Hi all,
I'm using foam board to insulate my roof. I lucked out and the thickness fits perfectly beside the ribs, however I'm wondering about the indentations in the roof (the opposite side of the aerodynamic "ribs"-I guess that's what you'd call them-that run lengthwise when you're looking at the top of the van from the outside, phew sorry I made that hard).
To restate-there's a skinny one inch wide gap every foot going across the width of the roof that the foam board obviously can't fill as it sits flush to the rest of the roof. I'm doubling up to have a R-value of 6, so is this a huge discrepancy that I should be worrying about? Or should I glue wool, fiberglass, or some other type of insulation to fill in.
