The difference between single-layer film multi-span greenhouses and double-layer film multi-span greenhouses

1. Single-layer film multi-span greenhouse

Single-layer film multi-span greenhouses are covered with a single-layer film around and on top of the greenhouse frame. It is a greenhouse type that has just been introduced and promoted in my country, and it is also a greenhouse type that is currently used more in coastal areas. This type of greenhouse has good light transmittance, good ventilation, and good economic returns. It is more suitable for crop planting, seedlings, etc. However, this type of simple film greenhouse has poor thermal insulation performance in North China. Even if heating equipment is installed in winter, it consumes too much energy. In North China, it is generally used as an autumn and spring greenhouse. At the same time, this type of greenhouse can be equipped with intelligent equipment such as electric vents, fan wet curtain forced cooling system, etc.

2. Introduction to double-layer film greenhouse

Double-layer film greenhouses are used in North China to better solve the problem of heat preservation in winter. A layer of film is installed inside and around the greenhouse in an effective way. The greenhouse with double-layer film in this type of greenhouse is generally covered with a double-layer film on the outside and a single-layer film on the inside. After installing the double-layer film, the light transmittance effect is reduced, so it is generally used as potted flowers, seedlings, etc.

Of course, there are also some used for picking gardens. It is also a good choice to replace certain holes with glass to cover them for better appearance.
