fermacell Firepanel A1

fermacell Firepanel A1

fermacell Firepanel A1 is a new dimension in fire protection for dry linings. The innovative development of the original fermacell Gypsum Fibreboard complies with construction materials class A1 (non-combustible).

A1 classification for linings are increasingly being specified throughout Europe for public buildings where dry construction methods are used. The reason is the harmonisation of fire safety tests and fire protection classifications, which have resulted in more stringent national requirements for construction materials and building elements. fermacell Firepanel A1 was designed specifically for these applications. A new formulation and the use of non-combustible fibres have made this possible.
