Module 5 - Openings and Penetrations examines good strategies and materials required to create a robust air barrier, specifically when dealing with places where vents, plumbing, openings and wires pierce through it.

In this module, you'll examine situations like:

• Window and door openings
• HVAC venting holes
• Chimneys and attic hatches
• Appliance venting holes
• Utility conduit penetrations and outlets

When you're ready, you can attempt the Openings & Penetrations quiz and move on to the next section in Air Barriers for Professionals.
