Our sound-deadening mats use butyl rubber with an aluminium foil facing and pressure-sensitive adhesive to tame panel vibration in doors, floors and trunks. Choosing the right thickness (e.g., 2 mm) and installing it properly can markedly reduce resonance, improve audio clarity and cabin comfort. Apply to a clean, degreased surface and roll firmly to seal edges.

Brief Summary & Key Benefits
Sound-deadening mats primarily reduce panel vibration, lowering structure-borne and road noise. Butyl-rubber sheets with an aluminium foil facing bond to doors, floors and trunks to damp resonance, yielding cleaner audio and a calmer cabin. Advantages include durable adhesion, resistance to moisture/oil and easy forming. With smart coverage, you can achieve audible dB reductions without excessive weight.
Technical Basics
Most products use butyl rubber (not bitumen) plus an aluminium top layer. Butyl stays stable across wide temperature ranges (-30…+80 °C) and provides long-term tack. The foil stiffens the sheet, acts as a vapour barrier and improves rolling. Typical thickness is 1.6–2.5 mm; around 2 mm offers an excellent balance for large areas. Damping works by increasing the panel’s loss factor—mechanical energy is dissipated as heat within the viscoelastic butyl under shear.
Complementary layers include closed-cell foams (PE/EPDM) at 5–10 mm to decouple trim and tame squeaks, plus thin felts for extra absorption. Always bond butyl directly to the metal, with foam on top if needed. Over-thick foam behind door cards can impede closing and leave pressure marks.
Common targets: outer door skin, inner service-hole areas, rear wheel wells, trunk floor, quarter panels, tunnel and cabin-side firewall (observe heat limits).
Selection Criteria
Material: choose odour-free butyl; avoid bitumen in high-heat environments. Foil thickness affects stiffness and ease of shaping.
Thickness & mass: 2 mm suits most doors and floors; go 2.5 mm for very thin or lively panels. Expect ~3–3.5 kg/m²; plan the project weight budget.
Substrate: clean, rust-free metal is essential; poor paint needs prep and corrosion treatment first.
Thermal exposure: near hot zones (firewall, exhaust paths) respect rated °C, add heat shielding and ensure sealed edges for splash areas.
Goal: for audio clarity, prioritise doors (outer skin + inner panel reinforcement). For road-noise cuts, treat floor, wheel wells and trunk for the biggest gains.
Installation & Maintenance
1) Prep: thorough cleaning and degreasing (IPA). Light scuff if needed, then dust-free wipe-down. Repair any corrosion first.
2) Apply: peel liner, press from centre outward, then roll firmly with a pressure roller. Gentle heat helps on tight curves—avoid overheating.
3) Seams: overlap 5–10 mm or butt-join cleanly; seal edges to keep moisture out.
4) Layering: butyl to metal; foam on top where needed. Verify clearance for linkages and window travel in doors.
5) Verify: tap-test for tonal change; add material where the panel still “rings”. Periodically check edge adhesion and re-roll if required.
FAQ
Q: How much door coverage is enough?
A: Treating the key resonance zones—about 25–40%—often yields strong damping. Full skin coverage adds weight with diminishing returns.
Q: Do I need heat to apply?
A: Not strictly, but gentle warmth aids conformance. Avoid excessive temperatures.
Q: Why won’t it stick?
A: Typically insufficient degreasing or dust. Re-clean and roll with high pressure.
Q: Is bitumen OK?
A: We don’t recommend it for large cabin areas due to heat softening and odour risk.
Q: How much weight will it add?
A: Around 3–3.5 kg/m² for 2 mm sheets; target high-return panels first for best benefit-to-mass ratio.
