Customers like the noise reduction of the insulation.

Awesome stuff! The only thing I would have done differently is just buy the 120 mil right away. I just did 2 to 3 layers o the 50 mil depending on the area. Improved the sound quality of my stereo system and got rid of the door rattling from my sub and door speakers. Highly recommend

This stuff is extremely easy to install and it sticks to everything! So far I haven't had the truck able to drive yet but just tapping/banging on various areas it has completely rid the cab of the "tin can" sound. Great product hopefully its worth it once I go for the first drive.

Viene muy bien embalado, y en excelentes condiciones, también que rinde muy bien, con una caja logre puertas y cajuela, y sobró material, el rodillo no es indispensable para la instalación ya que no entra en las depresiones que tienen las láminas, sin embargo si lo añadieran en el paquete sería Perfecto!!!

Used in my 1997 C1500 pickup when swapping from vinyl floor to carpet. Made a huge noise reduction difference in the cab (Turbo V8 truck with 4" exhaust). Have quite a bit left over too (Single cab truck).

Very easy to install. I ordered the 3 roller tools separately for install but I found they weren't needed. This mat presses down easily with your hands into any valley or raised area. Very easy to cut with a utility knife.

Adhesion is excellent. I have no worries about it loosing adhesion or sliding around under my carpet. And when installing, I had to pull a couple pieces up after to move and it released nicely off the metal floor without destroying the piece of sound deadening and was able to reuse without issue.

Would definitely buy this again. Great product and significantly less expensive then the brand name stuff.

I bought this to use on my van which I'm converting to a camper. To be honest I didn't know what to expect as I have never been in a car/van with sound deadening. I can honestly say that after fitting it there is a marked difference (even my good lady noticed it. It is not the cheapest on the market but definitely not the dearest but it works. I found it really easy to use, the adhesive is very strong and its really easy to cut to shape too. If I need any more I wouldn't hesitate to get it again and I would definitely recommend it.

Viene en una caja y nada de maltratado, compre la caja de 4,7 metros cuadrados, la instale en las 4 puertas de un carro sedan y aun tengo material quizá para insonorizar la cajuela, pega muy bien al metal una vez que se retira el polvo o la grasa, si recomiendo utilizar un rodillo para su instalación ya que facilita que todo la hoja quede bien pegada

Reviewed in Canada on August 11, 2021
Used this material inside my 2021 Kia Seltos in an attempt to lower the cabin noise. Applied it to the wheel arches, trunk floor, and inside the rear hatch. The product goes on easy and with the proper application using rollers, you can achieve a near professional outcome with modest effort. Cuts easily and can form around modest curves and undulations in the surface. Force it too much and the foil will tear and leave the butyl underside exposed. That stuff is sticky and will transfer to anything that touches it so best to cover any tears with another piece.

In the end, it did lower the road noise in my Kia. As much as I hoped? No, but I am still glad I used this product. It's affordable and effective.
