Dampens noise and vibration but does not stick well

Anonymous from Powell, OH on 9/25/2017

Crutchfield Customer Review (What's this?)

Great packaging and feels like a quality product. Seems to help with noise but does not stick very well. I cleaned area with alcohol first and rolled it down and its still coming up. I used it in my rear wall in my truck.

Pros: Dampens noise with no issues. Feels nice.

Cons: Adhesive does not stick well, even with proper prep and application.

Crutchfield Customer Review (What's this?)

My go to product when I need heat or noise insulation. Used this order to insulate a rear mounted auto air conditioner from heat in the trunk of the car. Dropped the temperature of the cooling air by about ten degrees (55 to 45 or 46 degrees) on a 90 degree day. Makes the unit much more efficient.

Dynaliner 1/8"

Hardcore Harley from Arkansas on 10/1/2016

I used the 1/8" thick Dynaliner in two areas of my 2016 Ford Transit Connect Cargo Van. I used it on the front driver and passenger doors over Dynamat Extreme. That's as much as I could get by with behind the door panel trim. That alone provides some degree of thermal barrier on the door panel as well as additional sound dampening. The second location I used it on is a metal bulkhead. The bulkhead had a vibration rattle at certain rpm's and poor road conditions. So I started with Dynamat Extreme on the backside of the bulkhead (the side in the cargo area) surrounding the perforated window in the center of the bulkhead. Then I applied 1/8" Dynaliner over the Dynamat. That totally eradicated the rattle. I have no regrets going the extra mile in expense and installation time by using Dynaliner throughout my Transit Connect. I used 1/2" Dynaliner on the roof, the two side slider & two rear doors and several body cavities. I used 1/4" Dynaliner on the window metal panels (where the glass windows normally would be). I used the 3/4" Hoodliner over Dynamat Extreme inside the engine hood. I would estimate the engine--which was already quiet from the factory--was about 20% quieter at idle speed. You'll benefit having both a thermal barrier and additional sound dampening using Dynaliner over Dynamat Extreme. Yes, it is worth it! Beware: purchase only from an authorized Dynamat vendor. Dynamat voids their warranty if purchased from an unauthorized d

Pros: Super easy to install. Further enhances sound deadening over using just Dynamat alone. Reduces thermal transfer of heat. Dynamat, Dynaliner and Hoodliner is the single best investment I've ever made on a new vehicle.


This Stuff Works!

Hardcore Harley from Arkansas on 9/5/2016

Crutchfield Customer Review (What's this?)

I just took possession of my new 2016 Ford Transit Connect Cargo Van that I use for film production. I immediately installed Dynamat Extreme and Dynaliner throughout the entire interior. I created templates for every single cut in advance. The templates helped to dramatically speed up the installation process and reduce waste to virtually nil. Because the van is all black, I also opted to use 1/2" Dynaliner on the roof to reduce thermal heat transfer. I used 1/4" Dynaliner on all the metal body panels and body cavities (over Dynamat) and used 1/8" Dynaliner (over Dynamat) on the front driver and passenger doors behind the door panels. While I primarily used the Dynaliner to make the interior a little bit cooler during the summer months, I was impressed at how much it assisted in aiding additional sound deadening, a noticeable difference over just Dynamat alone. I also installed Dynamat and 1/8" Dynaliner on the back side of the metal bulkhead to stop an annoying vibration noise. I taped every seam and edge with Dyna Tape to prevent butyl seepage on my film gear and cases. I can't believe how much difference the Dynaliner made on all all black van in summertime. I would estimate it is 5 to 10 degrees cooler inside on hot days. Bargain hunters beware: Dynamat only warranties their products when purchased through authorized dealers. They don't sell their products on Amazon. Don't get taken by knock off products on the gray market.

Pros: Super easy to install. Further enhances sound deadening over using just Dynamat alone. Reduces thermal transfer of heat.


Dynaliner performance

MrWill from Madison, VA on 7/27/2015

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.

Whitten from Mountain Rest SC on 2/13/2015

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

Lots of work to apply but worth it.

Pros: Insulation, sound deadening, apply everywhere

Cons: Lil pricey

Great product

Derek from Ny on 6/22/2013

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.



Dynamat Dynaliner

Glenn from Portland, Oregon on 9/7/2010

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

Erik from Visalia,Ca. on 3/15/2009

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!!!

3 questions already asked

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: [ Ryan  Apr 29, 2016 ]  Staff
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.[ DEREK  Dec 16, 2013 ]
Dynamat First, then on top Dynaliner. Square Footage[ RICK  Dec 16, 2013 ]
