Factory-built metal chimneys must be avoided getting in touch with insulation by a minimal 75 mm (3 in.) unless otherwise specified by producer or neighborhood authorities.

A Biased View of Green Attics

A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encloses the electrical box.
