Reasonably priced sound deadening
Size: 18 sqft
Easy to cut with a carpet knife. I used a heatgun to make it stickier and more moldable. The foil isn't so thick that you risk cutting yourself like some Dynamat variants.

Sticky so don’t let it touch you or each other but it comes off and works fine.

great for what im doing. maybe not as good in a vehicle though
Size: 36 sqft
decent product. not as thick as typical sound deadening but definitely cheaper. and for my application, i didnt need a name brand thicker material. i am putting it on our heat and ac vent and intake pipes during our remodel. sound travels from room to room in our old house through these vents and pipes so a little sound deadening goes a long way
