Air Barrier Inspection:

A building envelope performance verification or Air Barrier Inspection is a recently adopted amendment to the 2021 IECC building codes. The inspection requires a certified professional to view the air barrier prior to siding installation, to ensure that the house wrap and other items provide a continuous air barrier to a home, are installed properly, and that all air leaks are minimized where possible before the exterior is covered up. An air barrier inspection does not require you to use specific products or wraps, but it takes all of these products into account to ensure the building envelope is as tight as it can be.

The known list of areas that require this inspection are as follows:

• Larimer County

Air Barrier Inspections are visual inspections. The same techs who perform our Blower Door Tests perform our air barrier inspections so they are familiar with common air leaks through building envelopes. We will be looking at all penetrations through the envelope, and all known weak areas.

What is inspected during a Building Envelope Performance Inspection:

The following items are looked at for proper envelope sealing. These are taken directly from the IECC code – Table N1102.4.1.1

• Ceilings/Attics
• Walls
• Windows/Skylights/Doors
• Rim Joists
• Floors
• Basements/Crawl Spaces/Slab Foundations
• Shafts/Penetrations
• Narrow Cavities
• Garage
• Recessed Lighting
• Wiring/Plumbing/Other Obstructions
• Showers/Tubs
• Electrical or Phone Boxes
• HVAC Register Boots
• Concealed Sprinklers

Upon completion of an air barrier inspection, we will send you a letter of certification that a 3rd party inspector verified the insulation levels. We will also keep photos on hand for any future verification needed.
