Application

  • Suitable for use on walls and floors (correct installation method must be followed - please check).
  • Suitable for wet rooms and replacing plasterboard in bathrooms.
  • Suitable choice for use when installing electric underfloor heating on to a concrete, screed or wooden subfloor.

Description

Fastwarm tile backer boards are built with high thermal performance. Made from high-density extruded polystyrene with reinforced coatings, they’re suitable for Fastwarm Sticky Mats, FastGrid, and Loose Cables.


The ultra-light weight backer board can be easily cut to size or to work around fixed appliances using a craft knife and are suitable for transporting on site due to their lightweight but strong structure.


Tile backer boards can be mechanically fixed to timber subfloors using screws and washers and / or fixed to solid subfloors using a flexible tile adhesive. The boards are moisture resistant and will reduce movement within the subfloor, making tiling on top of the system very simple.


Tile backer boards have been engineered to withstand compression values of up to 30 tonnes per m², whilst being extremely lightweight, highly efficient and competitively priced - making this durable thermal insulation a suitable choice for use when installing electric underfloor heating on to a concrete, screed or wooden subfloor.


Features and benefits:

  • Waterproof.
  • Approved by Instarmac (Ultra Tile adhesive manufacturer)
  • Super high insulation values per m².
  • Excellent sound insulation.
  • Cuts with a utility knife.
  • Thermal conductivity value of 0.027 W/mK.
  • Suitable choice for use as a thermal barrier with underfloor heating systems.
