Car Builders Mass Noise Liner Lite is a heavy weight sound barrier, with a total thickness of 8mm it will package under your carpet as a premium carpet underlay as used in high end luxury vehicles. The 4kg p/sm mass load vinyl upper layer is lined with a 6mm closed cell de-coupling layer to create the most effective means of acoustic blocking. Our flexible closed cell foam is water proof and offers superior thermal insulation.
Mass Noise Liner Lite is a "Stage 2" product designed to go on top of our Stage 1 Sound Dampening sheets. The lower foam layer works as a de-coupling layer to suspend the MLV (mass loaded vinyl) which is effectively a sound blanket. The approach using these 3 x materials (dampening, de-coupling and blocking) is the most you can do in the minimal space between your carpet and floor pan. This is the same approach used by NVH engineers when designing high end luxury vehicles.
This product is durable and non-stick, it does not require glue and will sit under its own weight. If desired, you can glue the MNL in position by applying contact adhesive to the foam side.
