Render Insulation

Coverock R90

Coverock R90 product is a type of stone mineral wool that is specifically designed for use in External Wall Insulation (EWI) systems. It provides excellent thermal insulation, and once installed, it is well-suited for receiving both hand-applied and machine-applied, mesh-reinforced render systems.

In addition to its EWI applications, Coverock R90 can also be used for internal and external insulation of buildings, providing effective protection against heat loss, noise pollution, and fire protection. Notably, this product is classified as an A1 non-combustible material, which makes it a safe and reliable choice for a range of building insulation needs.
