Polycarbonate greenhouses have gained their popularity due to their practicality and low cost. They are easy to transport, quickly assembled and perform their function for a long time. It becomes more and more difficult to meet glass or film counterparts every year.
Despite all its advantages, polycarbonate greenhouses have one serious drawback. In winter, structures are often deformed under the pressure of the snow. Repairs are not cheap. Broken sheets and bent frame elements must be completely replaced. The cost with delivery is such that sometimes it is more profitable to buy a new greenhouse.
To avoid serious damage, the greenhouse must be prepared for the coming winter. How to do it? Let's figure it out.
Some growers leave their greenhouse doors open to allow snow to enter. Land saturated with melt water is considered more fertile and of better quality. Such actions reduce the strength of the structure, as a result of which the frame can lead. You even need to close the vents for ventilation. In a snowy winter, the integrity of the structure will help to avoid significant deformations.
In greenhouses of the middle price segment, the distance between the support arcs is often more than 1 meter. This can significantly reduce the cost at the expense of the strength of the frame. In this case, additional supports can be installed. They are made from thick boards or small-diameter bars. You can strengthen both metal arcs and the polycarbonate sheets themselves.
During the autumn cleaning of the site, barrels, benches, poles, ladders and other items of summer cottage life are often placed against the walls of the greenhouse. All of them prevent snow from melting from the roof, as a result of which it accumulates in large quantities. To prevent this from happening, the area next to the greenhouse must be left free.
If the greenhouse is located near trees and tall shrubs, fallen leaves and small twigs should be removed from the roof. Such debris forms an ice crust that prevents snow from melting. As a result, the heavy cap bends the structure and breaks the polycarbonate.
These simple rules will help to avoid damage to the greenhouse, even during heavy snowfalls.
