We firestop the gaps around fire dampers, both circular and square, installed in rigid and flexible walls and floors.
We seal gaps around fire dampers and shut-off dampers used in ventilation and air-conditioning systems. Depending on the solution used, these include rectangular dampers, circular dampers, and single-blade and multi-blade dampers.
The work involves properly filling and sealing the space between the fire damper and the wall or floor, using methods that comply with the technical requirements of the system concerned.
In every case, we determine the sealing method based on the technical documentation and the manufacturer’s DTR (technical and operating documentation) for the fire damper used, taking into account its type, design, dimensions, installation method, the type of wall or floor and the required fire resistance class.
Because we select the method case by case, we can properly seal the gap between the damper and the wall or floor, maintaining the required fire protection performance and compliance with the system solution used in the building.
