Holyoake IBD-FS fire seal curtain-type fire- and leakage-rated dampers are designed to maintain the fire resistance integrity of a wall where a hole is used to permit an air distribution system to function by enabling the passage of air, ducted or otherwise, while minimising the impedance of fire and/or smoke and other toxic gasses.
The arrangement of interlocking galvanised steel blades and stainless steel side seals, mounted in a galvanised steel guide channel frame, reduces space requirements and makes installation in ductwork easy.
