      • Twice as strong as competitors 100 kPa Overfloor, Overlay and Floating floor boards

  Laminate and engineered wood can be laid directly on top, while carpet, vinyl and luxury vinyl tiles require an intermediate layer. The recommended maximum linear loop length for a 16mm board is 60m. The recommended maximum linear loop length for a 20mm board is 100m.

Beware when comparing Overfloor boards - although they may all look similar make sure you check the tech spec to ensure it's the correct strength for your desired finish.

Aluminium thickness	Board heat up speed	Heat output Under Wood, Laminate or Engineered	Heat output Under Carpet
Thick	Super Fast	100w/m²	80w/m²
Thin	Fast	60w/m²	55w/m²
Budget	Slow	40w/m²	35w/m²

Input temperature used in the above table is 40°c A micron is simply a measurement of thickness where 1000 microns is equal to 1mm. 100 Microns is a medium thickness foil covering giving reasonable performance. Suitable for New Builds & renovations with good insulation where rapid response is not required.

Please note: Output and system performance is dependent on insulation standards and environmental conditions.
