To fill all the gaps/panels in my van I used two and a half rolls of loft insulation, each roll covers 2.22 m2. I bought two rolls and I had a friend that had some spare which is why I only needed to buy two. Total = 5.5 m2 My van is a medium sized van, long-wheel based, approximately 2.5 m long by 1.4 m wide and 1.4 m high, to help you visualise and compare to your van. As soon as I removed all my plywood panels and the bulkhead the noise of the van during normal driving was apparent, all those speed bumps or potholes caused even more noise and rattling of the metal, that was noisy even with the music on. I’ll break down my insulation into the three main areas I fitted it to – the side panels and doors, the floor and the ceiling. Ceiling insulation

When installed in your vehicle Dodo Super Liner will act as a thermal insulating layer to help stabilise vehicle cabin temperatures throughout the year. To prevent cold air being drawn up from under the van, a layer of closed cell foam underlay will help insulate the floor while keeping the profile low to allow ply and side steps to be refitted. The foam will also prevent the ply from "creaking" and act as a floating layer.

Dodo Super Liner

Use on all metal panels up to 50% coverage for most cost effective results, or 100% on outer panels for a fully comprehensive job. This product can be used on any metal panel in your vehicle, with the most common areas to treat being the sides, wheel arches, roof and bulkhead. You may also add deadening to the floor if required, however the floor pan generally suffers least from vibration issues and will use a lot of extra material. I put one full sheet on every single panel inside the van, minus the two panels that I’d since had windows fitted in. For the wall panels, this was 4 on the side panels, 4 on the side doors and 1 on the barn doors, so a total of 9 sheets used. Dodo Super Liner is an affordable, self-adhesive flexible foam liner that is perfect for vehicle heat and sound insulation when applied over sound deadening. The unique Dodo closed-cell foam formulation has been designed to give superb thermal insulation and acoustic absorption in a low 6mm (1/4″) profile. This self adhesive high quality liner can maintain shape under pressure yet be flexible enough to trim easily in many areas of the vehicle. It is water and high temperature resistant and flame retardant to UK vehicle standards. We recommend a simple easy to follow "2 stage process", applying a panel deadening product first, followed by quality insulation over the top. Stage 1 - Sides, roof and doors

Here I’ll explain which insulation I used for each part of my campervan, mission, to keep ‘Dennis’ lovely and warm 🙂 Campervan Sound DeadeningFor all the tools I’m using for this van conversion you can see the full list here.
