Chris writes from Mount Holly, New Jersey: "I have an old farmhouse that has no exterior insulation. I'm adding insulation everywhere I can as I fix up the house. There is a finished 3rd floor with crawl space storage behind the knee walls. I have kraft faced fiberglass on the crawl space side of the knee walls between the joists (facing on the wall side). Because I am keeping stuff in the crawl space, though, I'd like to reduce the temperature extremes in there as well. The roof has a ridge and soffit vent system, so outside air can come right into the crawl space. I'd like to install FOAMULAR panels on top of the rafters, to maintain the vent system flow between them but keep the air out of the crawl space. Would this work?"
