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

The peel-n-stick is super nice. It's sticky and doesn't let off your fingers easily so be ready to stick it and leave it - there's no redo. I am a little disappointed that there's lifting after-the-fact. But that's a very small point as 99% of this product is amazing! The ride is quieter and I'm happy with the overall everything of this product.

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.

Works well

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.
