Mafi wooden floors are a secure option over underfloor heating. The three-layer construction of a Mafi board ensures a balanced floor that will not warp or cup. The top and bottom layers are the same species for identical expansion and contraction, with additional stress neutralized by the middle layer.
Without coating, there is no risk of chemicals vaporizing into the room as the floor is heated, which maintains a non-toxic environment. Mafi floors are glued directly onto the heated slab to minimize thermal resistance and maximize heat transfer. mafi.com.au
