Soundproofing Fonas 2.8 20m2/package ISOVER

ISOVER Fonas 2.8 is an ultra-thin, high-performance sound insulation membrane, specially designed for effective protection against impact noise in inter-storey floor structures. It consists of a high-density glass mineral wool felt, which is factory-impregnated with a special bitumen mixture and backed with a polypropylene veil (fabric). The product is the ideal engineering solution for laying under floating reinforced screeds, when the structural height of the room is limited and does not allow the use of thick thermal insulation boards.

Thanks to its unique multi-layer structure, the membrane provides excellent impact noise attenuation (up to 24 dB), permanently interrupting sound bridges caused by footsteps or furniture movement. The material is extremely elastic, chemically neutral, odorless and resistant to rot, aging and mold. It is supplied by SAINT-GOBAINE BULGARIA EOOD in the form of easy-to-handle and unfold rolls (packages) with an area of 20 sq.m.
