Greenhouse characteristics:
The greenhouse is a kind of more economical and practical, because the top covered film is much cheaper than PC board, and the façade PC board or glass are sturdy and durable, very popular among individuals. This type of greenhouse is generally divided into two categories: double arch double film greenhouse and single arch double-layer inflated film greenhouse.
1. Double arch double film greenhouse
The opening window system of the double arch double film greenhouse generally adopts roller film window, both sides of the outside film can be rolled to a 1-1.5m long ventilation window on the top, inside film can be rolled to the top, ventilated effect is very good. this type of greenhouse is surrounded by hollow sunshine board or hollow glass, and the top is covered by double plactic film, the heat insulation performance is better than single-layer film greenhouse in winter.
2. Single arch double-layer inflated film greenhouse
Single arch double-layer inflated film greenhouse has two layer films on the top, the two layers films are fixed by slot and rings, Electric pneumatic mechanism will be set among the two layer films, window system generally adopts the motor gear rack outside to open the window. This structure is compact, and can realize automatic control, also cost cheaper.
