In a good greenhouse, it also requires careful daily maintenance. It takes longer to use it. The covering material of the multi-span greenhouse is generally sunny board or glass, and the thermal insulation performance is also very good, but the interior of the multi-span greenhouse is also equipped with heat preservation measures, which is called internal heat preservation in the industry, which is a very thin waterproof quilt. It is different from the heavy quilt in the solar greenhouse. The multi-span greenhouse thermal insulation is installed at the top and around the indoor, and the multi-span greenhouse adopts the form of internal thermal insulation. The configuration of the multi-span greenhouse belongs to the greenhouse industry, and both external sunshade and internal thermal insulation are configured. Places like the northeast have to be equipped with internal thermal insulation. But it is not called thermal insulation, the thermal insulation of the traditional solar greenhouse is covered outside the greenhouse, but the thermal insulation of our multi-span greenhouse is inside the multi-span greenhouse, and the general installation location is at the top.
In addition to hygiene and epidemic protection, sunscreen is also very important. Sunscreen and physical protection (hat, sunscreen, sunshade) can be used together. Finally, I wish you all a pleasant picnic experience ~
