Adopt the new generation PU PIR Pentane-blown B1 foam as the rigid  core material, Wiskind produces the PIR PUR PU Polyurethane Insulated Wall Sandwich Panels(COLORGEM®) which boasts excellent heat insulation and fireproof  performances. Ultra-high temperature stability and fire rating, zero Freon emissions,  energy saving and eco-friendly, thus able to be widely used in industrial  building and cold storage projects.

Cold storage doors refer to doors that are installed in cold storage equipment, freezer warehouses and other refrigerated environmental equipment to keep heat and seal.The cold room doors adopt high-strength aluminum alloy profile door frame, which has high strength, no deformation, beautiful appearance and durability; the door leaf is surrounded by 2.0mm stainless steel edging and seamless welding, which is strong and durable, without deformation, and has a reasonable structure.

Polyurethane cold storage sandwich panels are moisture-proof and waterproof. It is a hydrophobic material in essence, which eliminates the phenomenon that the thermal conductivity is affected by heat absorption and the occurrence of water seepage on the wall; it has strong thermal insulation performance, extremely low thermal conductivity, excellent processing performance, and is still all thermal insulation materials at present. The one with the lowest thermal conductivity among them not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption performance. So it is very suitable for greenhouse to use.
