I have an 8x10 room in my basement I'm converting to make snake room. Living in New England my concerns are heating for the winter. 2 of the 4 walls are blocks so how do I go about insulating? Can I attach foam insulation board? I saw rolls if this insulation foil would that work? I thought about framing the walls but there's pipes all over the ceiling that would prevent me from doing that? How should I proceed? This is what I have to work with..
