Fire-teK WM 908 GGA

Fire-teK WM 908 GGA is a mineral wool wired mat with bio-based formaldehyde-free binder, with tear-resistant glass fibre reinforced aluminium foil on one side that has been especially designed for fire protection on round ventilation ducts. Fire resistance: El 30 (ve ho i↔o)-S / El 60 (ve ho i↔o)-S

Specification
  • FIRE PROTECTION WIRED MATS
    KNAUF INSULATION FIRE-TEK WM 908 GGA

    Type of Insulation:
    Mineral wool wired mat for the fire protection and thermal insulation of round air ducts.
    The wired mat must have certification and CE marking in accordance with EN 14303.

    Facing:
    The wired mat shall have aluminium foil between the mineral wool and the wired mesh.

    Description:
