Insulating a van conversion

Your van conversion

If you’re reading this, I see you need more than a tent. Firstly you need to start by stripping your van out so there is nothing left in the back. Once this step is done you are onto the arguably most important step, insulation… Have we got the perfect product for you?  We believe that our Therma-Foil, foil insulation is the best for your conversion. Read this post for proof.

Insulating your van

Insulating your van is very important and can make or break the conversion. With the correct insulation, you can stay warm in the winter and cool in the summer. Therma-Foil is specifically designed for floors and walls and would be perfect for your van. It’s only 2.5mm thick, which means that you won’t have to worry about your insulation taking up loads of space.

Therma-foil has also got great noise dampening a minimum of 18db which will be helpful if on a campsite and you don’t want people to hear you as easily, because everyone loves privacy, but once thing we love more is to be nosey and listen in to what people are talking about.

Our foil isolation is also extremely light, a 25sq meter roll only weighing 3kg. When Converting you need to save on weight where possible, and this is a great way of doing so.

Keeping warm on those cold winter nights are very important, especially in a van where there is no heating. I do a lot of camping and when it is a cold night it is horrible and I wish I had extra insulation. When converting a van you can make sure that you have enough to stay warm in winter (or summer we are in Britain, it’s cold all year round).

Alternatively, when we do get a little bit of heat in this country, it is amazing. I don’t know about you, but one thing I hate more than sleeping cold is going to sleep hot and sweaty. When using Therma-Foil, foil insulation of great quality it has is not only keeping the heat in winter but reflecting the heat outside on hot days so that you can be comfy and fall asleep cool.
