Wooden Subfloors
• Ensure adequate underfloor ventilation
• Existing floorboards need to be securely fixed and if necessary
pre-levelled with a latex/cement self-levelling compound to give a
flush fit for the subsequently applied WBP plywood (18mm) or an
Insulated tile backer board (Warmup® Insulation Boards).
• A rigid base is essential - Fixing WBP plywood or Warmup®
Insulation Board to joists will not provide a suitable floor finish for
accepting tiles.
• Refer to BS5385: Part 3: 1999, clause 14.4 for more information
on sealing the backs and edges of the WBP plywood before fixing.
• The above recommendations apply to floors of small areas as
advised in clause14.4 of BS 5385: Part 3: 1999.
Concrete Subfloors
• Ensure you use an extruded polystyrene building or tile backer
board (Warmup® Insulation Board) if installing your mat onto a
cement-based floor.
• Fixing the board should be as per the manufacturer’s
instructions.

The mat is available in 2 different wattages 150W/m2 and 200W/m2. Each mat
is designed to produce a specific amount of heat based on its length. For this
reason you must never shorten the mat.
