Image
The batt insulation shown here was properly installed to fill the ceiling cavities.
Image
The builder installed this OSB under the roof rafters and air sealed the seams with tape then added a dropped drywall ceiling to provide a service cavity for ducts and wiring, while minimizing holes into the attic.
Image
Image
The drywall above the chase extends beyond adjoining top plates for a continuous air barrier

Image
The rim joists and top plates are air sealed and insulated with open-cell spray foam while the walls are filled with blown fiberglass.
Image
The seams in the ceiling drywall are sealed from the attic side with spray foam.
Image
The soffit dam and baffle allow air to flow through the vents without disturbing the insulation covering the top plates
Image
The unvented attic is insulated along the underside of the roof deck with 7 inches (R-49) of closed-cell spray foam, providing vaulted ceilings and a conditioned knee wall space for ducting.
Image
The walls and ceilings of this post-and-beam home are filled with netted blown fiberglass.
Image
There are three potential locations for an attic radiant barrier – adhered to the underside of the roof decking, hanging from the rafters, or on the ceiling insulation

This builder applied an air-sealing layer of spray foam along the underside of the roof deck and the inside of the walls before filling the wall cavities with blown cellulose.
Image
This finished retrofit installation of radiant barrier in attic shows the air spaces at the soffit and ridge to promote attic ventilation
Image
This kneewall has no top plate and the resulting gap provides a wide-open pathway for air and vapor to travel between the living space and the attic
Image
This typical dropped ceiling hallway chase shows a complicated air sealing scheme where chase ceiling drywall meets sidewall top plates
Image

Image
Image
Wrong - Batt insulation does not provide complete coverage across the attic floor so ceiling joists are exposed resulting in thermal bridging.
