Why our Foam Cored underlay is so special

We insist on extruded foam (not styrene balls)

Why density is important.

Our Underlay Wet floors and Tile Backer Boards are made from extruded foam (not agglomerated styrene particles). As a result the density weight loading is 30 tons per sq. metre. This may sound a lot, but gives us the confidence to permit use of tiny (25mm x 25mm) mosaic tiling. The maximum point load per tile is therefore 18.7Kg per 25mm x 25mm tile and customers can have total peace of mind that the tile will not sink into the underlay.

Note: Beware of competitor products with densities of 12 – 24 tons per sq. metre.

Extra Tough Skin

Each side of the former is layered with a reinforcing mesh and covered in a continuous layer of polymer cement.
