Application

Independent dry linings. Suitable for public buildings where dry construction methods are used.

Description

Independent, metal stud lining system based on 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


Features and benefits:

  • Homogeneous fibre-reinforced gypsum board with paper fibres and additives of non-combustible fibres with inherent moisture resistance.
  • Complies with the highest European building material class A1 (EN 13501-1).
  • Provides even more efficient and slimmer components in fire protection than the well-known fermacell® fibre gypsum board.
  • Installation is just as quick as the original fermacell® fibre gypsum board.
