Luxury Liner™ Sheet - Mass Loaded Vinyl (1 lb / 2 lb)

Luxury Liner 1 lb sheet has an STC rating of 26. Luxury Liner 2 lb sheet has an STC rating of 32. Here is how each one performs across the frequency range:

For most automotive projects, choose 1 lb. It is thinner (1/8") and more flexible, so it wraps around curved interiors. Choose 2 lb for flat surfaces or where you need extra sound blocking. It suits small, high-blocking jobs like soundproof boxes. You can use 2 lb in a vehicle, but only where it lies flat, because it is much less flexible.

Sheets of Luxury Liner mass loaded vinyl go on the vehicle floor, including under the rear seats. They also go in the trunk (floor, quarter panels, and wheel wells) and on the cabin side of the firewall. Use them anywhere road, engine, exhaust, or tire noise needs to be blocked from entering the cabin. Mass loaded vinyl needs 100% coverage to work as a barrier. Leave enough clearance to reinstall carpet, seats, and trim. Don't cover drain holes or mechanical devices, and never install it next to a heat source. We recommend pairing it with a closed cell foam decoupler like OverKill or OverKill Pro.

For the best results, install sheets of Luxury Liner mass loaded vinyl on top of a constraint layer damper like Damplifier or Damplifier Pro. Pair them with OverKill or OverKill Pro closed cell foam underneath. The foam decouples the MLV barrier from bare metal or hard plastic.

Each sheet is 24" x 54" (9 sq ft), and Luxury Liner mass loaded vinyl needs 100% coverage to work as a barrier.

Luxury Liner Sheet is plain mass loaded vinyl. You can add your own foam decoupler underneath. Luxury Liner Pro has the foam fused to the MLV in one 3/8" sheet, with built-in decoupling and heat insulation. Choose plain MLV sheets when you want to pick your density (1 lb or 2 lb) or if you want to install closed cell foam separately. You should also choose plain MLV sheets when you don't have space for foam or simply don't want any.

Sheets of Luxury Liner mass loaded vinyl are pre-cut from the Luxury Liner rolls to handle smaller jobs. The rolls are made for larger jobs like soundproofing walls, fences, and ducts.

To install sheets of Luxury Liner mass loaded vinyl, cut each sheet to size, install a closed cell foam decoupler, and then lay the MLV on top. You can use HH-66 to adhere the MLV to the decoupler. Seal the seams with foil insulation tape. For best results, install Damplifier Pro or Spectrum to the bare metal to reduce the structural noise. Then lay down your decoupler and MLV.

Cut Luxury Liner Sheet with a sharp utility knife. Leave enough clearance to reinstall carpet and trim. Don't cover wires, drain holes, or mechanical devices.
