Acoustic insulation without demolition of an existing floor slab with new ceramic floors using an under-tile insulating layer: solution with FONOSTOPTile Biadhesive (max. tile size 30x30 cm)

FONOSTOPTile is an innovative and versatile product; it is an under-floor insulation material consisting of a non-woven polyester fibre fabric with high resistance and sound-resilience, coated on both sides with a waterproof elastomeric layer, for the acoustic insulation of impact sounds and the waterproofing of internal floor slabs, for the protection of the flooring from the movements of the laying surface and from dampness.
FONOSTOPTile Biadhesive: this version has two self adhesive faces protected with two removable silicone films and is bonded in complete self-adhesion at room temperature on a cementitious substrate (which must of course be level and be adequately clean) or even on existing flooring, on which it will subsequently be possible to lay ceramic, stoneware or wood flooring or resilient flooring in PVC, rubber or other material, by direct self-adhesion without having to apply adhesives and subsequently only having to do the grouting joints of tiles (for floors that require it).
