How To Insulate A Campervan
Posted in: Guides, Insulation

If you have just bought or are thinking of buying a campervan to enjoy road trips and travelling around the world in, you’ll need to consider how you’re going to go about insulating it. You’ll want to make sure it remains at just the right temperature no matter what time of year it is.


When people think of insulation, they tend to just think about keeping things warm in the winter months, but it’s also about keeping the space cool in the summer months too. There’s nothing worse than having an uninsulated van when travelling around the UK, as you’re going to struggle to get a good night’s sleep.


Luckily for you, the experts at Insulation Express are here to let you know the steps you will need to take.


Things To Consider


When insulating your campervan, you’ll need to make sure you plan for some kind of vapour barrier to allow moisture to escape. This is particularly important if you’re going to be cooking meals like pasta and rice on a hob, where steam and moisture build up.


If there’s no ventilation, the moisture will build up and turn into condensation on the windows and walls.


It goes without saying that people breathing in the van will also contribute to condensation build up, so planning for a vapour barrier is a must.




What Materials Will You Need For Campervan Insulation?


To help with saving space when you don’t want the insulation to take up loads of room, multifoil insulation is a great option. If you buy a roll such as Euroform 2 BDA U Foil which is unaffected by moisture and condensation, it should make things a lot easier for you. The good thing is that it’s also flexible and easy to fit, so you won’t need to stress yourself out when installing it.


As well as the multifoil insulation, it’s important to fill any larger cavities that remain with glass wool insulation, to make sure there are no gaps for heat to escape from. The great thing about glass wool insulation is that it’s cheap and very efficient. You need to remember to keep it covered properly as the fibres can be extremely itchy, both to touch and directly breathe in.


Should I Layer Over Campervan Insulation?


When insulating a van, internal panels will need to be removed for the insulation to be added before the panels are then put back into place. Problems can occur while doing this though, as some panels may be tough to remove, or you may end up breaking one or two of them.


No need to panic though, as you can create a low-cost replacement with some plywood that you can cut to size and cover over the insulation.


How To Fit Campervan Insulation


Not sure how to install insulation into your campervan? Follow our step by step guide:


  1. Take any furniture or fixings out of the van to give yourself as much space as possible to work with.
  2. Take away the existing panels on the van walls, making sure you keep all of the relevant screws and fixings together.
  3. Tape some foil insulation into place on the walls of the van, making sure there’s a tight seal with tape around corners, wheel arches and any protrusions.
  4. Make sure a vapour barrier is installed if there isn’t one already built in.
  5. Replace the wall panels with the original screws and fixings.
  6. Fit any carpets, lights and furniture that were removed back into place.


After following these steps, you can enjoy the benefits of having insulation in your campervan, such as keeping the van cool in the summer and retaining heat in the winter.
