Before framing interior non load bearing perimeter and partition walls we applied Pro Clima Intello fabric to the bottom of the roof joists which was affixed to the parged walls with Pro Clima tapes and caulks. This creates an air tight, water tight and vapor open barrier. Above this membrane and between the roof joists we will place eight (8) inches of dense pack cellulose. Since the original masonry walls themselves are not plumb or straight by current standards we stood off the perimeter walls sufficiently to insure a plumb and square interior finish. Behind the perimeter walls, dense pack cellulose will be applied at thicknesses in accordance with our PHPP model.
