rigid polyurethane has moisture and water resistance. The rigid polyurethane has a closed cell ratio of more than 90%, and is a hydrophobic material. It does not increase the thermal conductivity due to moisture absorption, and the wall does not seep.
polyurethane material porosity structure is stable, basically closed-cell structure, not only excellent thermal insulation performance, but also anti-freeze-thaw, sound absorption. The average life of the rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. It can be destroyed under normal conditions of use during the life of the structure, dry, wet or galvanic corrosion, and due to external factors such as insects, fungi or algae growth or damage caused by rodents.
