Product Description

This 35mm sound-absorbing foam sheet is a high-performance polyurethane foam material specifically formulated to achieve excellent sound absorption and flexibility. This versatile material excels at absorbing unwanted high frequencies, making it ideal for various applications. Its unique memory foam properties allow it to be effectively sandwiched between panels, filling gaps and enhancing sound quality.

After application, this sound-absorbing material effectively reduces echo and fills the spaces between surfaces. It can also be used behind speakers or within bass enclosures as a diffuser. The 'egg box' surface design increases the surface area available for absorbing sound.

Before You Start

  • Clean the surface with isopropyl alcohol or degreaser
  • Ensure the surface is completely dry
  • Work at room temperature (15°C+) for best adhesion
  • Have a roller and utility knife ready

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
  • Step 4: Use a roller to eliminate air bubbles and ensure full contact
  • Step 5: For CLD mats, overlap edges slightly for complete coverage

Pro Tips

  • For CLD mats: 60-80% coverage gives 95% of the benefit
  • Focus on the centre of large flat panels
  • Apply CLD first, then CCF/MLV, then acoustic foam
  • Use a heat gun in cold conditions to improve adhesion

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.
