Prefabricated house first choice!

line

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.
