)
Multiboard can be used to insulate and waterproof walls, floors and ceilings and noticeable benefits will be gained by using any thicknesses of 10mm and above. The thinner 4mm and 6mm boards are mainly designed as waterproof tile backer board options, but these will also provide some thermal insulation. Even the thinnest boards will be useful when used with underfloor heating wire to reduce your heating costs.
