Fireproof Rockwool Board External Wall High Temperature Resistant
Product overview
The rock wool board product has high strength and good elasticity. The rock wool board with certain pressure resistance and pleating treatment has large drawing strength, is not easy to rise, and greatly improves the firm durability.With high compressive and tensile strength,excellent hydrophobic and moisture proof property,it can be applied on all kinds of solid wall substrate such as masonry and concrete,and both suitable for new/expansion project and retrofitting project of existing buildings.When a fire breaks out, the product's class-A non-combustibulity and good anti-high temperature shrink ability can maintain the stabiliy of the system structure.
1. Insulation performance: The thermal conductivity of cherry rock wool under normal temperature conditions (about 25 ° C) is usually between 0.03 ~ 0.047W / (m & middot; k).
2. Combustion performance: The burning properties of rock wool products depend on the amount of flammable binder.
3. Sound insulation performance: Rockwool has sound insulation and sound absorption performance. The sound absorption mechanism is that the product has a porous structure. When the sound wave passes, friction is generated due to the flow resistance, so that part of the sound energy is absorbed by the fiber, which hinders the The transmission of sound waves.
