MARMOX BOARD PRO / ULTRA TILE BACKER BOARDS 29 MARMOX BOARD TILE BACKER BOARDS 9. MARMOX Board PRO - Insulation under electric underfloor heating system MARMOX Board PRO is designed for application under electric underfloor heating systems. The boards are heat insulating, compressive resistant, and ready for tiling. The boards are available in a wide range of different thicknesses from 6 mm - 100 mm, which affect the reaction time and the energy consumption accordingly. Electric underfloor heating is particularly popular in kitchens and bathrooms. Heating cables are mainly embedded in self-levelling compounds or flexible tile adhesive, directly installed on concrete floors. In cases where no insulation under the heating wires is installed, the energy loss can reach 40% of the total energy consumption for the heating of the basement and not for the tiles. That effect is a considerable disadvantage for the comfort and effectiveness of electric underfloor heating systems. The installation of MARMOX Board PRO for insulation under the electric underfloor heating system, either on concrete, screed or wood construction provides two main advantages: reduced reaction time to heat up the surface temperature reduction of energy consumption MARMOX Board PRO is recommended by well-known producers of electric underfloor heating systems thanks to the excellent product properties. tiles tile adhesive heating wire concrete floor tiles tile adhesive heating wire MARMOX Board PRO tile adhesive concrete floor
