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. We avoid asphalt entirely because we don't mess around with the health concerns, but we would strongly discourage you from using those cheap sound deadening products if you live in a warmer climate. Asphalt will melt and out gas chemicals at high temperatures. Avoid the sticky mess and the fumes. Keep asphalt on your roof or on the road, not inside your 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 probably contains asphalt. Another giveaway is the temperature rating. Asphalt melts at a lower temperature than rubber, so as you start seeing a lower temperature range – the sound deadening material has cheaper fillers in at best, but probably contains asphalt.
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 a sound deadening spray like 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.
