Acoustic doorsets are installed in a similar
manner as normal
timber doors. Doorsets are supplied at a
moisture content of 6-12%
and should not be brought on site until
conditions are suitable. Wet
trades should be complete and the building dried
out and brought to
normal working room temperature. DO NOT
build-in or install
frames as first fixings.
1. Check the sizes of the doors,
the frames and the openings prior
to starting installation. Only skilled
tradesmen should undertake
installation as correct fitting of door/frame is
2. Frames should be fitted to the
supporting structure using steel
fixings at 500mm maximum centres and starting no
100mm from the base and head. The fixings
should be appropriate
for the supporting construction and sink into it
by a minimum depth
of 50mm. It is recommended that fixings
should be staggered down
each jamb with one fixing behind each hinge and
the others behind
the stops. Doorsets should have gaps of up
to 5mm between the
frame and the supporting construction stuffed
with mineral wool and
fully filled to a depth of 30mm on both faces
with a suitable mastic.
3. The weight of acoustic doorsets
are heavier than would normally
be handled by one person. All doors should
be handled by at least
3 people. All doors should be stacked on a
flat level surface with a
minimum of 3 equally spaced bearers. Doors
must not be double
stacked on top of each other.
4. Decorative veneered doorsets
should be protected from strong
light in order to prevent discolouration.
Full installation instructions
are supplied with each doorset delivery.
All acoustic doorsets should be installed in accordance with
All necessary hardware and accessories for a complete job

under standard occupancy conditions from 10oC to 20oC and
not more than 75% relative humidity in an enclosed building.
