Technical information floor boards

Years of delight with a floor begin with a good preparation of the space where it will be laid, the clean execution of the laying work and proper subsequent cleaning and care.

Preparation

The right room-climatic conditions are particularly important, as are the properties of the ground.

Humidity

Important in Winter: Keep humidity at 40-50% 

Keep an eye on humidity. If you don't humidify, humidity in many rooms can drop below 30-35% during the heating period. Too low of a humidity can lead to drying up of the wood and cracks in the floorboards. pur natur assumes no liability in those cases. We recommend humidifying the rooms with humidifier, so that humidity is kept at 45-50%.

Information

All pur natur boards are marked with the CE stamp in accordance with the DIN EN 14342, and fundamentally suitable for underfloor heating.

Solid boards with a thickness of 35mm and a width of 400mm are automatically suitable for underfloor heating due to their material strength. We will gladly provide you with advice on this subject.

3-layer boards in widths of 400 and 450mm can be used without harm with underfloor heating.

In all cases, please pay attention to the room-climatic conditions.

Floor construction

Boards glued onto the screed across their full surface

pur natur boards can be glued directly onto the screed. Especially in the case of new constructions, this is one of the most common choices for laying the boards. The direct gluing onto the screed makes it possible to use underfloor heating (heated screed) without any problems. A further advantage is the relatively low construction height on the screed.

Boards nailed onto the screed

 

Screwing the boards onto the screed is a laying variant that is not common in the case of new constructions or old construction renovations, but is fundamentally possible. For a proper laying it is necessary to screw through the boards and “hide” the drill/screw holes with special Douglas fir or oak plugs.

Invisibly screwing the boards onto a joist cross bracing

Laying the boards on a “joist cross bracing” is recommended for new constructions or substructures in places where a certain height bridging in necessary in the substructure (as of 100mm UK height). The construction with two wooden joist levels also makes the use of two different insulation materials possible, for example filling/panel material, which in turn means an optimal use of the hollow space in combination with heat and/or noise insulation.
