Thermal Imaging in Building Audits: What Infrared Thermography Reveals About Windows

## Scientific Infrared Thermography in Fenestration Infrared thermography utilizes thermal imaging sensors to detect electromagnetic radiation in the long-wave infrared spectrum (8–14 μm). Converting radiant surface temperatures into high-contrast color palettes reveals thermal defects invisible to the naked eye. ### Common Defects Exposed by Thermal Scans: 1. **Uninsulated Shim Gaps:** Dark purple/blue voids around the frame perimeter indicating installers skipped low-expansion foam insulation. 2. **Failed Double-Pane Seals:** Temperature gradients across the glass center showing lost argon gas fill. 3. **Corner Sash Warping:** Infrared plumes escaping at lower meeting rails showing failed weatherstripping compression. Thermal imaging can help identify possible air-leakage or insulation issues around a window perimeter. An independent contractor determines which inspections are appropriate for the project.
