Havelock Wool – Improves indoor air quality, manages moisture, absorbs sound.
Polyisocynurate Foam Board – PolyIso has the highest R-value per inch of any rigid board insulation. We installed this on the ceiling and window panels along the sides of the van.
Spray Foam – The rocker panels in the Promaster are known for water getting in. We really wanted to use wool throughout our whole build but after it rained we ended up taking out the wool from the rocker panels to check, and it was indeed wet. So we used spray foam instead to fill all the rocker panels and to act as a sealant.
Kilmat Sound Deadening – We put kilmat on the ceiling to help reduce rain noise. You will need a roller for this product, you can get the one we used here.
Bubble Reflectix – We used reflectix as an extra layer and vapor barrior on top of all the insulation. We also put this under our subfloor instead of foam to save the most headroom space. If we used foam board on the floor and ceiling, Ethan wouldn’t be able to stand up straight (he’s 5’8).
Silicone – We wanted to keep water out as much as possible. We used silicone throughout the van whenever we saw a hole. If you have a Promaster be sure to check around the wheel wells and seal anywhere you can see daylight.
Spray Adhesive – We used this to stick the foam, wool and reflectix on the walls, ceiling and floor.
Rustoleum – When we were pulling off the wall panels that came in the van, it left behind some scratches. We painted any bare metal showing throughout the van so no rust occurs.
