Double-layer inflatable film greenhouse has good insulation

2024-12-16

The double-layer inflatable film greenhouse uses transparent plastic film as the covering material, which is relatively low in cost. It is also beautiful and practical. It is popular in the production of facility agriculture and is widely used in various vegetables, fruits, flowers, seedlings, planting production, special breeding, etc., with obvious advantages.

The film covering the multi-span plastic film greenhouse generally uses a single-layer film. In the northern region of my country, in order to further improve the performance of the multi-span film greenhouse, some will use a double-layer film structure. The double-layer inflatable film technology is a double-layer film application with excellent performance.

The multi-span plastic film greenhouse can increase various greenhouse supporting systems such as internal and external shading, heat preservation, ventilation and cooling.

The double-layer inflatable film technology of the multi-span plastic film greenhouse is a new technology to enhance the thermal insulation performance of greenhouse plastic film. The double-layer inflation technology is to fix the four sides of the plastic film, inflate the membrane with an air pump, and then fix the inner film on the greenhouse frame. The outer film is supported by air pressure. It is a structural form of combined insulation of double-layer film and air interlayer. Experiments have shown that compared with single-layer plastic film greenhouses, double-layer inflatable greenhouses can save 30%-40% of their energy.

Double-layer inflatable film can not only be used directly as a protective lighting material for plastic film greenhouses, but can also be covered on multi-span glass greenhouses or other hard material multi-span greenhouses. For example, covering it on the roof and wall can improve the thermal insulation performance of the entire greenhouse. Experiments have shown that the thermal insulation performance of a single-layer glass multi-span greenhouse covered with a double-layer inflatable film is nearly 55% higher than that of a single-layer glass multi-span greenhouse.

The double-layer inflatable film technology used in multi-span plastic film greenhouses is simple, cheap, and has good thermal insulation performance. It has good adaptability and excellent performance in greenhouses in northern regions.
