16mm boards require 12mm pipe in 80m (inc. up to 20m transitional) lengths using 120mm pipe spacings 20mm boards require 16mm pipe in 100m lengths using 150mm pipe spacings Approved for Tiling directly onto - without the need for a backerboard*, just prime the aluminium for tile adhesives.
Wundatherm Ultimate 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 approved for tiling directly 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.
