Therefore, good thermal insulation performance is the primary requirement for the thermal insulation quilt. Secondly, the greenhouse insulation is required to be rolled up after sunrise and put down before sunset, so the corresponding insulation system is also a kind of movable rolling system, so the insulation material is required to be flexible. Third, after the installation of the solar greenhouse insulation, it will always work in the outdoor conditions. Therefore, it is required to be able to prevent wind, water and aging to adapt to the daily wind, rain, snow, hail and other natural climate conditions.
