How To Choose The Best Insulations for Camper Vans
Choosing the best camper van insulation is no easy task. There are many considerations to think of, and the followings are some of the most important ones!
Ease of Use
Installing insulation can be a time-consuming process. If you want to skip the hassle, you can get wool and fabric insulations. They’re easy to squish in the walls, and you can cut them into small pieces effortlessly. Using spray insulation can also save you energy and time. On the other hand, Celotex and polystyrene materials are harder to install.
Safety
Just because it doesn’t go inside your body doesn’t mean your insulation is safe. So, make sure the material of your insulation is toxin-free and won’t become toxic as time goes by. Also, you may consider getting fire retardant insulation!
Cost
As affordable as it gets, your favorite insulation will still cost you a significant amount of money, especially if you have a big camper van. Our advice is not to think too much about which is cheaper or more expensive. Instead, focus on the quality of the insulation. But if you want the cheapest option, foam board is the way to go.
Should I insulate my camper van floor?
Why not? Insulating your camper van floor can significantly decrease the total heat loss.
How do you stay warm sleeping in a van?
Well, you can stay warm by using your favorite heated blanket or getting the best fireplace for campers. But nothing is effective as installing the best insulation for camper vans!
Is it worth insulating a campervan?
Yes, it is! Keeping your camper van well insulated is a must. It can keep you toasty on freezing nights while you’re camping and stop the temperature from getting too hot during those summer days.
