fire damper upgrade
deformation “proof”
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
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
