Polyethylene film hothouses need to be replaced annually. Those who use this variant cover, know exactly how troublesome to clean up greenhouses with the onset of the season. A perfect solution to this problem becomes covering greenhouses cellular polycarbonate. However, it is important to avoid mistakes when installing the polycarbonate sheets to the frame structure.
Why is better to choose a greenhouse polycarbonate
Commonly considered two types of greenhouses - metal and wood. However, their shape is unimportant for the polycarbonate coatings, since even on curved frames sheets lie perfectly adapting to curves.
Durability polycarbonate sheets is significantly higher than that of glass, a comparison with a polyethylene film and does illogical. Preservation of functional qualities of polycarbonate is provided with a special protective coating that protects the material from ultraviolet radiation. Polycarbonate sheets can be 10 years to 15 with full strength and transparency.
How to cover the greenhouse
Difficulties in covering greenhouses polycarbonate https://poly-max.com/katalog/polikarbonat/ there should not be, if you remember some rules.
A few basic rules covering greenhouses polycarbonate:
- The cavities inside the polycarbonate sheet at temperatures drop, condensation and moisture accumulates. That is why only the sheets should be placed vertically, since in this way the condensate will flow down easily from the cavities.
- The recommended thickness for greenhouse polycarbonate - 4 millimeter. This thickness is sufficient for producing high quality greenhouse. The fact that the thicker sheets are more expensive, and the service life is practically the same for all variants. The focus should be given to selecting the polycarbonate sheet density (it should not be less than 0.5 kg / m2) and thickness of the protective layer from Ultraviolet (it should not be less than 30 microns).
- Undoubtedly, it is important to understand that you get a quality product. The buyer can always ask the seller a certificate of quality, which confirms that the polycarbonate produced at the factory in accordance with the stated specifications. Conscientious manufacturer provides the above mentioned certificates with each consignment.
- It is important during installation time, pay attention to the size of the holes that are made to secure the sheets. They should be more self-tapping screws 2-2.5 millimeters. This is basically because polycarbonate expands or contracts with temperature changes. It is also important not to press in the panel with screws, as this damages the polycarbonate. In order to reliably block mounting holes and eliminate damage to polycarbonate, special thermowashers used.
- Polycarbonate sheets are bonded with special profiles. It can be as aluminum parts, and polycarbonate. As a rule, use the connecting and end profile. The use of end profiles is especially important to cell is not clogged with dirt and insects. In the absence of protection, greenhouse, with high probability, lose transparency and good appearance.
Carrying out these simple rules, you can create a robust design.. And if you stick to the proper care of a greenhouse, for example, make a backup ridge greenhouses in the winter, wash only special means or clean water, the polycarbonate will last a long time and maintain its quality during the entire period operation.
