Van Insulation

If you want to stay comfortable in your van no matter the weather, there is need of van insulation. van insulation is one of the most important steps of any van build, and it pays to take the time to do it right.

There’s also a lot of confusion and debate over the best way to insulate a campervan, and it can be tough to wade through all the opinions and figure out what to do.

Insulating inside your van’s hollow frame can help reduce the effect of thermal bridging. If you spend a lot of time in very cold weather.

It might be a good idea to put up thermal breaks, which are basically non-conductive materials (i.e. insulation) placed in the pathway of a thermal bridge to block the flow of heat. If you put up additional insulation on top of your van’s ribs, that would be a thermal break.

Another way to ensure proper insulation is by creating insulated window covers. This is the area where warm or cold air will most likely infiltrate your van.

One of the easiest ways to create DIY window covers is by using reflectix as the form of internal insulation. It can be easily glued or sewn between materials. Consider using a heavier material for the outside, such as canvas or water-resistant duck cloth.

Inevitably, once you are done insulating your van, there will be areas too small for the larger forms of insulation.

One of the best options for filling in small details and tiny cracks is “Great Stuff,” an insulating foam sealant. It’s easy to apply and is especially useful for filling in the tight areas around door and window frames. Keep in mind – it will likely require many, many cans.

You want to make sure the van is warm in the winter and cool in the summer. You want to reduce the risk of condensation forming in the van, and on metal surfaces which could lead to rust. You will also want to reduce sound transmission and road noise.

he most common insulating materials available are normal insulation. Rigid foam (PIR Insulation), or wool insulation (glasswool, rockwool or sheepswool), rubber foam (like thick swimming float), but my personal favourite is Low-E Insulation, a high-spec reflective foil with a recycled closed cell foam core.
