Zoomed product image

Product Overview

This premium product offers two essential layers in one simple application. Designed as a thicker flooring underlay, this high-performance soundproofing and insulation mat features a heavier deadening layer and thicker insulation layer, making it ideal for vehicle floor and boot areas.

This twin pack covers 5 square meters for comprehensive floor coverage, effectively killing vibrations, blocking noise, and insulating the panels. The easy peel and stick application allows for a hassle-free installation onto the metalwork.

Sound Deadening Layer

The sound deadening layer is made from 2mm butyl rubber, designed to reduce vibration from the panel and act as a barrier to airborne noise. The composition with more rubber and less mineral filler enhances vibration damping and noise reduction significantly. Placing this on the metal floor of any vehicle will effectively eliminate unwanted vibrations and structural noise.

Insulation Layer

Featuring a 5mm closed cell foam insulation layer, this mat has excellent thermal and acoustic properties. It effectively reduces noise and insulates the vehicle, helping to stabilize cabin temperatures throughout the year and minimize condensation formation.

Convenience

The product is supplied in one continuous 5m sheet (rolled), perfect for custom work and large floor areas. This design enhances installation convenience, making it suitable for various applications.

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?
