I am having my crawl space sealed with a vapor barrior have have a queation regarding insulation. I am going to seal up the vents and install insualtion on the walls. What is bettter, radiant reflective insulation or fiberglass?
Id never use fiberglass in there if there was any type of moisture issue. Use extruded foamboard instead (pink or blue) for the walls as wont be ruined if theres a moisture issue. The radiant reflective stuff is a waste of money imo. You wont much radiant heat build up down there and thats what its designed to prevent.
