Sound & Thermal Insulation; What to use and where! What do I need to know?

Updated: Nov 9

Starting your build off with some very simply installation advice is always a result! We aim to list a few generic areas and products which suit best. Of course there are lots of ways to complete any build and its not always as easy as a exact fit.

Some people talk of using Celotex or PIR boards, of course this is an option for some builds, many like to use automotive products. We looked this topic here to inform installers and self builders to consider all options.

We have a wide variety of products which suit most budgets online. If you are looking for a budget installation, we now stock Dodo Dead-Ezy which is a budget product new release worth looking at.

If a Crafter or large vehicle is your build, we have a few best fit packages too. We can usually offer a discount on larger packages so always worth getting in touch with us albeit our prices tend to be the best available.


The most common product we sell is Silent Coat. This is a butyl deadening fitted first which will stop panel bounce and resonation. If youre adding Thermo Liner Pro, you can usually drop coverage down to 50-60% for best the outcome, again you need to consider weight and cost. Once you have chosen your deadening package you can move on to choosing your insulation package suitable for the use of the vehicle. Its important to know the difference between sound deadening and insulation with the impacts they have on sound and heat isolation. We covered this here


The same advice applies here to the sides, obviously you need to consider if you are installing a pop top on small vans as to the amount of insulation to add. It is not unhead of to use a thicker liner on the roof to reduce heat loss and the thinner on the sides to save weight.


This is where budget comes in to play. The best setup would be to use Dodo Duo. This comes in 4.5mm and 7mm and can be used to save on height, especially around a build with an interior kitchens and units similar to a Crafter. Dodo Deadn Duo is a multi use product which combines Dodo Hex Sound Deadening with Dodo Super Liner to give an acoustic and thermal isolation all in one product.

A cheaper option is to use either a butyl deadening alone on the floor rather than Dodo Duo such as Silent Coat or Super Liner

Cab area

This is an area which is missed out the most being an additional cost and extra work to remove the carpet and front seats. A 30 pack of Silent Coat is usually enough to cover the area with a small amount of liner on the roof area to reduce heat loss. There will be a surprising amount of condensation under the cab lining when removed so its alwasy an area worth installing!

What is really important for any build is to consider the cost, weight and coverage...
