Having lived in our 1996 roadtrek for two years prior to our Promaster we have experienced what type of environments we typically spend time in. We tend to spend most of our time in milder climates, nights barely getting below 30 degrees and days no hotter than 80. Therefore, we decided against installing an AC unit or a heating element instead opting for heavy duty insulation. Touch N’ Foam Polyurethane 2- Component Spray Foam Kit from Home Depot was the product we used. Spray foam creates a layer directly next to the sheet metal that prevents condensation which in turn prevents molds, mildews and rust forming. Another reason we chose spray foam was one inch of foam has an R-7 value. We sprayed anywhere between two to three inches.
Thus, our whole van is insulated anywhere between R14-R21 value. To put that into perspective houses are typically insulated around R19. Beware of spraying to fast and too heavy as this has been known to warp the sides of the van. Spray multiple thin layers allowing each to dry prior to spraying the following layer. This will prevent the van walls from warping.
Step 1: Tape off everything!
Using Frog Tape, tape off everything you don’t want spray foam on. This stuff is messy and it will be better in the long run to just take the time to tape and plastic everything off. We taped off our whole front of the van with our seats, all of our wiring, the floor, wheel wells, and the windows. The wheel wells and windows you’ll insulate later after your sub-wall is installed.
Step 2: Spray Away!
Follow the Spray Foams instructions and spray away!!
Step 3: Use Great Stuff spray insulation for the smaller cracks and dead spaces in the sliding doors.
Step 4: Let Dry and Scrape
After the foam has had time to cure you’ll want to scrape away any excess foam off of the high ribs of the van. You’ll need the ribs to be clean to anchor the furring strips to.
Pro Tip: Insulate the dead space in your back doors with Pink Panther insulation. This will make it significantly easier if you ever have to get to your wiring for your back up lights.
