Mass loaded vinyl, also named as MLV and rubber sound insulation felt underlay, is made from EPDM rubber. As it’s known to all, sound insulation material must be mass material. 3mm thick sound proofing membrane has a density of 4.0 kg/m2. That is quite heavy. Unlike other soundproof material, mass loaded vinyl is flexible. This MLV soundproofing is environmentally friendly and human friendly, too.
The acoustic isolation decibel is up to 26dB – As effective as 10mm cork! Excellent for under tile applications where grout cracking is a concern.

Urethane as Binder
Mass loaded vinyl acoustic block can be widely used in residential homes and public places such as disco ballrooms, gymnasiums, factory workshops, home cinemas, hotel lobby, hospital, shopping mall, school, piano room, conference room, studio, recording room, KTV rooms, bars, industrial plants, room, etc. The mass loaded vinyl epdm sound proofing can hugely reduce noise coming from vibration.
If the original floor can be more than 15cm thick and the sand & cement layer over the vibrating-absorption sound isolation rubber can be more than 4cm thick, airborne sound insulation can reach 55dB; crash sound insulation can reach 46dB.
