Mineral Fibre External Wall Insulation Systems

PermaRock Mineral Fibre external wall insulation systems are fire-safe, high performance thermal insulation systems that are extremely versatile and particularly suited for application to residential buildings, hospitals, schools, and public buildings where the highest levels of fire resistance and non-combustibility are required.

The systems are also recommended for multi-storey, high-rise buildings and, in Scotland, any building that is less than 1m from a boundary.
