Design Engineering 050113 Under Carpet Lite 70" x 72" Sound Absorption and Insulation (35 sq. ft.)

How well does this mat actually block or absorb sound? I would use this inside my car, underneath the factory carpeting.

which side goes down for car floor pan installs?

need something for the floor of my 2018 jeep JKu to kill the heat, i dont care about the noise, what does the manufacturer suggest?

can this be used on house floors
