MEDIPHON® is a laminated acoustic and safety glass. it consists of two or more sheets of glass assembled using one or more acoustic BPV films(Butyral of acoustic Poly Vinyl).
It has supperior performance compared to MEDLIAM® glazing of equivalent composition.
Thanks to its specifically adapted BPV, the accoustic MEDIPHON® achieves optimum acoustic performance in both single and double glazing, thereby providing comfort and well-being for the occupants.
Sound insulation:
MEDIPHON® presents acoustic insulation performances that are superior to those of a MEDILAM glazing, with an equivalent composition, assembled with a standard PVB.
Mechanical resistance and safety:MEDIPHON® has a mechanical resistance and safety performance level that is identical to that of a standard MEDILAM glazing with an equivalent composition. In the case of breakage, the glass fragments remain adhered to the BPV interlayer, thus reducing the risk of injury.
