When it comes to heating in winter, we must first discuss the insulation of the greenhouse. The insulation effect of the greenhouse is poor, and the heating cost is high. Therefore, a greenhouse with poor airtightness must have poor thermal insulation. Due to the large temperature difference between the north and the south of our country, the traditional requirements for greenhouse construction are also different.

Both the south and the north must consider the airtightness of the greenhouse when designing and building the greenhouse, so as to ensure the reduction of heating costs and improve the quality of flowers.
There are several ways to improve the airtightness of the greenhouse: In the design and construction of single-arch sheds, energy-saving solar greenhouses, and multi-span membrane greenhouses, attention should be paid to adding insulation films to both ends of the insect-proof nets, and burying the skirt films in the soil, In order to achieve the function of heat preservation and energy saving.
For multi-span film greenhouses, a 30-50cm brick wall should be built around it, which can play a good role in heat preservation. In addition, the ends and sides of the multi-span film greenhouse should be firmly fixed and tightly sealed to prevent air intake.
If it is a multi-span glass greenhouse and a multi-span PC solar panel greenhouse, on the one hand, a brick wall of 50 to 100 cm should be built around it; It must be sealed with glue.
