The panels are manufactured for use with 12 mm pipe and centres at 150 mm. The panels must be laid onto a flat and level subfloor, which can either be concrete or timber based. Over a concrete floor we recommend laying the panels over a combed layer of flexible tiling adhesive. For timber floors we recommend securing with screws and washers.
Tiles and wood flooring can be laid directly over this system Other finishes such as carpets or vinyl will require a 9 mm board layer, prior to the finish layer.
