Application

  • Suitable for ultra low profile retro fit installations.
  • Suitable for use with wood and tiled floors.

Description

Fastwarm® Duo panels utilize high compressive strength through expanded polystyrene, with a high tech aluminium foil covering. This acts as a heat conducting surface to transfer the heat from the pipes to the finished floor above.


Features and benefits:

  • Provides ready-made pipe securing and spacing using pre-grooved insulated boards.
  • High compressive strength insulation, for the direct application of engineered wood floors.
  • Offers a combined floating floor and underfloor heating solution.
  • Typical outputs up to up to 76 w/m².
  • Available in two thickness 20 mm (for 16 mm pipe) and 16 mm (for 12 mm pipe).
