Very good stuff really really helped 2001 f250 7.3 made it much much quieter then before! Very impressive! Ac works great now ice cold

Amazing sound deadening great insolation to

Nice product came quickly.A little pricey, but easy to apply.Is it cut gave it 4 stars?Because I do not have my car back together.To find out how much sound that need it provided.

This stuff is pretty easy to apply... just make sure to place it where you want it the first time. My jeep is black so it absorbs the heat and it took a while to cool it down with the ac. This stuff helped so much. It cools down faster and doesn't get as hot. Big difference. It works for noise reduction as well. Great purchase here. I used simple green to clean the surface. A lite amount and rinsed with a clean wet cloth. Holding up under the summer heat.

Good product, but move slowly on install. When it sticks you cannot reposition.

Most sound deadening products cost a small fortune. I own a Jeep Patriot. With this single box I was able to insulate back up to the front seats and the ceiling with enough leftover to do the doors. This doesn’t deaden sound as much as maybe more expensive products would but I know it insulates a little bit and it reduces vibrations. So it makes music sound much better. I give this product 5 stars due to cost effectiveness. It’s easy to use and you get a lot for what you pay for. If it was twice or triple the price it would get a lower rating.

Great product

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

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.
