Due to recent hot & humid weather conditions, the aluminium covering may become discoloured. This is purely cosmetic and will in no way affect the performance or longevity of the board. 16mm boards require 12mm pipe in 60m lengths using 120mm pipe spacings 20mm boards require 16mm pipe in 100m lengths using 150mm pipe spacings Suitable for Laminate, Wood, Carpet & Vinyl when using intermediate backer boards.
Wunda's low profile Budget Boards are 100kPa compressive strength boards with a 50 micron thick aluminium coating. Ideal for well insulated homes where Rapid Response® isn't required. Wunda's Budget Boards are lightweight, easy to fit and designed to be fitted over any existing or new floor. No specialist tools are required, just an intermediate backerboard. The overfloor boards can be simply cut to shape using a fine toothed saw or craft knife. Quick to install using Wunda Spray contact adhesive ready for use straight away.  
      • 100kPa strength - ideal for budget conscious projects
      • 50 microns aluminium for even heat across the entire floor
      • Easy to cut to shape with basic tools
      • Eliminates the moisture, weight, mess and lengthy drying times of a screed Underfloor system
      • Similar spec as competitors overfloor, overlay and floating floor panels
  Remove product imageLaminate and engineered wood can be laid when using an intermediate backer board. 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.

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. 50 Microns is a thin foil covering giving slower performance and is only suitable for New Builds with good insulation where rapid response is not required.

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