  • The material used is an excellent insulator! The sound deadener material allows you to deal with both, cold and the heat. This is especially important in hot climate areas. Well-insulated interior is a pledge of high comfort while in vehicle. Liner heat shield material will solve the problem of excessive heating if your car is equipped with a powerful engine and enhanced exhaust system. It is also easy to use Liner as the hood insulation (hoodliner).

  • Effective and Easy-to-Use Soundproofing Solution
Style: 15.7"x39.4" 4.3sqft
The SOOMJ 20mm thick self-adhesive soundproofing panels really deliver! Installation was super simple thanks to the strong adhesive backing. They noticeably reduce noise, making my space much quieter and more comfortable. The thickness adds great insulation without feeling bulky. Considering the price, this is a fantastic way to improve any room’s sound quality and comfort. ... show more

  • Very effective
Style: 15.7"x39.4" 4.3sqft
Super sound deadening material. I used this in my boat engine compartment to quiet the noise that he engine makes during operation. I went from steaming to my passengers to talking to them. I had to check to see if the engine was really running!

  • Very high quality!
Style: 15.7"x39.4" 4.3sqft
This is a very high quality product and a good value for the money. I used it to replace my 20-year-old rotting sound deadener mat on my boat's engine hatch. The new material is fairly thick, has a good backing layer and feels dense. I used 3M 90 contact spray adhesive to attach and it seems to have a solid, tight grip. Engine noise is now reduced. Would buy again. ... show more

  • Decent sound reduction
Style: 15.7"x39.4" 4.3sqft
I lined the engine space in my inboard boat. Noticeably quieter now. Adhesive did not stick to other foam, had to use some spray glue.

  • Works well when used correctly.
Style: 15.7"x39.4" 4.3sqft
I am an engineer and I used this material for noise insulation and soundproofing in the doors of my car when I installed an advanced audio system. I have used several types of materials for the correct acoustic design of car doors. I used this material one for the door cards. And under this material there is another layer for vibration insulation. ... show more

  • Fantastic Material
Style: 15.7"x39.4" 4.3sqft
Incredible material unlike anything I have ever seen or touched applied it to my Klipsch R28F speakers behind the tweeter and mid-range speakers just on the rear inner side of the speaker but not on the inner sides just the rear and omg what a difference in detail and resolution. the speakers have the same signature but detail and smoothness and clarity. This material feels and looks like NASA issue. Also applied it the rear of the tweeters as well. All that smuck is gone just clarity and depth. Panels were cut 8X16 I first cut a 16 by 16 then cut that in half. When you cut use a straight edge utility knife on the paper side. Press the knife though to the cutting board. make sure you use a new blade for a smooth clean cut. Start at the very top of the inside of the speaker and as you go pull the paper along. ... show more

Product adhesive let's go in hot temperatures and super cold temperatures. I had it in the trunk cutting out the droning noise it worked when it was in place but the adhesive did not last on metal
