Product Description:
Dodo Mat DEADN DUO Pro is a unique two-in-one product that combines vibration damping with insulation in a single application. The Pro version is specifically designed as a thicker flooring underlay, with a heavier deadening base and a thicker insulation layer – perfect for serious soundproofing and thermal control in vehicles.
This twin pack provides 5m² coverage, making it ideal for full campervan or motorhome floor treatments. Simply cut, peel and stick the sheets onto your vehicle’s metalwork for instant noise reduction, vibration control and insulation in one easy step.
 
Sound Deadening Layer:
The base layer of DEADN DUO Pro uses a dense 2mm butyl rubber sheet. This material reduces resonance, vibrations and rattles while acting as an effective barrier against airborne noise. With more pure butyl and fewer mineral fillers than cheaper mats, it delivers superior vibration damping and long-lasting performance.
 
Insulation Layer:
Bonded to the deadening base is a 5mm layer of Dodo Super Liner closed cell foam. This integral insulation layer provides excellent thermal and acoustic properties, helping stabilise cabin temperatures throughout the year while reducing noise. Its closed cell structure also minimises condensation risk, making it ideal for campervans, motorhomes and vehicle floor areas.
 
Convenience:
Supplied as two continuous rolls (50cm x 500cm each), DEADN DUO Pro is designed for easy installation across large floor areas. The flexible design requires no heating, is simple to cut to size and moulds easily to the contours of the vehicle.
