correct fire damper upgrade with PA board

fire damper upgrade

  • fire dampers ≤ 600x300mm, upgrade towards fire compartment:
    – fire damper support onto floor, not onto wall
    – in case of wall deformation, adjacent joints fire damper – wall remain intact
    – no extra expansion unit required
  • constructive element:
    – flexible walls ≥ 100mm
    – rigid walls ≥ 100mm
    – view installation in walls
  • fire resistance acc. EN 1366-2:
    – EI 60, principle configuration
    – smoke control acc. EN 1634-3
  • easy + correct upgrade:
    – always apply acc. DoP No. CPR-14/0260-board
    – support fire damper onto floor with M8 bolts

    – cut PA board to size:
    1 layer PA board for cladding towards fire compartment
    – 2x PA board strips for a tight-fit positioning in opening

    – ‘butter’ all cross cut edges of PA board + opening with PA coating
    – position PA board tight-fit + butt joint
    – use PA spirals for board-to-board connections
    – seal off adjacent joints with 5mm Acrylic or PA sealer
