foundation is that it will provide good protection against the penetration of weeds and harmful insects. And for high-quality fixing of the frame it is also needed.

Foundation for greenhouse from polycarbonate

There are various options for arranging the foundation for a greenhouse.

  • Wooden . The cheapest type of foundation, which is constructed from a timber and, if necessary, can be moved to another place.

  • Block . It is equipped with the use of concrete blocks. Suitable curb blocks used \ y. This option is ideal for areas with high humidity.

  • Brick . It is necessary when it is planned to grow plants in spring and autumn.

  • On the supporting posts . The simplest type of base, suitable for small summer greenhouses.

The optimal width and length of the greenhouse

By size greenhouse must comply with the area of ​​the site and its purpose. It should be borne in mind that it should not be covered by the shadow of other objects, and next to it you need to leave space under the open beds. Experienced gardeners recommend the following sizes of greenhouses:

  • wall height - from 160 cm;

  • width - from 235 cm;

  • length - from 6 meters (according to the length of the polycarbonate sheet).

It should be taken into account that with a wall height of 160 cm, the ridge will be much higher. The minimum width is calculated on two beds and the passage between them. If you have the desire and ability to have a greenhouse with several beds you can make it wider. So, each additional bed will take another 1 meter + 35 cm per pass.

The length of the greenhouse may be quite large, but it is advisable to plan it a multiple of 6 meters - along the length of the sheet of material. The best option is the construction of an elongated shape into two beds with a passage. The more plants are planned to grow, the longer should be the greenhouse and the beds in it. However, if it is impossible to allocate a long elongated part of the yard for the construction, it is possible to build a square or even a round greenhouse.

Greenhouse shape

Polycarbonate greenhouses are manufactured in several standard configurations. They are odnoskatnymi, gable, arched and drop-shaped.


A structure with a shed roof can be either standing or attached to the wall. Wall option is ideal for small areas. The advantages of such a greenhouse are:

  • good heat resistivity;

  • economical consumption of materials;

  • easy installation.

There are some obvious disadvantages:

  • the wall of the house does not allow the greenhouse to fully warm up;

  • the structure may suffer from snow or ice falling from the roof of the house.

A construction resembling a classic house. Suitable in cases where you need to build a greenhouse made of polycarbonate, whose dimensions are larger than average. It has the following advantages:

  • maximum usable area;

  • allows you to grow tall plants;

  • good light permeability;

  • simplicity in arrangement of the ventilation system.


  • increased material consumption, which affects the final cost of the structure;

  • is necessary make sure that at the junction of the slopes and walls remained sealed.

The most practical form. It does not have a joint between the walls and the roofing part, and at the same time the arched configuration contributes to the rapid and effective removal of precipitation.


  • The arched structure can be of any size, since it is easy to assemble the framework for any dimensions you like;

  • high wind resistance;

  • mobility - it can be easily removed and installed elsewhere;

  • low material consumption.

Of the disadvantages:

  • is not suitable for growing high crops;

  • it is difficult to arrange ventilation.

Drop-shaped greenhouses have the most aesthetic design. Combine the characteristics of the arched and gable design.


  • increased durability;

  • precipitation is well discharged from the surface of the structure;

  • high light transmission.


  • assembly complexity;

  • high cost.

There are more original forms of such structures. For example, you can build a mini-greenhouse with an opening top in the form of a breadbasket or a round domed greenhouse. The choice depends on what requirements are imposed on the structure. The most practical options are the gable and arched shape.
