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.
