Description
In many buildings, air leakage is the single greatest source of heat loss through the building envelope. Air leakage areas can be difficult to find, but they’re usually inexpensive to fix. This lesson covers common areas of air leakage found in residential buildings. You’ll learn the following:
- Where to look for major leakage areas.
- How to correctly seal leakage areas.
- Techniques to measure the post-improvement effectiveness of air-sealing work.
