FK90K fire dampers
Installation in metal stud walls (3c) Sliding ceiling connection
All dimensions in mm
•
Installation subframes ER5 must match the web
height S I of the metal studs I, whose profiles should
have the corresponding stud profile depths.
•
The metal studs II contain a recess that is framed by
the wall profiles. Accordingly, the strips of wall clad-
ding material (e.g. plasterboard) attached to the ceil-
ing are severed and sealed at the front (section C-C).
•
The profiles surrounding the recess on the metal
studs II have reveals made from 30-mm-thick calcium
silicate boards. These are guided up to the ceiling
leaving a gap f for the drop (section B-B) and attached
to the metal stud profiles using drywall screws at
≤ 200 mm centres.
•
If the metal studs have claddings on both sides, then
the sliding joint for the connection collar of the installa-
tion subframe ER5 will lie between cladding I and the
reveal attached to cladding II (section B-B).
•
Joints should be filled as usual for this type of wall.
