Premium Sound Blocker 2,5 mm

Heavy-Duty Campervan Sound Deadening – Sold by the Metre

Premium Sound Blocker 2.5 mm from Eaglefelt is a high-density,
self-adhesive butyl sound deadening mat engineered for superior
vibration control in campervans, motorhomes and panel vans.

Supplied by the metre from continuous rolls, this professional
van soundproofing material allows you to purchase the exact quantity required
for your conversion project, reducing waste and improving installation efficiency.

At 2.5 mm thick, this upgraded vibration damping mat delivers
even greater mass and acoustic performance — targeting large, flat metal panels
to eliminate resonance, reduce road noise and remove the hollow “tinny” sound
common in uninsulated vans.

Why Choose Premium Sound Blocker 2.5 mm?

Flat van body panels naturally amplify tyre and road vibration. The increased
thickness of the 2.5 mm version provides enhanced damping performance compared
to standard 2 mm materials.

• Extra mass for improved vibration damping
• Reduces panel resonance and drumming
• Lowers road and tyre noise inside the cabin
• Improves overall driving comfort
• Supplied on rolls and sold by the metre for flexible fitting

The advanced butyl rubber layer absorbs structural vibration, while the
reinforced aluminium constraining layer converts movement into low-level heat,
preventing resonance from becoming airborne noise.
