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.

We are converting a mini van to a weekend camper & used these as 2 layers on the floor for insulation & noise reduction after removing the seats. They stick REALLY well and, since we got the larger order in squares instead of a roll, the pieces were very easy to work with. The biggest trick is to start the peel back, place the square with just an inch or so of sticky exposed then peel as you smooth. Keeps out air bubbles and allows for a minimum of "straightening" if needed. We have enough squares in the box of 51 to do 3 full layers, 2 below the wood flooring and one on top of it when it goes in. It is squishy enough to make for a really nice padding layer under the final flooring (low pile carpet) that we put down.

I used this on my 2006 GTO after I mini-tubbed it. This material went in VERY easy and the sticky backing adhered to the car very well. I would suggest cleaning the surfaces with a damp towel for the best adhesion, to remove any surface dirt or grime. I used this stuff in the rear 1/4's, over the wheel wells and on the floors and factory seat backing (metal). Some of these places didn't have any sound deadner from the factory. I also reinstalled the factory sound material over this product. Because this product is very thin, it didn't interfere with the OEM stuff. It fits pretty muck every where in the car. PLUS, it's fairly easy to cut, using a good set of shears or scissors.

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.
