PIR Sandwich Roofing Panel is a high-quality choice for building roofing.Its thermal conductivity is only 0.018-0.025W/(m · K), heat insulation is extremely strong, can greatly reduce indoor and outdoor heat exchange, reduce energy consumption.It is light but compressive, can reduce the building load, but also can withstand the impact of wind and rain. The closed cell structure makes it waterproof and reduces leakage.And anti-aging, corrosion resistance, long service life, low maintenance cost. High degree of prefabrication, convenient construction and installation, can shorten the construction period.
