Dodo Mat DEADN Hex – 1.8mm Soundproofing Mat - Reduces Noise & Vibrations (30 Sheet Pack)

This is Dodo Mat’s premium sound deadening product, designed to reduce road noise and vibration in your campervan. It’s a direct alternative to brands like Silent Coat, Dynamat, and our own Kiravans Sound Blocker - but with a unique hex embossed aluminium finish and a slightly softer, more flexible feel during installation.

DEADN Hex is a 1.8mm thick, foil-backed butyl rubber mat that works by “deadening” the large flat metal panels in your van. That means less rattle, less hum, and a quieter ride — especially in the back of the van where metal panels tend to resonate at speed.

Features

• 30-sheet pack: covers 30 sq.ft (2.8 m²)
• 1.8mm thick – soft, flexible butyl rubber
• Hex embossed aluminium top layer for easier shaping
• Self-adhesive – just peel & stick
• Fire retardant & heat resistant (-40°C to +120°C)
• Water & oil resistant
• Non-bitumen formulation
• Individual sheet size: 375 x 250mm
• Pack weight: 7.5kg

Where should I use it?

Just like Kiravans Sound Blocker, DEADN Hex is most effective when applied to large, flat metal panels inside your van — for example:

• Side walls
• Rear doors
• Sliding door (yes, it fits behind the DoorStore!)

It’s less useful on floors, roofs, or wheel arches, which often have built-in ridges to reduce resonance already. Stick to the flat sections for best performance without adding unnecessary weight.

Installation Tips

• Use a roller for best adhesion
• Don’t apply over brackets or cable runs (especially in the sliding door)
• You don’t need 100% coverage — 60–80% of flat panel space is usually enough
• Fits behind the Kiravans DoorStore – we recommend 2 sheets per sliding door
