## Description

Second Skin OverKill Pro is a 3/8 inch thick closed cell foam that should primarily be used as a decoupler to prevent rattling by plastic panels, mass loaded vinyl, speakers, and other metal parts of the vehicle. Overkill Pro also reduces music distortions caused by sound waves bouncing around the vehicle’s cabin, helping to improve the audio system acoustics in much the same way that a carpet reduces echos in an empty room. As a closed cell foam, OverKill Pro will absorb some low frequency sound waves, targeting road noise, engine noise, and exhaust noise. Polyethylene foam has been d for safety and will not off-gas chemicals, making it safe for use inside vehicles.Pro Tips:Use OverKill Pro as a decoupler under a mass loaded vinyl product (ours is called Luxury Liner) on the floor, firewall, and trunk to create an extremely effective noise barrier.Some of our professional installers swear by stuffing OverKill Pro into any gap where plastic panels can rattle (even cupholders!), shaving a couple of decibels just by ensuring all your paneling is cushioned.We recommend applying closed cell foam with a high temperature spray adhesive or super strong double sided tape. Second Skin offers options for both.Always apply OverKill Pro to the interior of the car cabin. Polytheylene foam should not be used next to a heat source.

## Features

- CLOSED CELL FOAM SHEET: Second Skin OverKill Pro is a 3/8 inch thick closed cell foam sheet that works with sound deadening and barrier products to reduce vehicle noise. Each sheet is 9 Sq Ft (2 ft by 4.5 ft).
- DECOUPLER: Closed cell polyethylene foam will not block or absorb large amounts of sound, but it does an excellent job of decoupling two hard surfaces. Create a cushion to stop rattles and vibration noise caused by speakers, subwoofers, plastic panels, an
- HIGH DENSITY INSULATION: Highly water resistant, heat resistant up to 165 F, and an r-value per inch of 4.33. OverKill Pro is one of the toughest closed cell foam insulation sheets on the market.
- IMPROVE SPEAKER ACOUSTICS: Reduce sound distortions in your car’s door panel by installing a closed cell foam “carpet” to reduce the empty room effect inside your door.
