Frequently Asked Questions
Everything you need to know about sound deadening
How much sound deadening material do I need?
Coverage depends on your vehicle and goals. For basic noise reduction, cover 25-40% of each panel. For maximum results (audio builds, full insulation), aim for 60-80% coverage. Our team can advise on exact quantities for your vehicle — just get in touch.
Can I install sound deadening myself?
Absolutely. All our products are designed for DIY installation with peel-and-stick application. You'll need basic tools — a roller, utility knife, and clean surface. Most door panels take 30-60 minutes. We include installation tips with every order.
What's the difference between CLD, CCF and MLV?
CLD (Constrained Layer Damping) mats reduce vibration and panel resonance — the foundation layer. CCF (Closed Cell Foam) blocks airborne noise and adds thermal insulation. MLV (Mass Loaded Vinyl) is a dense barrier that blocks sound transmission. For best results, use all three in layers.
Do you offer trade or bulk discounts?
Yes! We offer competitive pricing for trade customers, van conversion businesses, and bulk buyers. Contact us with your requirements for a custom quote. Bundle deals are also available on our website.
