Insulation board (Tiles) Hardfoam ISO64 6, 10 and 20 mm

For example, for a 3 m2 bathroom: 3 m2 / 0.72 m2 = 4.1 insulation boards needed = 5 pieces.

The pressure-resistant Quality Heating ISO-64 insulation boards allow the floor to warm up faster with an efficiency increase of 33%. Specially developed for under tile floors. Even if you have a limited build-up height, the ISO64 insulation board from Quality Heating offers a solution. With the ISO64 you increase the efficiency and response time of the underfloor heating mats. These properties result in lower energy consumption. The hardfoam ISO64 is coated on both sides with a coating incorporating a special mortar application into the board's fiberglass structure.

Installation ISO-64 Hardfoam boards

If the board is installed on a wooden subfloor, it is recommended to both glue and screw the boards. When the board is fixed to a concrete/cement screed, gluing alone is sufficient. A tile adhesive can be used for this.

The ISO-64 insulation board is available in the following dimensions:
1200 mm x 600 mm format and thicknesses of 6, 10 and 20 mm. Area per board 0.72 m2.
