High Heat Output - Provides room heating to properties that typically have high heat loss or limited insulation
The ThermRite under tile sticky mat heating system is suitable for a wide range of floor coverings – ceramic, stone, limestone, slate, terracotta, porcelain or marble. The system is designed for installation directly below tiles and stone flooring, and the following instructions should be read carefully before you begin your installation. The system can be applied to insulation construction boards, concrete, and existing old tile surfaces making it extremely easy to install.
Approved to EN60335-2-96 as required by the 17th Edition Wiring Regulations (BS7671:2008)
- Quick installation - Simply roll out the electric underfloor heating mat & fix to the floor
- Suitable for tile, stone, slate and marble floor finishes
- Continuous metallic earth screen to ensure electrical safety
- Low build height - Minimal floor height build up
- Suitable for use in wet areas
- EMC Safe
- LIFETIME WARRANTY
IF YOUR REQUIREMENT IS OVER 12SQM PLEASE PURCHASE EXTRA KITS TO MAKE UP THE AREA BUT SELECT NO THERMOSTAT OPTION FOR ADDITIONAL KITS - THE MULTIPLE MATS CAN THEN BE CONNECTED TOGETHER MAKING ONE LARGE ZONE
Wooden Subfloors – timber floorboards and chipboard. Make sure any loose boards are firmly fixed and reinforce the floor if necessary. This will prevent any movement in the floor that could cause tiles to crack. The floor must be level.
A rigid base floor is essential. Fixing reinforcements direct to joists will not provide a suitable floor finish for tiles. Reinforcement can be applied to the rigid base floor by covering the complete floor with 18mm WBP plywood (weather & boil proof plywood), or alternatively 10mm thick insulated tile backer board (construction board).
Reinforcements to be applied in accordance with the manufacturer’s instructions.
Concrete Subfloors – Before proceeding repair any imperfections in the floor and level the floor with approved building materials.
When practical, use XPS or tile backer insulation boards if installing the mat directly onto a concrete floor.
Wooden & Concrete Subfloors - Clean the floor surface so that it is free from dust, dirt, grease etc.
When it is practical, tile backer insulation construction board can be applied overall to both wooden and concrete sub floors.
Prime subfloors with a suitable primer to improve bonding between tile adhesives and the subfloor. A primer with a flexible admix is recommended. This is used to prepare and stabilise porous and dusting surfaces prior to tiling and to improve adhesion on difficult substrates, such as timber, concrete and terrazzo.
When installing insulation construction boards use tile adhesive to fix the boards to concrete floors and galvanised screws/washers on wooden subfloors. NOTE: Insulation construction board is already primed, comprising a cement polymer mortar finish on both sides of the board.
