Factory-built metal smokeshafts need to be kept from contacting insulation by a minimal 75 mm (3 in.) unless otherwise defined by maker or local authorities. Set up a non-flammable radiation guard that preserves a 75-mm (3-in.) air space in between the smokeshaft and insulation.

Getting The Green Attics To Work

The top of the radiation guard should additionally be a minimum of 75 mm (3 in.) more than the level of existing or brand-new insulation to be added.

The top of the barrier is a storm collar secured, not secured, to the chimney. Over the ceiling, the air and vapour obstacle is twisted around the drywall to get in touch with the firestop sealant.

The 15-Second Trick For Green Attics

A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encases the electric box.

There is commonly a gap in between the event wall (such as the shared wall between units in duplexes, triplexes and row houses) and the edge of the attic flooring.


A heavy polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling encases the electric box. An electric wire diverts from the electric box and down through an opening into an interior wall surface. Holes around electric cords are filled up with caulking Air conditioning repair or foam sealant, and caulking seals gaps along the top of the indoor wall surfaces.

Not known Factual Statements About Green Attics
