I am building a new house and I would like to cut the 4x8 sheets of solid foam insulation to place between the rafters in the attic, instead of using batts. Does solid foam insulation have to be covered on both sides? How fire resistant is it? The purpose of using solid foam is to cut down on dust in the house, since I live in the dusty and hot desert southwest. Spray-in insulation is not an option. Any opinions would be appreciated. Thanks. Bonnie
White is poison to a picture! Use it only in highlights.
Peter Paul Rubens. 1577-1640.
I would add: don't use white in architecture either, except rarely and sparingly.
