Note
Fire walls are fire-resistant walls that keep their stability and enclosing function under the influence of fire
because they are especially resistant to dropping constructional components.

Knauf Fire Walls
Construction and application, surface treatment
W13
Construction
Knauf Fire Walls consist of a single metal stud
frame. Two or three layers of Knauf boards are
screwed to both sides of the metal framework.
A metal sheet is installed below the top layer of
the cladding. Insulation material according to
the requirements of building physics can be installed
in the partitions cavity.
Settlement joints have to be taken over into the
construction of the Fire Walls. For continuous
walls use control joints at approx. 15 m.
Application
Metal stud frame
● Apply Acoustical Sealant (two strings) or
Sealing Tape to backside of runners for the
connection of fl anking constructional components.
For sound protection requirements seal
up carefully with acoustical sealant according
to DIN 4109, supplement 1, chapter 5.2; porous
sealant strips like Sealing Tape are usually
not suitable in this case.
● Fix perimeter runners (UW runners at fl oor
and ceiling, CW studs at walls) with suitable
dowels to fl anking components, e.g. Ceiling
Steel Dowel with reinforced concrete ceilings
(use and application according to Construction
Supervisory Permit Z-21.1-1519) and nailable
plug with masonry. Spacing of dowels
0.5 m at ceilings, 1 m at walls (at least 3 fi xing
points).
● For W131 use dowel with washer Ø 30 mm, t
≥ 2 mm for connections to ceiling and fl oor.
● Install CW studs at a spacing of 31.25 cm in
UW runners, aligne, fi x with two metal rivets
(≥ 3 x 8 mm) each to bottom and top.
Cladding
● Two layer cladding of W131 with horizontally
applied Knauf Solid Board 20 mm + vertically
applied Knauf board GKF 12.5 mm or with
three layer cladding with vertically applied
Knauf boards GKF 12.5 mm.
● Two layer cladding of W132 with horizontally
applied Knauf Fireboard 15 mm.
● Spacing of screws of fi rst layer 75 cm, of
middle layer 50 cm and of top layer 25 cm.
● Displacement of joints according to DIN
18181.
● Metal sheets as plates or coil material, 0.5
mm thick, install horizontally under top layer,
overlap all joints at least 10 cm. Screwing with
Drywall screws (W131 three layers: TN 3.5 x
45/ W131 two layers and W132: TN 3.5 x 35)
only to fi x for installation, remove while applying
the boards.
Vertical joints of metal sheets only on studs.
Jointing
● Filling and covering of joints should only take
place after the boards have been allowed to
rest in the given humidity and temperature zones,
and no more longitudinal changes can be
expected, i.e. expansion or contraction.
● Joints should be filled at a minimum temperature
of 10°C.
● In case of mastic asphalt screed, fill in joints
after screed has been applied.
● Cover all screw heads as well.
● For double layer cladding, fill in joints of first
layer, smooth joints of second layer.
W131: Fill in joints with Knauf Uniflott without
using tape. If using tape, fill in with Knauf Fugenfüller
Leicht or with Ames machine and Knauf
Jointfiller-Super.
Recommendation: Fill in and tape cut edges of
visible layers no matter which filling material is
used.
W132: Hand filling with Fiber Glas Joint Tape
and Knauf Fireboard Filler.

Surface treatment
Use a primer on Knauf Boards before coating or
painting them. Ensure that the primer and the
coat or paint are compatible.
After wallpapering of paper and fi ber glass wallpapers
and the application of resin / cellulose
plasters quick drying must be assured through
adequate airing. The following coats can be
used to cover Knauf Boards:
● Plasters: Knauf structured plasters, e.g. resin
plasters, thin plasters, entire area smoothing
like e.g. Knauf Board-Finish, mineral plasters
in connection with paper taped jointing.
● ceramic tiles
● Wall Papers: paper-, textile and synthetic wall
papers. Use only adhesives made of cellulose
according to „Merkblatt Nr. 16, Technische
Richtlinien für Tapezier- und Klebearbeiten“,
Frankfurt/Main 2002, released by Bundesausschuss
Farbe und Sachwertschutz.
● Coats: Washable and abrasion-proof emulsion
paint, multicolored (rainbow) emulsion, oil
paint, matte-fi nish lacquer, alkyd resin paint,
polymer resin paint, PUR lacquer, or epoxybased
lacquer, according to intended use or
as required.
● Alkaline coats such as lime, water glass colors
and silicate-based paints are unsuitable
for gypsum board surfaces. Silicate-based
emulsion paints may be used after referring to
the manufacturer’s recommendations and following
the stipulated guidelines closely.
Gypsum board surfaces that have constantly
been exposed to light without any protection can
develop yellowing agents that show up despite a
coat of paint. Therefore a trial coat is recommended
that will extend across several boards including
all joints. Yellowing can, however, be successfully
avoided only by using a special shielding
primer.
