PU wall sandwich panels are generally used for building exterior walls and have good heat preservation, heat insulation and sound insulation properties. The PU structure is adopted in the middle of the upper and lower steel plates to make the sandwich panel have high strength, high rigidity, strong resistance to deformation, clean and sanitary, convenient installation, short construction period, and beautiful appearance. It is a new type of environmentally friendly building material.

The PU sandwich panel is a closed-cell structure with stable structure. It not only has good insulation properties, but also has good sound absorption properties. Under normal use and maintenance conditions, the average life span of rigid polyurethane insulation structures can reach more than 30 years. It is widely used in the wall, logistics storage and roof enclosed systems of integrated houses.
