Abstract (en)
[origin: WO2006075045A1] A smoke damper is disclosed comprising a substantially rectangular frame installable in a ventilation air duct, the frame having pivotally mounted thereon at least one rotatable slat (2), the slat(s) being rotatable with the help of a separate mechanism by about 90° between an open position and a closed position, the slat having a first long edge (2') and second long edge (2") as the opposite slat edge relative to the first edge, and the slat further having attached thereto an elastic seal (3) and an intumescent sealant (4), whereby the elastic sealant (4) is attached at least onto the first long edge (2') of the slat so as to extend substantially over the entire length of the slat edge. The invention is implemented by way of attaching the intumescent sealant (4) at least onto the second edge (2") of at least one slat (2) so as to extend substantially over the entire length of the slat edge and that the intumescent sealant (4) is covered by a continuous-section strip (7) capable of moving outward from said long slat edge under the swelling action of the intumescent sealant.
