Thermal upgrading system for concrete decks.

Jump to:
+44 (0)800 145 6033


Designed to be fixed to the underside of floors (generally concrete) to achieve specific U-values required. The boards can be fitted direct to the underside of a floor or to a supporting framework where the surface is uneven or otherwise unsuitable for direct fix methods. It can also be used to upgrade the thermal performance of masonry walls.


Thermal upgrading system for concrete decks that offers a solution to the increasing requirement for thermal upgrading of semi-exposed concrete decks both in the conversion and refurbishment of existing and new building constructions.

Features and benefits:

  • Premium thermal performance.
  • High dimensional stability.
  • Moisture resistant.
  • Fast track, dry construction.
  • BBA approved.
  • Effective for building lifetime.
  • Class 0 fire rating.
  • Bevelled edges.
  • A+ Green Guide Rating (BREEAM).

Technical characteristics:

  • Density: Calcium silicate: 1300 kg/m³; Phenolic: 50 kg/m³.
  • Mass: Calcium silicate: 8.3 kg/m² (6 mm thick); Phenolic: 4 kg/m² (80 mm thick).
  • Flexural strength: 10.5 N/mm² (calcium silicate).
  • Moisture movement: ≤0.15% (calcium silicate, 65% RH to saturated).
  • Thermal conductivity: Calcium silicate: 0.35 W/m·K; Phenolic: 0.02 W/m·K (˃45 mm thick).
  • Water vapour resistance (to BS 4370): ˃100 MNs/g (phenolic).
  • Compressive strength ˃100 kN/m² (phenolic).
