The invention discloses a multifunctional
greenhouse insulation device, comprising a first heat-reflecting layer, a first
insulation layer, a tensile layer, a second
insulation layer and a second heat-reflecting layer; the first
insulation layer, the tensile layer, the second insulation layer and the second heat-reflecting layer are disposed in succession below the first heat-reflecting layer, and the adjacent
layers are connected by bonding; the first insulation layer, the tensile layer and the second insulation layer are combined in a stair form; the multifunctional
greenhouse insulation device with the heat-reflecting
layers made with PET aluminized film has good heat reflecting effect, can reflect heat dissipated out in a heat
radiation manner from the inside of a
greenhouse, back into the greenhouse, can reduce dissipating speed of the heat in the greenhouse and has good waterproof, anti-
ultraviolet and insulating properties; cross-linked
polyethylene foam material for the insulation
layers of the multifunctional greenhouse insulation device is closed-
cell foam material, heat conduction coefficient is low, and good waterproof and
moisture-proof functions are imparted.
