Selecting the right species

The relative humidity of a normal domestic environment is likely to range between 35% and 65% over a yearly cycle, and wood floors will shrink and swell in response to these conditions.

By selecting an appropriate species of timber, you can control dimensional movement occurring over the lifetime of the floor. For most domestic environments, species with medium movement characteristics will give you a floor with acceptable levels of movement. 

Installation over under floor heating

For installations over under floor heating, it is essential you limit the selection of species to those with small movement characteristics. Maximum board widths of 75mm are normally recommended for under floor heating installations, although wider commercial products are becoming available which may require special precautions to avoid in-service movement. You must also ensure that the moisture content of boards intended for under floor heating installations is between 6% and 8% when the floor is laid.

Wear resistance

Different species of flooring will provide different levels of wear resistance and you must give this some consideration for floors which are subjected to different levels of trafficking.

Thickness of boards

When fixing wood strip or boards onto support battens or joists, you must select a thickness of board which is appropriate to the span of the batten or joist in order to avoid deflection and squeaking of the floor.
