Prefabricated house first choice!
Prefabricated house, also called industrialized house, is a residential building which is assembled
partly or completely in the factory and then transported to the construction site. The use of polyurethane
pouring system in prefabricated wall panels can realize automatic production. The formation of
dense polyurethane insulation layer in between the precast wall panels can closely bonded with
cement base. Polyurethane is an excellent thermal insulation material, it reduces wall
thickness, improves energy & land saving, as well as material saving.

TECHNOLOGY
ADVANTAGE
Polyurethane insulation material has excellent thermal insulation performance, and can meet different flame retardant grade requirements through formula adjustment. Its continuous dense insulation layer is especially suitable for roof insulation and waterproof integrated application, roof spraying and wall insulation.
PROCESS
Mainly for the spray, pouring and discontinuous production of block foam
TECHNOLOGY
Mature technology, customized according to customer requirements
