Zoomed product image

Product Overview

This premium 35mm acoustic foam is a high-performance polyurethane material designed to achieve superb sound absorption and flexibility. It is specifically formulated to absorb unwanted high frequencies, making it an ideal solution for a wide range of applications.

Utilising pressure-sensitive properties, the foam can be effectively sandwiched between panels, filling gaps and enhancing sound insulation. It is ideal for use behind speakers or inside bass enclosures as a diffuser, improving sound quality in any setting. The profiled 'egg box' surface increases the exposed surface area compared with a plain flat sheet, which helps it absorb more sound.

Application Steps

  • Step 1: Measure and cut the material to size
  • Step 2: Peel back the release paper
  • Step 3: Press firmly onto the clean surface

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.
