rock wool cavity insulation

Rock Wool Board has a light weight, the coefficient of thermal conductivity is very small, good elasticity, not easy to burn, not easy to rot, strong chemical stability, but also has a better sound insulation properties. 

Because its raw materials used is natural rock, so it has a strong high temperature resistance in case of unfortunate fire. It will form a fire barrier, can effectively avoid the spread of fire tendency. 

Production of rock wool board cotton filaments are generally characterized by slender and flexible. Coupled with its low thermal conductivity, it has a superb thermal insulation effect. It has the performance of absorbing noise. Based on its physical properties, the rock wool board achieves the characteristic of absorbing sound to reduce noise.

At the same time, rock wool also has a simple construction, low comprehensive cost, non-toxic, odorless, non-radioactive pollution, harmless to the environment and the human body, with good environmental protection benefits and so on. In particular, the fire retardant safety is particularly good, the user is assured. Because it belongs to the fireproof class A non-combustible products, it can be widely used in dense housing, public buildings, large public places, flammable and explosive places, and places with strict requirements for fire prevention, and improve the standard of architectural fireproofing at the same time of heat preservation.

In the construction process of building projects, the exterior wall insulation system must be good, the construction process and the choice of materials are very important, the exterior wall insulation system at the same time but also play a role in the protection of the building, the performance of the material is the most important, only the rock wool such materials applied to the building of the exterior wall insulation system, to be able to protect the building's safety and thermal insulation and fire resistance, etc.
