The Profi-mix system allows a suspended or batten floor to be heated from a very low heat source. Using 30-35mm of dry screed, the system will build up and hold heat. It also allows closer pipe spacing's if required to meet the heating demand of the rooms.
Install battens along joists to support 12mm OSB, which should leave a gap of 85mm to the tops of the joists. install 50mm rigid insulation.
Pipework is installed onto the insulation, following the CAD pipe layout diagram (provided). The pipes are then covered with a dry mix of sand and cement, to provide a thermal mass to hold and conduct the heat through the floor above.
Structural floorboards (eg Oak planking) can be installed directly to the joists. Otherwise, a structural floor deck (typically 18-22mm chipboard, or suitable screedboard, is installed onto the floor joists, with carpet or tiles above.
