Fastwarm® Thermal Insulation Boards For Concrete Sub-Floors

Fastwarm® thermal floor insulation boards are designed to meet the very specific needs of the underfloor heating industry: capable of supporting thin screeds and tile floors directly. Fastwarm® thermal insulation boards' unique properties of high strength and low thermal conductivity make them the ideal thermal floor insulation for all electric cable or hot water underfloor heating systems.

Fastwarm® insulation boards are designed for use over solid concrete sub-floors and cement screeds. For wooden sub-floors use Fastwarm-Xtra insulated tile-backer construction boards - for more info on Fastwarm-Xtra click tile-backer boards.

Fastwarm® thermal insulation boards are manufactured from extruded polystyrene foam, produced without the use of CFC or HCFC blowing agents, have zero Ozone Depletion Potential (ODP) and are fully recyclable.

Physical Properties Of Fastwarm® Insulation Boards 

Fastwarm® thermal insulation boards have high thermal insulation properties, high compressive strength (30 tonnes per m² ) capable of supporting long term static loading, waterproof, rot resistant, light weight, easy to handle, easily cut and shaped with a sharp knife, available in various depths from 6mm to 80mm and low cost.

Using Fastwarm® Thermal Insulation Boards

Fastwarm® thermal insulation boards have a specially prepared surface to accept all water based floor tile adhesives and will form a strong bond without the need for further priming; cement screeds can be poured on top in the normal way.

Thermal energy moves from a higher temperature to a lower one, the bigger the difference the faster the transfer.

The thicker the thermal insulation the slower the transfer.
