Fireproof soundproof door uses high-temperature resistant calcium silicate core material (fireproof)
The fireproof soundproof door uses high-temperature resistant calcium silicate core material, which is a type of inorganic board with very stable physical and chemical properties. It has excellent characteristics such as high heat resistance, low thermal conductivity, good thermal insulation and soundproofing effects, low density, high specific strength, no deformation during long-term use, can be processed and spliced at will, 100% asbestos-free, does not produce toxic and harmful gases at high temperatures, and no smoke diffusion. It is a very suitable core material for fireproof soundproof doors and is an environmentally friendly building material.
This core material has been widely used in the core materials of mid-to-high-end fireproof soundproof doors in various buildings, with a fire resistance limit of up to 90 minutes, and even over 120 minutes. The products have been exported to the United States, Canada, Japan, and other countries, receiving unanimous praise from users.
