Cut-away view showing unsealed gaps around a heating duct that goes through a wall
Image
Install a sealed enclosure over a non-IC rated recessed light fixture to air-seal the can and to prevent insulation from touching the recessed can light.
Image
Image
Right - A “flash” seal approach with spray foam provides a continuous air barrier between the ceiling and walls of the garage and the living space.
Image
Right – Closed-cell spray foam insulates and air-seals the rim joist above a shared wall between the garage and living space.
Image
Right – Joists between floors are air sealed to the ceiling drywall with canned spray foam along each joist-to-drywall-seam.
Image
Right – Spray foam insulates the walls and ceilings separating the garage from the home.
Image
Right – The insulating enclosure over this non-IC rated recessed light fixture is centered and air sealed
Image
Right – The top of the enclosure over this recessed can light remains clear of attic insulation
Image
Right-- IR photo shows how effectively spray foam insulated/air sealed attic kneewall and the floor cavities under kneewall
Image
Rigid foam insulating sheathing installed over an existing garage ceiling with retrofits to air seal exterior wall before adding exterior wall insulating sheathing
Image
Rigid foam insulating sheathing is installed on existing garage ceiling and covered with a new gypsum board fire protection layer installed over the foam.
Image
Spray foam insulates and air-seals the ceiling deck and top plates of this vented attic.
Image
Spray foam insulates the top plates and air seals them to the ventilation baffles before ceiling drywall is installed.
Image
Spray foam insulation air-seals and insulates the floor above the garage; the joist will be filled with fibrous insulation in this flash-and-batt approach.
Image
Spray foam insulation used for raised ceiling duct chase
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
Image
The original corner seam is air-sealed with caulk, then rigid foam is installed on the existing garage ceiling and walls, and finally covered with drywall.
Image
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 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
Wrong - Batt insulation does not provide complete coverage across the attic floor so ceiling joists are exposed resulting in thermal bridging.
Image
Image
Wrong - IR image shows a lack of air-sealing and insulation around a ceiling light fixture.
Image
Image
Image
Wrong - When ceiling joists over a garage run perpendicular to the adjoining wall, the joist bays must be blocked and sealed to prevent garage fumes from entering the living space
Image
Wrong – Insulation is in direct contact with this non-insulation contact (IC)-rated recessed light fixture
