It is formed by tens of thousands of sealed bubbles, allowing only a trace amount of air to enter, blocking sound and temperature penetration, with good effect, sound insulation B, and thermal insulation R value. It is light in weight, one inch thick, and weighs only .3 pounds per square meter, which is equivalent to the weight of concrete. This reduces construction costs. High load-bearing capacity, one inch thick, can withstand pounds of pressure per square meter. Waterproof, its water absorption rate is extremely low, and it has a completely waterproof effect after special surface treatment on both sides. It has good fire resistance. According to the results of American experiments, the hard insulation board neither spontaneously ignites nor supports combustion. It is flexible to use. Due to the continuous production line and computer control, the length of the sandwich panel can be determined according to the design requirements and transportation and installation conditions. Different sandwich panel thicknesses can be selected for different roof loads and purlin distances. Main application areas: thermal insulation/refrigeration/dry cargo compartments, large-span structural roofs, walls, thermal insulation (or fireproof) factories, purification factories, high-end and high-end modular houses, cold storage, container houses, etc. The product has beautiful appearance, bright color and strong load-bearing, thermal insulation, fireproof and waterproof properties. Customers are welcome to call us for negotiation!
