Probably first of all the owners of summer cottages are planning to install a greenhouse. Experienced gardeners, despite the long-term cultivation of vegetables in the open field, also come to the need to build a protected shelter. Here with what covering, what form and the size it is necessary to know.
After all industry offers a wide range of diverse greenhouses and encloses polycarbonate greenhouse assembly instructions. How to choose a suitable greenhouse, given the large variation in prices, forms and coatings. To do this, you need to know the advantages and disadvantages of the greenhouses on sale.
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.

Frame
In greenhouses installed in gardens and cottages, the frameworks can be:
- Plastic;
- Wooden;
- Metal;
- Aluminum.
Each of the frames has its advantages and disadvantages.
Plastic
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.
Tree
It warms up well during the day, at night, when it cools, it gives off heat, maintaining 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.
Aluminum
Can say the best option.
- Aluminum does not corrode;
- 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
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
Glass
Good coverage when building greenhouses with steep roof slopes. The disadvantages include a small snow load, as well as the need for a strong foundation, otherwise the building will lead and the glass will crack.
This variant of the coating is more suitable for a winter greenhouse, provided the use of a single-chamber glass unit.
Film
A relatively good option, especially if the film is special with a high ability to transmit ultraviolet radiation. 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 assortment 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.
Fittings
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
- Resistance to damage, in comparison with the glass and film greenhouse;
- Polycarbonate, due 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.
Invite a specialist. Having established the greenhouse, you can start long-term operation, providing yourself and family with the grown fruits.
Now you know which greenhouses are good, and which ones are not polycarbonate. If you are interested in how to build a greenhouse of wood under polycarbonate yourself, follow the link.
