MOUNTING A VALVE OUTSIDE THE FIREWALL :
In general, care is taken to install the fire dampers in a wall so that the fire damper blade is located in the thickness of the fire wall when in closed position
Practically, this solution is not always possible and we must therefore resolve to move the fire damper outside the firewall, which requires extending the firewall to the flap blade.
This is carried out by carrying out the fire protection extension, using the “PROMAT” panels on the basis of the fire test reports of metal ductwork. This is one of our specialties in 60- and 120-minute fire resistance.
Our team is at your disposal to carry out site visits on a case by case basis to give you a price adapted to each case.
