Zoomed product image

Product Overview

This unique product offers two essential layers in one simple application. With soundproofing and insulation combined, this mat will kill vibrations, block noise, and insulate the panels. Simply peel and stick onto the metalwork for an easy application.

Sound Deadening Layer

This mat features a 1.5mm butyl rubber deadening layer that effectively reduces vibration from the panel and acts as a barrier to airborne noise. More rubber and less mineral filler means better vibration damping and noise reduction. Placing this mat on the metal panels of any vehicle will significantly reduce unwanted vibrations and structural noise.

Insulation Layer

The product includes an integral 3mm closed-cell foam insulation layer with excellent thermal and acoustic properties. This layer is ideal for reducing noise and insulating the vehicle, helping to stabilise cabin temperatures throughout the year and reducing the chances of condensation forming.

Convenience

To increase installation convenience, the product is supplied in one continuous 5m sheet (rolled), perfect for custom work and larger areas.

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.
How fast is delivery?
Orders placed before 2pm are dispatched within 1-2 working days. Once dispatched, transit typically takes a further 2-4 working days. Total delivery time is usually 3-6 working days from when you place your order. Delivery is a flat £9.99 to any UK address. We ship nationwide across the UK.
Can I return products if they're not suitable?
Yes, we offer a 14-day return policy on any order, for any reason, and you may open and inspect it first. Please contact our team to arrange a return. Return postage is yours unless the item is faulty. Items cut to your specification are non-returnable unless faulty.
