Backer Board PRO Tile Backer Board Insulation

Backer Board PRO Tile Backer Board Insulation is available in 6mm, 10mm, 20mm & 30mm depths and is designed to insulate and resurface walls and floors. These Professional Series insulation boards can be tiled onto, plastered over and also rendered. Perfect in wet room areas. Likewise very applicable if you have a wooden sub-floor, as the tile backer boards can be screwed directly to the wooden floor with cement board washers. In addition, the insulation boards can also be glued down with a flexible tile adhesive. Please note that the 6mm boards are not suitable for walls. In this case, 10mm or 20mm boards should be selected for walls in cases where tiles are being installed over the insulation boards. Please feel free to contact our technical department if you would like any further information on your specific project.

  1. Gary Stapleton

    I was so impressed at how quickly you turned my order around that I thought a personal
    “Thanks and well done” was in good order. I was pleasantly gobsmacked to find this order, placed only yesterday at one o’clock, being delivered to me this morning at ten thirty! Don’t know if that’s some kind of record but it speaks much of both your own service and the good working relationship you must have developed with your couriers. Enjoy a pat on the back from one satisfied customer at least..
    Very best regards…Gary.
