Gyptone BIG Installation Manual
Design and technique
Product description
Gyptone BIG is a gypsum based acoustic ceiling
with high design value since no joints are visible.
The ceiling can be used for many applications like
schools, oces and commercial settings. Gyptone
BIG is screw mounted and non-demountable. The
product is subject to full recycling as raw material
for new plaster boards.
Gyptone BIG is available with perforated and
non-perforated surface. Thickness is 12.5 mm
and the format is 1200 x 2400 mm and
900 x 2700 mm.

The plasterboard surface is subject to paint
treatment after installation. Treatment is to
be executed with a roller as spray painting will
impair the acoustic performance. Joints are to
be filled, sanded and painted, c.f. page 3.
Plenum height
Minimum and maximum plenum heights with GK
system in one level is to be found on page 7.
Fire resistance
A2-s1, d0.

positioning of metal framing, ceiling boards and
a potential perimeter. Mark and fix suspension
straps with appropriate fixings. Use 2 pcs of clips in

Installation manual
Use a QSTR 25 screw when mounting Gyptone BIG
Boards. Distance from screw to corner is 50 mm and
from screw to edge 15 mm. Distance cc between
screws 200 mm. C.f. page 6 for additional positioning
of fixings.
All board joints are to be jointed with adequate filler.
Apply first a layer of Gyproc ProMix Joint or the like
in the tapered section. Subsequently adding a paper
reinforcement in the wet filler. Light sanding (grain
100-200) when cured. Apply a layer of filler Gyproc
ProMix Finish or the like. Light sanding when cured
until level with board.
Painting of Gyptone BIG is to be done with a short
haired mohair roller to avoid excessive paint into
perforation. Spray painting is not to be used as paint
will impair the acoustic tissue thus degrading the
acoustic properties. Gyptone BIG is to be primed and
painted twice.
Filling of screw heads with Gyproc ProMix Finish or
the like in two rounds finished by a light sanding until
level. Tip: Use a piece of plastic wiht a circular hole as
a mould.
