- Start by cutting an approximately good size piece of plastic for each section. For sections, we used the large beams already on the walls to dictate where we were going to separate the sections.
- For each section, start by using tuck tape on the top part of the piece to secure it in place.
- Then make sure to cut out space for the wheel for the bottom piece. Make sure the size is ok all around.
- Then tape down the bottom, and finish with the sides.
We had some more delicate cutting outs to do around the ceiling studs, and around the back anchor for the door. With some patience and good scissors, everything can be sealed out properly!
YOU ARE NOW DONE! The insulation for the van is complete. If you want a super extra good job, you can also add some insulation in the panels of the doors. We did not get to this part yet. You can also insulate around the wheels, but this has to be done in conjuncture with whatever you want to build around the wheels.
Once this is done, the next step will be to cover the insulation with a 'pretty' finish so that it is nice and welcoming to live in the van. Some people use thin plywood, some use plywood covered with fabric or rug. We are thinking of using thin cedar tongue-in-groove slats for a very nice finish. This will come in the next instructables tutorial!
As I said in the intro, this is the first van conversion we are working on. We do not claim that this is the best way to insulate the interior of a van, however we believe that we have done a thorough research of online resources and what we present here is a nice summary of the best options we have seen out there, considering our budget, our skills, our schedule, and our future use for the van (winter adventures!). We welcome all comments or questions, since we are curious to see how others have done it.
