Appropriate substrates include concrete, plywood or compressed fibre cement sheet (excluding particle board flooring) and optional floor overlays include fibre cement tile underlays or Warmup Insulation Backer Board.
The small diameter heating elements are available in a number of different lengths and wattages. View the sizing guide in our undertile brochure.
A range of programmable and non-programmable Warmup Thermostats are available.
Scope of use

The system must be installed on an appropriate structural substrate such as concrete, plywood or compressed fibre cement sheet (excluding particle board flooring) and must be protected from physical damage by a screed and ceramic or stone tiles.
Floor must be designed and constructed such that deflections do not exceed 1/360th of the span and movement and control joints in the substrate must be carried through to the screed, tile or stone finish.
