Siless Liner 157 mil (4 mm) 51 sqft Car Sound Deadening Closed Cell Foam & Heat Insulation mat - PE Foam Sound Deadener Material & Heat Barrier

Si buscas reducir la resonancia de la lamina debes usar primero caucho butilo y despues agregarle esta espuma encima para mejores resultados. Cumple perfectamente con su funcion que es aislar y sellar paneles, al sellar puertas mejora la acustica de los altavoces, evita vibraciones y ruidos si se usa como empaque o junta al montarlos, el adhesivo es muy fuerte, se pega excelente y es dificil removerlo, no desprende olor alguno aun con el coche cerrado todo el dia bajo el sol a 38 grados.

Easy to install. I installed it on top of kilmat on the ceiling of my gmc savanna. The day after I put it on I slept in the van. When I awoke I asked my daughter if it rained last night. She said it was intense rain and wind. I never heard a thing, slept through the whole storm. The combination of these two sound deadening together can’t be beat. Totally recommend.

This is a good product at a good price. I used it to sound deaden my car and it has been working well along with butyl mat and a rubber overlay. I would purchase this again if need be, unless they increase the price. I got it for $100 for the box, any more than that and you should look elsewhere.

Used under the spare tire in Dodge caliber with an aftermarket muffler. This helped with the low drone at stop lights at idle and less noise on the highway. I used three layers.

So, I'm using this in my jeep as the secondary layer on top of the butyl layer. I can definitely tell this will work. Adds mass and the thump test is audibly different. My issue is with sticking. I'm cleaning the metal with dawn and it's very clean. It sticks really well to your hand, but it's hit or miss on the actual sheet metal. I'm using a roller and areas are still unsticking. I recommend buying an adhesive spray to use with this to get the best results. If I did this again, I'd spend more money and buy the soundskins deadener. Premade combination of both materials.
