The Main Principles Of Green Attics

A heavy polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling frames the electric box. An electrical cord diverts from the electric box and down with an opening into an interior wall surface.

This proportion describes unobstructed vent area to the shielded ceiling location.


Also, do not make use of electrical exhaust fans for attic ventilation as these can draw extra air than can be provided with the soffit vents.
