FAQ
What types of sound deadeners do you offer?
We carry butyl/aluminum mats, foam pads, spray-on deadeners, sound deadener tape, seam sealers, and full vehicle kits—engineered for use on floors, doors, trunks, roofs, and firewalls.
What benefits do sound deadeners provide?
They reduce road and wind noise, block engine and exhaust sounds, eliminate vibrations/rattles, and improve speaker and stereo clarity for a truly comfortable ride.
Where should I install sound deadening material?
Anywhere noise and vibration enter your cabin! Common spots are floor pans, doors, roof, firewall, trunk/cargo area, wheel wells, and behind interior trim.
Is it easy to install sound deadeners myself?
Yes! Most mats feature peel-and-stick backing for DIY application; simply clean the surface, cut to size, and press in place. Sprays and tapes are also user-friendly.
Can I use these materials with other insulation or heat barriers?
Absolutely. Combine sound deadeners with thermal insulation for even better results—great near the firewall, transmission tunnel, or exhaust.
Will sound deadeners add much weight to my car?
Automotive-grade deadeners are engineered to be lightweight while still effective. Most complete installs add only a few pounds per panel.
Are your sound deadeners resistant to heat and moisture?
Yes! Our materials are designed for high-heat, moisture, and automotive environments to ensure long-term durability.
What if my sound deadener doesn’t fit or arrives damaged?
Customer satisfaction is our priority. If your order is damaged or not suitable, contact us within 7 days for a prompt replacement, exchange, or refund.
