By laying insulation material between the floor and the Amorphous Ribbon heating mats, the heat generated by the system is forced upwards through the floor covering. This ensures the rooms ambient temperature is reached quicker and more efficiently, thus reducing the “on” time, and providing considerable savings on energy costs.

Accolade’s flexible insulation

Accolade’s flexible insulation is 6mm thick and constructed from polyethylene foam. The cross-linked, closed-cell structure provides excellent physical and mechanical characteristics and is ideal for use where carpet, laminate, wood or engineered board will be laid above the Amorphous Ribbon system. Flexible insulation can be laid onto the base floor "floating" (not secured to the base) or held in place by tape and is supplied in rolls 10m2 (1.0m x 10m) or 20m2 (1.0m x 20m) long.

Accolade’s Solid board insulation

Recent improvements in manufacturing technology now allows us to supply solid board insulation at just 7mm thick and still have better thermal efficiency than it's thicker (10mm) predecessor! These are supplied in 1200mm x 600mm (0.72m2) boards. Made from extruded polystyrene it is ideal for insulating floors where ceramic, slate, stone, marble, vinyl etc will be laid above the Amorphous Ribbon system. Solid board insulation must be secured to the base floor using a flexible tile adhesive. A high mechanical strength to weight ratio gives excellent spanning capabilities and can support weights of 30 tonnes per m2.


Accolade’s insulation materials are supplied with the express purpose of:

  •     Deflecting any heat generated by the UFH system upwards into the room.
  •     Improving heat up times of the system.
  •     Reducing the power required to achieve a given temperature.
  •     Affording protection to the heat mat from objects such as nails, screw heads etc.
  •     Maintaining the manufacturers warranty through compliance with the recommended method of installation.
