We start out with just enough "science" to get you into the groove, then its on to applications: why they work, how to do it, and case history examples. A course manual is included for download with your enrollment. The course is divided into the following sections:
- Thermography Basics
- Moisture Investigations
- HVAC Investigations
- Insulation Investigations
- Air Leakage Investigations
- Electrical Investigations
- Structural Investigations
Details:
- Estimated Length: 2 hour(s) and 40 minute(s)
- Due: 6 month(s) from enrollment date.
- Access: 7 month(s) from enrollment date.
