Image
Right – Blocking has been installed around the perimeter of this attic access to prevent insulation falling into the house
Image
Right – Several potential sources of air leakage into the attic have been air sealed; canned spray foam was used to seal around duct boots, along seams in the drywall, and along top plates.
Image
Right – The top plate-to-dry wall seams of the interior walls are sealed from the attic.
Image
Right – This attic knee wall and the floor joist cavity openings beneath it are being sealed and insulated with spray foam.
Image
Right-- IR photo shows how effectively spray foam insulated/air sealed attic kneewall and the floor cavities under kneewall
Image
Image
Seal the drywall to top-plate seams and the lower edge of baffles to the top plate to prevent the air coming from soffit vents from flowing under baffles into insulation.
Image
Second layer of rigid insulation is adhered with foam
Image
Image
Spray foam insulates and air-seals the ceiling deck and top plates of this vented attic.
Image
Spray foam insulation insulates and air seals around plumbing pipes and top plates in the attic.

Image
Spray foam insulation used for raised ceiling duct chase.
Image
The attic kneewall and the open floor cavities under kneewall are both sealed and insulated in one step with spray foam insulation
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
The missing top plate in a kneewall was covered with lumber and rigid foam insulation and then sealed with spray foam
Image
The polyethylene ceiling vapor barrier is sealed to form an air barrier around the exhaust fan in this very cold climate location (≥ CZ 6).
Image
The thermal boundary for a gable roof can be located at either a) the flat ceiling with a vented attic or b) the roof line for an unvented attic
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
Unvented roof assembly at eave retrofitted with rigid foam, spray foam, and a fully adhered membrane seal at the top of wall-to-roof transition
Image
Unvented roof assembly at rake retrofitted with a filler piece and taped top edge of existing house wrap or building paper to seal the top of wall-to-roof transition
Image
Image
Vented roof assembly at eave retrofitted with rigid foam, spray foam, and fully adhered membrane to air seal the top of wall-to-roof transition
Image
Vented roof assembly at rake retrofitted with spray foam and additional insulation installed at the attic floor and extended to the rake edge
Image
Wrong - Batt insulation does not provide complete coverage across the attic floor so ceiling joists are exposed resulting in thermal bridging.
Image

Image
Image
Wrong – No blocking installed to prevent attic insulation from falling into stairs and opening
Image
Image
Wrong: open wall cavity connected to this return air plenum is allowing cellulose attic insulation to be pulled into the furnace
Image
Wrong: This wall cavity is open to the attic allowing unconditioned, attic air to enter the HVAC system, bypassing the filter, and degrading system life and performance
