Installation Guide

WOODEN SUBFLOORS
The wood moisture content of
a wooden subfloor should not
exceed 14 %. Your supplier
can carry out the required
measurements using an wood
humidity meter. You must first
check the floor for loose parts
and tighten the same in place
(see 5). You may level the floor by sanding it down or
installing a chipboard sheet. The wooden subfloor should
have an underlayment. A 3 mm underlayment will be
adequate from the technical point of view but a 7 mm
natural board fibre plate has a better levelling effect and is
recommended for floors with slight differences in height.
Do not lay the panels if the crawl space is wet. Always
make sure there is sufficient ventilation to allow the
subfloor to ‘breathe’.
UNDER FLOOR HEATING AND COOLING
If you want to install a wooden floor on top of the under
floor heating and cooling, there are certain guidelines you
must follow. It is important to know what type of system is
being used, but also the type of subfloor and the type of
parquet. Beech, Ash, Maple and Jatoba are wood types that
easily warp and, therefore, are not recommended for use in
combination with under floor heating or cooling. The
guarantee will not apply when these wood types are
installed in combination with under floor heating or cooling.

REQUIREMENTS WITH REGARD TO NOISE
REDUCTION
There are situations where a sound-damping subfloor is
required. Your supplier has various kinds of underlayment
in its range that meet these requirements. Ask for the test
report.
MODIFICATION OF DOORS Check
whether your doors can open and close
with the combined height of the
flooring and your subfloor if any. If not,
you
may modify (shorten) your doors
according to the changed situation
(see 6).
DILATATION
Movement joints should be
installed if floors are more
than 10 m long or more than
6 m wide, as well as near door
openings, between rooms,
at turns in passages, etc. (see
7). These movement joints
may be finished using specially
developed dilatation joint profiles.
There should be an offset of at least 40 cm between the
cross-cut ends of the floor panels in consecutive rows.
(see 8).
FLOATING INSTALLATION OF ENGINEERED
PLANK FLOORING
The panels are laid ‘floating’ by gluing the panels
together using water-proof PVAC wood glue (D3 wood
glue).
1. After the underlayment has
been installed, the next step is
to start installing the panels in
a corner of the room which is
immediately visible when entering
the room (see 9). First calculate
the number of tracks that you
will be laying. You will obtain best results if the first and
the last track are of approximately the same width. Now,
lay the first panel with the groove of the length facing the
wall. Usually, the panels are laid lengthways in the house
(in the direction of the light).
2. An expansion joint of around
the thickness of the floor should
be installed all around the floor.
Place a spacer block at every 40
cm (see 10). Remove them 24
hours after the floor has been
laid.

EXPANSION GAP
If the humidity level and
temperature change, the
floor may shrink or expand to
some extent. For this reason,
an expansion gap should be
=
D
maintained with
respect to all
fixed boundaries such as: walls,
thresholds, columns and central
heating pipes, which is as thick as the floor itself (D)
