Fire damper - FDML
TPM 130/17
1 FDML
2 Solid wall construction
Weichschott system HILTI***
3
Mineral wool board - min. density 140 kg/m³ (HILTI CFS-CT B 1S 140/50...)
4 Fire stop coating - th. 1 mm (HILTI CFS-CT...) - coating is overcoated on the support construction and on the damper casing/duct
5 Fire-resistant mastic - (HILTI CFS-S ACR...) fill the gap from both sides of the fire separation construction and around the perimeter of
penetration and damper casing
6 Fire-resistant cover boards - only if one side of the damper is in line with the surface of the construction and the other side extends more
than 25 mm from the construction - (Promatect-H...) min. thickness 15 mm - connect the boards together with screws
In solid wall construction - Weichschott system

* In case with connected duct and with forced air flow
** In case without connected duct with grilles on both sides and with natural air flow
*** HILTI system can be replaced by a similar system with the same or higher
thickness, density, fire reaction class, tested according to EN 1366-3.
