Laminate and engineered wood can be laid directly on top. Tiles can be fixed to the boards using Mapei or Ultra approved adhesive (when using Ultra's method just prime the aluminium first.)

If you wish to carpet or lay vinyl on the roll a suitable backer board will need to be laid on the Overfloor boards. The recommended maximum linear loop length for a 16mm board is 12mm pipe at 60m. The recommended maximum linear loop length for a 20mm board is 16mm pipe at 100m.

Beware when comparing Overfloor boards - although they may all look similar make sure you check the tech spec to ensure it's the correct strength for your desired finish.
