Our DIY camper van conversion will be used as a winter splitboarding basecamp, so climate control is primordial. The thinsulate thermal insulation, the insulated window covers, the Webasto AirTop 2000 STC air heater and the Maxxair Fan are other key elements to make our campervan conversion comfortable during winter.
Choosing which type of insulation to use was one of the toughest decision; there is no perfect solution, therefore we went with the solution that was the best compromise for us.
The EZ Cool installation was performed progressively during the length of the conversion process, as we were installing the wall and ceiling. Why? Because if we covered the walls and ceiling too soon, we would loose the location of the existing holes for Cross Nut installation.
What’s the point of the EZ Cool?
We chose Thinsulate (check it on eBay) as our “main” thermal and noise insulation. To be effective, Thinsulate requires to be fully expanded: that’s almost 2 inches thick for SM600L Thinsulate. There are locations where we just don’t have that space to install Thinsulate (we rather keep that space as living area), so we installed EZ Cool.
Is it redundant to install Thinsulate AND EZ Cool? NO! Metal is an excellent thermal conductor, therefore leaving some metal exposed is really bad for thermal loss. We experienced it during our conversion: while we were in the Chic-Chocs at -15F, the Thinsulate surfaces were warm to the touch as opposed to the bare metal surfaces that were freezing cold. We lost a lot of heat there. That was enough to convince us.
Why did we install EZ Cool over the Thinsulate at some locations and some other not? The EZ Cool acts as a vapor barrier. We did not want to sandwich the Thinsulate between the van metal and the EZ Cool, to let it “breath”. We believe moisture will eventually get to Thinsulate (vapor barrier or not) so we covered about 75% of the Thinsulate surface. This is a compromise: this way we get some radiant shield properties of the EZ Cool and we let breath our Thinsulate.
TIME SPENT ON THE JOB
Really, it’s hard to tell because the EZ Cool was installed as the conversion progressed. It’s fairly easy and fast to install, so let’s say 4 to 8 hours total.
200$ USD, more or less

If you choose to only install the EZ Cool on the remaining exposed metal (following the Thinsulate installation), 200 Sq. Ft. should be enough. If you choose to cover the remaining exposed metal AND to install on top of the Thinsulate, you should probably get 400 Sq. Ft. (we are also using EZ Cool to make insulated window covers, so we went for the 400 Sq. Ft).

HERE IS HOW IT GOES
It’s not very complicated, so we will keep this short and sweet.
Similar to Thinsulate, we used 3M 90 Spray Adhesive on metal surfaces. For installation over the Thinsulate, we used the aluminum tape included with the EZ Cool.
ON SECOND THOUGHT
On second thought, we should have take more pictures of the EZ Cool installation!!

Hello! We’re Isabelle and Antoine 🙂 In 2017 we sold our house (and everything in it), quit our engineering careers and moved into our self built campervan. We’ve been on the road since then and every day is an opportunity for a new adventure; we’re chasing our dreams and hopefully it inspires others to do the same!
