Quality Materials Matter for Sound Deadening. Don't Be Fooled.
The best products combine a butyl rubber, elastomeric material with a thick, high-quality foil. That's what we use to manufacture our Damplifier™ and Damplifier Pro™ peel-and-stick sheets. As we mentioned earlier, the quality and the thickness of the rubber and the foil determine the material's overall effectiveness. You can see the thickness of the rubber and the foil on most technical specs – if they're hiding it from you, you may want to avoid that product.
The worst quality sound deadening material you can buy is made from asphalt roofing material. (We don't sell that.) Yes, asphalt will deaden metal. And while it doesn't perform as well, there are always customers who are willing to sacrifice performance to save some money. The only time we'd absolutely say no to asphalt is if you live in a warmer climate, because asphalt will melt and out gas chemicals at temperatures as low as 120°F. We'd rather avoid the sticky mess and the fumes, so we keep the asphalt where it belongs – outside the car.
How do I know if a sound deadener has asphalt? None of them mention asphalt anywhere! (Wonder why that is…) It can be hard, but there are a couple of giveaways. If a product is sold by the roll, like the roofing material in your local hardware store, it's probably asphalt. Another giveaway is the temperature rating. Asphalt melts at a lower temperature, so as you start seeing a lower temperature range – there's something else in there besides rubber.
So there you go – one of the sound deadening industry's dirty little secrets. Use the information how you will.
Back to Second Skin – if you're looking for an alternate sound deadening product to our mats, try one of our sound deadening liquids, Spectrum™ or the thicker Spectrum Sludge™. Both are water-based viscoelastic materials specifically formulated by Second Skin for high performance and easy workability. Yes, they work well. They're also easy to clean up with soap and water, environmentally friendly, and non-toxic. You just apply them differently. Spectrum™ is easy to spray, brush, or roll on. You can use it in place of our Damplifier products or in addition to them, because they can go places where it's hard to apply mats, like your vehicle's undercarriage and inside the wheel wells.
