Siless Liner 157 mil 51 sqft Aluminum Foil Finish Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener

Great product, easy to cut with scissors and install. Very sticky so make sure where you place it, you want to keep it. Well made and has seem to cut down on the transfer of heat I. My vehicle roof. Size is more than enough, well worth the money.

Good product customer service with Siless when I had questions was very good too.Take your time with this product it is very sticky once it touches the surface there is no turning back.Have the right tools and once you make a cut dry fit to make sure it fits.My work van is quieter now and cooler

Work perfect easy for installation

Nice product. With adhesive applied, this an all in one product. Easily cut to random shapes and dimensions and the adhesive seems to hold well. Removing the paper that protects the adhesive to apply in tight areas, presents a new set of problems. Having applied the product inside the panels of an old Trooper, it is yet to be determine if sound and temperature transfer are reduced.

great material I used under the doghouse in my class A rv. Reduces the noise and heat from the engine area.

I just used this too insulate the fire wall area in my RV. Cuts easily with scissors. Sticks very well to most surfaces.

We used it on the inside of a jeep hard top. So far no complaints. The glue sticks. We were worried about the 110° temps and so far so good

Great for insulating our van

This product does not perform. It shrunk by around 25pct after exposure to heat and sunlight covering the cars Panoramic Roof.

Very sticky so be sure to dry fit the panels before to take the vinyl strip off , because as soon as you touch it to the metal there is no adjusting it, however it really does what I wanted it to , to reduce sound , vibration and heat inside the truck cab

Excellent adhesion, impressive results on my 2019 Tacoma. Very fair reasonable price. Highly recommend.

They have nice square markings on back side for easy cutting measurements , and the bonding to surfaces in very good , even to primed surfaces . And removal of backing is effortless and peals off easy and clean . Seems like a very good product . Works excellent as well for making new seals for removable floor panels in semi floors .

I'm not sure what the foil adds except a layer on top to rip. These used to be simple closed-cell foam but I have no idea why they are including a micron-thick layer of foil to the top - for what reason??? These are not forgiving to work with. Once you lay it down, it sticks, and will rip if you try to reposition. This makes them very hard to work with in tight spaces or when trying to slide under something.
