Sound Deadening Mat Automotive Thermal Deadener Deadening 50mil 12.5sqft w/Free Installation Roller

I use it in a window in my apt 1/8 inch plastic window the sound would travel right thru also west facing so dark is ok this stuff works good at sound deadening I still hear loud sounds but they seem farther away less immediate

I just put this in my 1967 Morris Minor Traveller and it made a difference in that it really cut down the exhaust noise and road noise. It was forgiving in installation which made it easy to install. I recommend this product.

My husband really likes this He put it in his 18 wheel truck to get less noise, but also to have some insulation to keep him warmer in his sleeper.

Light and does its job
