Marmox Board 20mm (1250 x 600mm)

Marmox Tile Backer Boards are ideal for two primary purposes; as a superior waterproof surface to fix wall or floor tiles and as a first class heat insulation for underfloor heating systems. Marmox insulation boards are particularly suited to underfloor and under tile heating applications. Installation below underfloor heating systems on an existing un-insulated concrete or timber sub-floor will greatly reduce heat up time and running costs.

• Marmox boards are waterproof and dimensionally stable (unlike plywood)
• Fix with SUPA PRO screws and SUPA PRO Tile Backer Board washer to studwork walls or wooden floors
• The 600x1250x20mm board weighs only 2.48Kg.
• Excellent sound insulation: impact sound is reduced by 25 decibels for Marmox boards.
• Cuts with a knife.
• Excellent for wet rooms.
• Designed to take the heaviest wall tiles, unlike plasterboard.
• Excellent heat insulation with U valuesas low as 0.54 making them ideal for use as a thermal barrier with under floor heating.
