 Filling
Fill the space between the damper and the wall using Fire Batt
(Weichschott) sealing made from two rock wool panels with mini-
mum thickness of 50 mm and minimum density of 140 kg/m³.
The panels must be covered on both faces of the wall with endo-
thermic varnish type PROMASTOP E PASTE or HILTI CFS-CT (mini-
mum thickness of 1 mm) and with an internal perimeter sealant type
PROMASTOP E PASTE or HILTI CFS-S ACR (minimum thickness of 1
mm).
