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.

Try to keep in a straight line, harder when you go to add the second layer as you want there to be minimal gaps in between.I’d read that it was best to fit the super liner width ways as it’s easier to fit over the bumps in the floor instead of doing length ways. This was good advice, I could see how doing length ways would be really awkward. Use a special formulation closed cell foam with excellent thermal and acoustic properties. Ideal to reduce noise, insulate the vehicle and to isolate barriers and trim panels. For the ceiling of my Vauxhall Vivaro Mk3 I used approximately 2.5-metres of thermal linerinsulation, less because I was filling the panels in the ceiling and not covering the entire area. Total = 2.5 m2 The instructions within the box suggest up to 50% of each panel is covered and for areas that have more noise, for example, the wheel arches they have 100% coverage. I adopted this suggestion (sort of).

I started with the thermal liner which came on a 10-metre roll and I used a tape measureto roughly work out the size I needed for each panel and cut this with my heavy duty scissors. Once I had a smaller piece to work with I found the best technique was pushing the thermal liner into the curved corners, bending it down then cutting to create the shape. Again, this didn’t need to be perfect but I was aiming for maximum coverage. 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. 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. One of my first jobs on Dennis (my van) was my insulation, firstly, that’s because how it works with a van and secondly, I wanted to do a few trips away and since it was still winter/early spring in the UK I wanted to be warm.

When treating a typical van or camper you must use a number of different products to achieve an excellent final result. Many camper van projects start life with very limited luxury, however the interior can be improved dramatically with the application of good sound deadening and insulation. How Much Does A Campervan Conversion Cost? (Vauxhall Vivaro Mk3 LWB) How much did the sound deadening cost?

I also researched that you needed to measure and cut extra to allow for the bumps, I added about 30 mm to my first measurement, which was slightly too but but better being that way than too short. There’s an abundance of information about the best insulation for campervans out there, so a lot of my choices were based researching what was right for me, based on my skill level for fitting and also my budget available. I also kept all the odds and ends so I could use every bit of the thermal liner on any odd places once I’d done the large sections. For my side panels and four doors I used the same two items for my van insulation – Dodo Mat thermal linerand recycled plastic loft insulation I have planned to add another type of insulation in the gaps but I’m yet to work out what’s right. It’s too expensive to buy another roll when I’d only be using 1-metre at the most. Watch this space for an update.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. Your van is essentially a metal box! Metal conducts both heat and cold, therefore when it’s cold outside your van will mirror the temperature. I started staying in my van during March in the UK, I had temperatures of minus 6 at night, maybe colder and I can confirm that insulation made a HUGE difference. I woke up one morning with ice inside my van on the exposed metal sections, but the insulated areas were a normal temperature to touch by hand. What did I use to insulate my van? I fitted mine on a warm day and rubbed my hands over them to warm them up. Sound deadening sheets + roller to secure in place Was 30 sheets enough for my Vauxhall Vivaro Mk3? The Dodo Mat Super linercame as a 6-metre roll, measuring 500 mm wide, therefore covering a total of 3 metre squared. I’d roughly in my head thought it would be enough, but in reality it came up a little short for my van. In hindsight, my van measures 2.5-metres x 1.3 metres so I failed on the maths there! Your decision on insulation will initially be based on the type of van you have. For example, insulation boards look a great option, however, for a small van conversion it might not be the best choice. You’d need to create a framework to place the insulation boards into (that’s what the ones I’ve watched have done), which then would reduce the headroom available in your van.
