One way to air seal and insulate kneewalls – add insulation and a rigid air barrier along roof line of unconditioned attic space outside kneewall
Image
Raised ceiling duct chase installation technique
Image
Raised heel energy trusses extend past the exterior wall and are deeper at the wall allowing room for full insulation coverage over the top plate of the exterior walls.
Image
Retrofit an existing roof by installing rigid foam, new moisture and air control layers, new sheathing, and new cladding plus cavity insulation in the roof rafters to create an unvented attic
Image
Right - A technician applies a thin layer of closed-cell foam to air-seal an unvented attic assembly before filling the ceiling joists with batt or blown insulation.
Image
Image
Right - Baffles are installed in attic to keep blown insulation from blocking soffit vents and ventilation path
Image
Right - Blown insulation in existing attic provides even coverage completely filling the attic space to a depth that covers the ceiling joists.
Image
Right - Closed-cell spray foam covers the ceiling and joists to insulate and air-seal the ceiling deck.
Image
Right - Continuous wall sheathing and blocking has been installed to brace the raised heel trusses.
Image
Right - Open-cell polyurethane spray foam to R-28 on underside of roof turns new attic into conditioned space for HVAC.
Image
Image
Right - Raised-heel roof trusses allow more room at the eaves for attic insulation.
Image
Right - Spray foam insulates the attic eave between the attic floor and the SIP roof panel.
Image
Right - Spray foam insulation air-seals the ceiling-to-drywall seams at the wall top plate.
Image
Right - Spray foam insulation has been sprayed onto the underside of the sloped roof and the gable end wall to provide a sealed, insulated attic for housing the HVAC ducts
Image
Right - The attic access panel is insulated and weather stripped and a dam is built to hold back the blown attic floor insulation
Image
Right - The energy recovery ventilator ducts supply filtered outside air to multiple locations in the home and continuously exhaust stale air to provide clean, balanced ventilation.
Image
Right - The underside of the attic roof deck is insulated with open-cell spray foam to provide an insulated space for HVAC equipment.
Image
Right - The wall top plates are sealed with foam before installing insulation on the ceiling deck.
Image
Right - These attic knee walls are insulated with rigid foam and sealed with spray foam to form a continuous air barrier at the gable end of this cathedral ceiling.
Image
Right - These raised heel roof trusses provide 16 inches of space over the outer walls for full insulation coverage at the attic perimeter.
Image
Image
Right - This new sealed attic has 5.5 inches (R-20) of spray foam insulation along the underside of the roof deck providing a conditioned attic space for the heating and cooling ducts.
Image
Right – Attic access hatch has been properly insulated by attaching a fiberglass batt, gasketed, and opening has blocking
Image
Right – Attic access door has foam and rubber weatherstripping installed that remains in contact when closed.
Image
Image
Right – Blocking has been installed around the perimeter of this attic access to prevent insulation falling into the house
Image
Right – Closed-cell polyurethane foam is sprayed on the underside of the roof deck to provide structural connections and seal seams in the sheathing to increase wind resistance
Image
Image
Right – Insulation installed to correct depth and will be aligned with air barrier
Image
Image
Right – Open-cell spray foam is installed over closed-cell spray foam in this hybrid approach to achieve adequate attic ventilation while allowing some vapor permeability.
Image
Right – R-23 of blown fiberglass fills the walls and unvented vaulted attic cavities of this marine-climate home while an additional R-20 (4-inches) of graphite-enhanced expanded polystyrene is installed above the roof sheathing.
Image
Image
Right – Roof underlayment is fully adhered and roof deck seams are sealed so roof is resistant to high-wind events
