We complete on a historic property next week. They are burning through $1000 of propane a month, the Building is brick, single, cavity then twin brick construction. We have about 3000sq ft of ceiling to insulate. Temperaturs can get down to -20F and the area is know for high winds. It is going to require a fair amount of work to the Building, but that is going to take at least a year, maybe two. In the meantime I need to do something about the ceilings. I was thinking that if I use Blown Fibre I could suck it back out when I need access to that area, and blow it back in later. Is there a better soluton?
