Product Information

See our installation guides and download Factsheet F01P+ Wunda Rapid Response® Factsheet from our Support page

20mm boards require 16mm pipe using 150mm pipe spacings (100m total length)

Approved for Tiling directly onto using our approved methods - without the need for a backerboard*.

Thick Rapid Response Aluminium will give optimum system performance. Wundatherm underfloor heating boards are lightweight, super strong, easy to fit and designed to be fitted over any existing or new floor. No specialist tools are required, they can be simply cut to shape using a fine toothed saw or craft knife.

MAPEI, ULTRA and NORCROS approved for tiling onto- Using Mapei & Instarmac approved S2 flexible adhesive and primers please Refer to our Support page.

*Natural stone may require a backerboard- please call for details or refer to our Support page for specific details.

Suitable for Laminate, Wood, Carpet Vinyl and even Tiles. Quick to install using Wunda Spray contact adhesive ready for use straight away.

  • 20mm board uses 150mm pipe spacings with 16mm pipe at 100m total pipe lengths
  • Mapei & Instarmac approved for tiling directly onto using specified methods, please refer to our Support page.
  • Easy to cut to shape with basic tools
  • Eliminates the moisture, weight, mess and lengthy drying times of a screed Underfloor system

Laminate and engineered wood can be laid directly on top. Tiles can be fixed to the boards using Mapei or Ultra approved adhesive (when using Ultra's method just prime the aluminium first.)

If you wish to carpet or lay vinyl on the roll a suitable backer board will need to be laid on the Overfloor boards. The recommended maximum linear loop length for a 20mm board is 16mm pipe at 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.

Rapid Response® and maximum heat is only possible with Wunda's patented board.

Rapid Response® in all property types. Suitable for all Refurbishments and Renovations.

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