Polyurethane thermal insulation spraying, also known as cold storage spraying. Cold storage spraying is a spraying technology. Polyurethane rigid foam body closed cell rate ≥95%, water absorption rate ≤1%, energy saving and heat insulation effect is good, polyurethane rigid foam is a high-density closed cell foam compound, thermal conductivity ≤0.022W/ MK, energy saving effect is good. Polyurethane rigid foam is directly sprayed on the roof layer, which is a reaction to the pressure of the material and directly foamed into the mixture by spray gun.

Features:The construction is simple and rapid, simplify the overall construction process of the roof mechanized construction, less construction personnel, reduce safety risks, a set of imported equipment in good conditions can be completed every day 800-1000 square meters of construction, than the conventional waterproof insulation material construction time saving 80%.

Old roof maintenance and reconstruction, when the old base did not take off, drum, can not eradicate the old base, directly in the old base spraying construction to reduce the intensity and difficulty of the project, save the project cost and construction time, fluorine free foaming, green pollution-free advanced fluorine free foaming technology, in line with the requirements of environmental protection.
