Why our Foam Cored underlay is so special

  • Made from extruded foam (not agglomerated styrene
    particles).
  • Density weight load of 30 Tons per square meter.
  • Tiny 25mm x 25mm tiles may be used.
  • Point loading per 25mm x 25mm tile is 18.7kgs.

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.
