Install an air barrier on the exterior of attic knee wall insulation.

Image

Install insulation under platforms constructed in the attic for storage or equipment.

Image

Right – The backing on this knee wall was air sealed prior to insulation.

Image

Right – HVAC platform installed to allow for proper insulation depth

Image

Right – Insulation installed to correct depth and will be aligned with air barrier

Image

The rim band connecting the insulated precast concrete basement walls to the floor joists above is spray foamed to provide air-sealing and insulation in this hard-to-seal juncture.

Image

This refrigerant line was correctly insulated and wrapped with a weather-resistant covering but the tape covering is losing its adhesion due to exposure; pipe insulation should be checked annually for wear.

Image

Insulated concrete forms (ICF) provide an insulated below-grade foundation wall; the floor is connected to the ICF wall with joist hangers and ledger bolted into the concrete core of the ICF

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
