Dry Installation
Wall Installation Using Mineral Wool and Cover Boards
1. The supporting construction opening must be prepared in a way depicted in the “Opening Preparation for
S-BM2 Installation” section (as per Fig. 1 and Fig. 2). Opening surfaces must be even and cleaned off.
The flexible wall opening must be reinforced as per the standards for plasterboard walls.
The opening dimensions are driven by the nominal dimensions of the damper with added clearance.
The opening will be with the dimensions of
W
1
and
H
1
2. Insert the damper as per the “Manipulation of S-BM2” section into the middle of the opening so that the damper
blade is in the wall. For damper widths greater than 600 mm, it is recommended to use a duct support inside
the damper during installation to avoid any damage caused to the damper housing by the weight of the filling.
3. Fill in the area between the wall and the damper with mineral wool (3) with a density of at least 100 kg/m
3
thoroughly but in such a way that will not deform the duct.
4. Close the gap between the damper and the mounting opening, use gypsum boards (7) with screws (8)
which fix the gypsum boards to wall.
5. All the gaps between gypsum boards and the wall and between gypsum boards and the connected ductwork
made of Promatect boards need to be filled with putty for gypsum boards (9; e.g. Rigips Super)
6. Check the functionality of the damper.
