Wundatherm Premium+ Board is made with 400 kPa polystyrene, the strongest available on the market.  Read our blog on why kPa is important! 200 microns will give optimum system performance, aluminium any thicker than 200 microns offers no performance gain and system performance will plateaux. 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, INSTARMAC and NORCROS approved for tiling onto - Using Mapei & Instarmac approved S2 flexible adhesive and primers please Refer to factsheet FO1b. *Natural stone may require a backerboard - please call for details or refer to Factsheet FO1b for specific details.

• 400 kPa - the strongest EPS board available (Uses 4 times the material of Wundatherm Low Density for superior strength)
• 16mm board uses 120mm pipe spacings with 60m pipe lengths
• 20mm board uses 150mm pipe spacings with 100m pipe length
• Mapei & Instarmac approved for tiling directly onto using specified methods as per Wunda factsheet FO1b
• 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 (available from Wunda) when using Ultra method just prime the aluminium first. If you wish to carpet or lay vinyl a suitable backer board will need to be laid on the Overfloor boards. 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.
