Since as much as 60% of the heat is lost from the front roof, a novel internal insulation was proposed to improve the thermal insulation capacity of the unheated CSG. The traditional single-layer front roof was transformed into comprehensive external and internal thermal insulation to reduce nighttime heat dissipation.
Therefore, it is necessary to reexamine the single-layer front roof insulation of the traditional unheated greenhouse, and search for an energy-saving design scheme for cleaner production. Some researchers have tried to use double-layer front roof insulation to reduce the heat loss in the greenhouse.
