Bearing floorboards

do it easy

It is recommended that joist layers should be sized in accordance with  NBI’s Joisting Table for high rigidity. The Joisting Table for minimum rigidity should only be used in secondary spaces where there are reduced requirements for comfort. The joist layer must be levelled and carefully installed with exact centre-to-centre spacing. All free  board and slab edges must be supported. Before embarking on installation, the site must be closed, ventilated and the heating functioning.

The  boards must be installed in direct connection with the levelled joist layer with the stamped side up. The  boards must be installed lengthwise on the joist layer.  The boards are screwed or glued to the joists and glued at all joints. This makes the floor more rigid and reduces the risk of squeaking when the joists dry. The screws are sunk 2-3 mm into the board. Forestia 18 mm Floor requires the use of a rigid covering floor, such as a parquet floor.

Floor for larger projects

Forestia Project floor

Areas of use: 22 mm Extra – platform floor. Bearing underlay on wooden beam battens (Climate class 2).

Forestia Project Floor P5/P6 are large format floorboards which are suitable in prefabricated elements or onsite built
platform floors in major building projects. The boards are supplied in a thickness of 22 mm with tongue and groove on
the length sides. Width 1200 mm, length from 3.0 – 4,2 m.

Forestia Project Floor Extra P5/P6 is intended as a free bearing underlay on a three joist layer of c/c 0.6 m. One can
count on a time saving relative to the installation of ordinary floorboards of approx 60 %. The large format also allows
for additional savings of 35-40 % on fastenings and glue consumption and leaves minimal stubs at building sites.
