Luxury Liner Pro™ MLV + Foam Auto Sound Barrier Sheets

Luxury Liner Pro is the best automotive noise barrier out there. It has an STC 28. When paired with our sound deadening mats (Damplifier Pro) in a full vehicle install, they can reduce noise by 10+ dB in a loud vehicle (50%+ perceived noise reduction):

Luxury Liner Pro is mass loaded vinyl fused directly to a closed cell foam decoupler, so you install one sheet instead of two layers. The layers are fused together during manufacturing for a stronger, more permanent bond.

Yes, Luxury Liner Pro blocks both noise and heat. It has the mass required to block sound, and it has an R-value of 4.45 per inch, making it a solid insulator.

Luxury Liner Pro works on the cabin side of the firewall, the floor, the trunk or cargo area, and the doors. On a truck, cover the back wall. Aim for as close to 100% coverage as you can. A continuous barrier blocks road, engine, exhaust, and tire noise best.

Yes, installing Luxury Liner Pro on doors improves mid-bass when you use it to seal the door cavity. Sealing the cavity creates a sub-enclosure-like effect. Installing it along the inside of the door cavity with 100% coverage reduces road noise.

Yes, for the best results, use Luxury Liner Pro with Damplifier Pro. Apply Luxury Liner Pro on top of a constraint layer damper like Damplifier Pro or a liquid deadener like Spectrum. The damper controls panel vibration while Luxury Liner Pro blocks the airborne noise. In a full build, you can expect about 10+ dB of noise reduction in a loud vehicle (50%+ perceived noise reduction).

Each Luxury Liner Pro sheet is 24" x 54" (9 sq ft), and you're aiming for as close to 100% coverage as you can. You can measure your approximate square footage or use the vehicle square footage calculator above. You can also visit our vehicle square footage calculator page.

To install Luxury Liner Pro, map out how much you need and what cuts you'll need to make first. Make the necessary cuts with a utility knife (cardboard templates often help the process along). For flat surfaces, you can simply lay it on the metal foam-side down, as it is heavy enough to stay in place. For vertical surfaces, clean the bare metal with denatured alcohol, and use P329 spray adhesive on both the foam side and the substrate. Alternatively, you can use our super strong double-sided tape, or Dual Lock. Finally, seal the edges and seams with foil tape. See our Luxury Liner Pro install guide for the full steps.

The grey foam side of Luxury Liner Pro goes down first, against the application surface. The black MLV side faces up and out.

Dual Lock is the best choice if you may need to remove the Luxury Liner Pro sheet later. We recommend the 250-pin / 400-pin combo. On a horizontal surface, use 2' of Dual Lock per 9 sq ft sheet (1' per side). On a vertical surface, use 4' per sheet (2' per side).

There are two ways to install Luxury Liner Pro in a car door. Pick the method that matches your goal.

Cover the outer door skin

Use P329 spray adhesive to adhere Luxury Liner Pro to the outer door skin inside the cavity at 100% coverage. The grey foam faces the outer door skin and the black vinyl faces you. A cardboard cutting template helps.

Seal the door cavity

Sealing the open door cavity turns it into a speaker enclosure. Use Dual Lock to fasten it, since it is the most removable fastener. The grey foam faces into the cavity. A cardboard cutting template helps here too.

See our car door kit install guide for the steps.

If you need to fit Luxury Liner Pro in a tighter spot, shave down the foam side with a utility knife. You can also cut it cleanly with a Dremel tool and a small circular sanding bit.

Yes, you can bond carpet or other layers on top of Luxury Liner Pro with HH-66 Vinyl Contact Cement. Most adhesives struggle to bond to vinyl, but HH-66 gets the job done.

Luxury Liner Pro is 1/8" thick, 1 lb mass loaded vinyl (MLV) sheet fused to a 1/4" closed cell foam decoupler for a combined thickness of 3/8".
