Tile Backer Board Insulation

RRP From: £15.83

Tile backer insulation boards are designed for use directly under tile and stone floors. When used with underfloor heating the board greatly increases the response rate and overall efficiency of all under floor heating systems. These boards are especially effective when installed over a concrete sub-floor. Each board is 1200 x 600mm (0.72sqm).

If applying boards to a wooden sub-floor or wall joists then we can also supply the cement board washers.

IMPORTANT! All our electric underfloor heating systems must be run via suitable 'Fused Spurs'. Please consult an electrician if in doubt.

Underfloor Heating Tile Backer Board Insulation

We recommend insulating your sub floor both wooden and concrete sub-floors, however this is especially necessary on a concrete sub-floor with underfloor heating installed. This is because the concrete will drain the heat from your underfloor heating downwards. This can be avoided with our low-cost Tile Backer Board which will increase the efficiency of your underfloor heating system and reduce your overall heating bill. The tile backer boards measure 1200 x 600mm.
