Dynamat Dynaliner provides high acoustic absorption and excellent thermal insulation for a variety of vehicle applications. You can apply this self-adhesive Dynaliner sheet on top of Dynamat in several locations, such as your car's floor, doors, or roof. Dynaliner increases the efficiency of your vehicle's climate control system, improves stereo imaging by reducing high-frequency reflections, and reduces interior noise levels, especially in the low-frequency range.

Ultra-lightweight Dynaliner resists damage from oil and water, so you don't have to worry about accidental spills or splashes. Engineers constructed this ultra-lightweight insulator from crush- and tear-resistant material so it'll stand up in the challenging car environment. 1 sheet, 54" x 32" (12 square feet total ). Available in three thicknesses: 1/2", 1/4", and 1/8". Warranty: 60 days.

Features

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)

14 questions already asked

2019 Kia Soul---Will this negatively affect the sound from a downfiring sub placed on top of it, just inches above it in the spare tire well? I purchased this thinking it was the original/standard Dynamat. I have since ordered Dynamat EXTREME and will install that in my spare tire well.I CAN put this dynaliner over top, but SHOULD I? I have 500w RMS going to a slimline Kicker 12 in the Kicker sealed box. I'm just worried about the foam absorbing/deadening the sound.

santos Aug 19, 2022

1 answer

This Dynamat Dynaliner can only help the sound in this case, Santos! You can feel free to apply it in that location and proximity to the sub with no worry if you choose. This Dynaliner specifically catches high frequencies and absorbs sound and almost acts as insulation, and it's designed to go right over traditional Dynamat.This can help the overall sound of the sub by isolating the cabin even more than the standard Dynamat. The bass will move out in every direction, and the deadening won't change that much! I say if you have it on hand you SHOULD, but if you decide not you use it you can always return any products purchased from us within the first 60 days, risk free!

What is temperature resistance?

branden Jun 08, 2021

I would only use this for back side of door panels, too thin to do much more then that.

Can it be used to replace industrial felt used on the interior walls of a ported speaker cabinet?

dmc1966 Apr 21, 2024

1 answer

Hey Darryl, this can certainly be used on the inside of a speaker cabinet. If you have a speaker cabinet that is notorious for reflecting sound internally and we need to tighten that up a bit overall to improve sound quality and reflection, this will be great for that.

red Apr 22, 2024 (Staff)

how much better is the 1/2 than the 1/4 at thermal insullation?

robert v v Jul 18, 2022

1 answer

While there's not definitive number, from a thermal perspective, the increase is probably not going to be as exponential as the sound but there will be a difference.

arielle Jul 26, 2022 (Staff)

Are there any anti-static qualities of this material?

howard Jul 13, 2022

1 answer

Greetings Howard, and thank you for your question. The Dynaliner is made to insulate, increase HVAC efficiency, as a high frequency absorbing material. As far as anti static, all I can see is whatever static you may have, some will be absorbed by the material.

Thinking of using Dynaliner as a headliner in an old truck. Is it paintable?

jim Apr 08, 2020

1 answer

No sir, it's not. It's basically high density foam with a strong adhesive backing and it would be like painting an egg crate mattress. It does make a great underlayment under a headliner. Gives nice support and REALLY cuts down on road noise.

How much will I need to do my 68 Chevelle doors trunk and floor ?

tom Feb 27, 2024

1 answer

Greetings Tom. Crutchfield is not going to measure a vehicles square footage. Unfortunately, you are going to have to measure that yourself. Dynamat has a calculator application on their website. Not vehicle specific, just coupe, sedan, truck, van etc. That might give you some assistance. of course, they are doing it based on a more modern-day vehicle. Personally, I would add more square footage to their calculator. Nice ride by the way. https://www.dynamat.com/calculator-new/

what about Marine use - on a engine room bulkhead? mechanically fastened

Should work for noise . I used it for the floor on a truck

bill Dec 07, 2020

I'm not a boat owner, but I don't think the product is designed to be used in a continually wet or very high heat environment. If it's dry, my concern would be fire hazard. I think you should contact Dynamat directly.

robert Dec 07, 2020

Can this be the only layer you use or should it be 2nd layer on top of DynaMat?

mitcho Apr 27, 2016

1 answer

You can use both but you shouldn't have to. If the primary issue is vibrating surfaces (at specific frequencies; usually when the bass hits), go with the Dynamat. If you need to reduce exterior noise (road, wind, etc.) then go with the Dynaliner. Either product can work for either issue, but they are optimized for the applications I've described. I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5

Which is best for trunk noise, most road noise comes from the trunk! This or the dynamat with the silver looking side? I am getting this for my sons 2012 Mazda 3. Also, how many should I buy?

dana Dec 15, 2013

4 answers

that's a pretty cool father/ son bonding exercise! Anyways, they should have dynamat kits for trunks - i think it's called Extreme. You'll probably want to take out the side carpeting in his trunk and do that too. But likely it's like the dumb stuff like a license plate/ frame that rattles too. I typically put silicone bumpers on the back of those.

eric t. Dec 28, 2013

I would start with dynamat, you can always add dynaliner over it if your looking for extra quiet or have a ton of bass as for quanity bulk packs are generally a better buy, plus any extra can be used in doors, floor boards etc

eugene Dec 16, 2013

If you are just worried about road noise this will work. The dynamat (silver lined) is used in applications where aftermarket bass is being used since it neutralizes rattling from panels. The amount you need is dependent on the size of the trunk.

Dynamat First, then on top Dynaliner. Square Footage

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
