Sound Deadening & Insulation Kit - MWB Large Van (eg. VW Crafter MWB)

In stock
Product Details

One of the first and most important stages for any van conversion is taking that bare panel van and creating a warm and condensation free base. There are three main stages to achieve this - Sound Deadening, Thermo Acoustic Liner and Insulation.

In our Crux & Bespoke conversions we've been using the Dodo Mat range of products and have now created kits based on van sizes to make it easy for the self-build convertor. Whilst the subject of sound deadening and insulation has many theories and opinions, this is our recommended method (based on experience) and what we use in our builds.

Sound Deadening - Dodo Mat DEADN Hex Sheets

Supplied in small sheets with self-adhesive backing, the 1.8mm butyl backed foil sheets stick to any flat outer skin panel and reduce unwanted vibrations & structural noise. Approx. 60% coverage on flat panels, we also advise fully covering the wheel arches to reduce road noise. See more technical info from Dodo Mat below.

Thermo Acoustic Layer - Dodo Thermo Liner 6mm

Dodo Thermo Liner is a high grade foil lined XPE closed cell foam which is applied to all outer skin panels. Supplied on a roll and easily cut with a knife, it's a 6mm sound and heat insulation material for a quieter & warmer van and prevents condensation build up on the van's bodywork. See more technical info from Dodo Mat below.

Insulation - Dodo Thermo Fleece 50mm

Supplied in 390mm wide x 10m long rolls, Thermo Fleece by Dodo Mat is an itch-free sustainable insulation quilt manufactured from recycled plastic bottles. Simply tear off to the required length and fill into any voids. When fitting to the roof and flat sides, apply a small amount of heat resistant adhesive (eg. Trimfix) to hold in place. See more technical info from Dodo Mat below.

Optional - Flooring - Dodo Super Liner 6mm

There are many different methods for insulating under the floor (which is very important) and we've left this as optional. On our vans, we fit strips of the Dodo Super Liner on the lower section of the floor ribs. Our flooring panels (which also contain insulation) are then bonded directly to the top surface of the floor ribs. See more technical info from Dodo Mat below.

We also have the option to upgrade the Thermo Liner to Thermo Liner Pro in 6, 10 or 12mm thickness - please contact us if this is required.

If you want us to fit the products, we also offer this service too. Please get in touch to book a slot at our workshop in Bordon, Hampshire.

The quantities of our kits are based on our experience of fitting these products to various vans and makes the assumption that a couple of windows are fitted in the rear of the van. This is a recommendation/guide - if you know you have more/less panels to cover (eg extra high roof or windows all round) please add extra material from our individual listings).

The technical info from Dodo Mat

Dodo Mat DEADN Hex is a self adhesive, foil backed sound deadening vibration damper. Simply cut, peel & stick Dodo Mat DEADN Hex on the interior sheet metal of any vehicle to recuce unwanted vibrations & structural noise.
Make those panels as dead as a Dodo!

Dodo Mat DEADN Hex has a high grade butyl compound for better sound deadening & vibration control. To maintain flexibility and ease of cutting we also employ our unique Hex embossing pattern.

Dodo Mat DEADN Hex provides a lower weight solution for the car/van owner wanting a quiet smoother drive without adding unnecessary mass. The unique Dodo specification chemistry of the synthetic butyl core effectively deadens panel vibration without the excessive bulk of competitor products.

The distinctive Hex top sheet is purposely designed to be aid installation and mould easily on more complex surfaces. This added flexibility allows the Dodo mat to be easily installed, with improved cosmetic appearance whilst minimising creases and folds.
