Three Ways to Heat a Floor

Dry modules, screed systems and thin electric systems — each built on a different XPS base. Here is how they compare, layer by layer.

Dry Module System (Water)

For renovation and timber floors. 30 mm grooved XPS modules with an aluminium diffusion layer take the pipe directly — no screed, no drying time.

Dry module system build-up
  • Build height: approximately 50–60 mm including finish floor
  • Walkable immediately after pipe installation
  • Best for: retrofit, timber construction, low ceilings

Screed System (Water)

For new builds. XPS insulation boards carry the pipe, then screed is poured over and the finish floor is laid on top.

XPS insulation boards for screed system
  • Build height: approximately 80–100 mm including screed
  • High thermal mass — slow, very even heat release
  • Best for: new build, heat pump systems, large areas

Electric Thin System

Heating cable or mat laid over high-density XPS, then self-levelling compound and tiles. No pipework, no boiler.

Electric underfloor heating build-up
  • Build height: approximately 30–40 mm
  • Zone-by-zone control, ideal for single rooms
  • Best for: bathrooms, kitchens, small retrofit areas

Heat Pump Combination

Low flow temperature systems that pair our insulation boards with an air-source heat pump, buffer tank and manifold set.

  • Low flow temperature — 35–45 °C design
  • Insulation quality directly determines COP
  • Best for: energy-efficient new builds, EU regulations
