Industrial greenhouses made of polycarbonate: pros and cons
Summer residents and farmers have been using greenhouses for growing early seedlings: seedling flowers, tomatoes, cabbage, cucumbers, growing potted plants and what not.
Garden greenhouses are covered with various materials, from glass to plastic. However, at the moment, most land owners mainly choose polycarbonate greenhouses or DobroTA film greenhouses. They are united by fast assembly and protection of seedlings from external factors, but at the same time there is a huge difference between the two popular materials.
- good thermal insulation abilities;
- simple processing with cutting tools;
- easily takes the desirable shape.
- exposed to thermal expansion;
- hygroscopicity (absorbs water vapor from the air), therefore, in combination with - dust, dirt streaks form on the surface and the transparency of the plastic decreases;
- exposed to UV rays (turns yellow over time);
- requires periodic replacement, because subjects to structural changes;
- insufficient protection against mechanical damage;
- high cost of material.
- minimal time of consumption for the construction of a greenhouse;
- if damaged, you can easily repair the greenhouse;
- due to chemical additives it retains heat better and is not affected by UV radiation;
- good resistance to wind loads and frost (easily withstands temperatures down to -80 ° C);
- retains elasticity even at subzero temperatures;
- maximum passage of sunlight;
- efficiency in terms of price.
- lends itself to mechanical stress from the outside.
