III Floor heating
Installation over sub floor heating - some important issues.
Max allowed temperature on top of the wood floor is 27 °C.
Please note that normal loose carpets insulate i.e. increase the floor surface temperature
about 2 °C!
Do not install Beech/ Maple/Ash over floor heating, These wood species are, due to their
natural properties, sensitive to heat, which can cause joint openings, concave warping or
squeaking.
Important: Follow the heating regulation recommendations given by the system supplier.
Please note that a 0,2 mm PE-plastic film always must be placed on top of the construction
floor either made of cement screed /concrete, etc or also over wood!
Separate floor areas not having sub floor heating with expansion joints.
GBR has provides an english document “Wooden floors over under floor heating”.
This can be bought at GBR or downloaded from their homepage www.golvbranschen.se
D. Installation preparations
I. General
Measure the area to be installed and define the installation direction.
It is recommended to install the length direction of the planks parallel to the main light
direction. The board width of last row shall not be less than ca 50 mm, If so, adjust the width
of the first row to be installed.
When measuring take the free gap requirement of about 10 mm of the floor perimeter into
account. In narrow hallways, install the floor parallel to the length way.
II Floating installation
Your floor is made to be installed floating without glue:
Leave an open expansion gap of min 10 mm around the whole perimeter (use the
distance wedges), i.e also at pipes, stairs, columns, doorframes and thresholds. In
large rooms, calculate 1,5 mm / m floor around.
Install maximum 10 m length /width; over this: allow for an expansion gap, to cover
with a profile of wood or metal.
The floor must be able to move free – do not connect or install tight to any
construction part.
Rooms with off square areas like for example L-,F-, T-, U- shapes, separate the areas
with an expansion joint and especially always in door openings.
At any question contact your distributor for further information, installation at doors,
glue down, etc
Claims re visible defective floor panels must be made prior to installation.
Each board should be inspected to ensure that the quality is acceptable.
No claims relating to surface defects can be accepted after installation
