Dynaliner performance

Written By MrWill, Madison, VA on Monday, July 27, 2015

Liked the closed cell structure of the material, like a combination of rubber and vinyl to really help absorb and block incoming noise. I used this product in conjunction with several different strategies and products to lessen the noise inside my '97 Pickup, which had no insulation on the back cab wall, with a much improved reduction in noise. I used carpet padding as well and feel that I Could get similar enough results with it for 10% of the cost. I'm not a "brand guy".

Pros: Good rubber-vinylish combo material, shouldn't mind getting damp. Lightweight, probably less than 2.5lbs

Cons: Expensive for only a 54" x 32" piece of material.

Crutchfield Customer Review (What's this?)

Used Dynaliner in rear of cab in 99 dodge ram extend cab. Installation was a breeze. I did have to cut it an installed in two halves because original dimension didn't cover the area I needed to cover. But by cutting in half and turning it 90 degrees I was able to cover the area with no problem.

Pros: Easy to work with. Material is to cut/trim if it needs to be. Attaches to surface being applied on.

Cons: No problems or complaints with Dynaliner

The Dynamat Dynaliner worked well in our show displays. It also worked well for cushioning some sensitive components.

Cons: A little pricey.

Crutchfield Customer Review (What's this?)

Bought carbon fiber hood and wanted to avoid cutting parts of it to make stock heat shield fit. After shopping around decided to give this a try. Was a bit difficult putting down by myself but eventually got it and not only does it look great it works amazing. After two hour drive in 90 degree weather hood was cool to the touch. A must use product when dealing with aftermarket hoods.

Pros: Flexible and adheres great once laid down

Cons: Difficult to get even set when trying to fit around things like air dam for TMIC.

Easy to use

Most people will be familiar with this product. Replaced the complete lining on the rear cab of my truck. Easy to install and conforms well to contours.

Crutchfield Customer Review (What's this?)

My wife and I installed Dynamat and Dynaliner on our 1952 Chevy Pickup daily driver.
Primarily to keep warmer during winter months. Installed on roof above headliner and
behind seat and in doors and on floor. It seems to help the sound system too. There are
other brands, but have used this before and know I can depend upon good results. And the
service from Crutchfield is excellent too. A company we have depended upon before.

Dynamat Dynaliner

Crutchfield Customer Review (What's this?)

Product performed just like I expected. I covered the doors in my 72 Camaro, before installing rebuilt door panels, and modified speaker enclosures.
Used my heat gun to make it conform better to door frame, don't get it too hot, but that should be a no brainer!
Haven't finished with stereo install yet, so I can't tell you how much sound it blocks, but I expect it to be a major improvement over old 72 Camaro rattles.
Wish it was a little less expensive, I'd do the whole car!!!

Hands-on research

What's in the box?

  • One 1/4"-thick sheet of Dynaliner

Product Research


Overview: Dynaliner is an ultra-lightweight, closed cell, high performance insulation. It provides acoustic absorption and thermal insulation for a variety of vehicle applications. The dark gray Dynaliner has a self-adhesive backing, with a high-temperature acrylic adhesive, for easy application. This durable, crush and tear-resistant material is not affected by oil and does not absorb water. Dynaliner meets both UL (Underwriters Laboratory) and FMVSS (Federal Motor Vehicle Safety Standards) flame resistance.

Typical Uses: Dynaliner is used on top of Dynamat in the doors, on the floor (under the carpet), behind the headliner, on the interior firewall, or under the hood. The Dynaliner/Dynamat combo can be used in place of carpet pad. Benefits include noise reduction, improved air conditioner/heater efficiency, and improved imaging (reduced high-frequency reflections).

Installation: Using a razor knife or scissors you can cut Dynaliner to the desired size and shape. Dynaliner is self-adhesive, and should be mounted on a clean surface, free from dust, grease, debris, or moisture. For best results, work evenly from one side to the other, applying even pressure.

Temperature Range: -30° to +200°F (-34°C to 94°C)
