Description

Extruded polystyrene (XPS) thermal insulation boards for use with ThermoSphere underfloor heating.

Features and benefits:

  • Can be cut with normal hand tools.
  • 100% moisture and rot proof, suitable for use in bathrooms and wetrooms.
  • Helps prevent mould growth from moisture in bathrooms.
  • Can be installed on walls and floors.
  • Reduces heat loss into the substrate and increases heat-up times.
  • Improves the efficiency of underfloor heating by more than 50%.
  • Fibre reinforced for improved lateral stability flexural strength.
  • Coated boards improve lateral and flexural strength of timber floors.
  • Lighter and stronger than ply.
