Replacement options (long-term fix)
- IGU (Insulated Glass Unit) replacement: Replace only the glass unit while retaining the existing frame—cost-effective if frames are in good shape.
- Full window replacement: Replace sash/frame and glass—best when frames, hardware, or thermal breaks are compromised or for upgrading to more efficient glazing (low-E, gas fills).
- Upgrades to consider: Low-E coatings, argon/krypton gas fill, improved spacers (warm-edge spacers), and laminated glass for safety/noise reduction.

Fix or Replace? The Exclusive Decision Guide
| Condition | Best Action | |-----------|--------------| | Single failed IGU, window under 10 years old | Replace just the glass unit | | Multiple failed seals, windows 15+ years old | Replace entire windows | | Foggy but frame rotting or hard to operate | Full window replacement | | Historic home with custom wood sashes | IGU replacement + sash rebuild | IGU (Insulated Glass Unit) replacement: Replace only the
Visible Distortion: Without the internal gas pressure, panes may bend slightly, causing warped reflections.
- Protect the Exterior: Ensure your window overhangs (eaves) are intact. Direct rain and UV exposure accelerate sealant decay.
- Mind the Pressure: Do not drill into window frames for decorations or sensors. This breaks the "thermal envelope."
- Caulking: Inspect the exterior caulking annually. If the frame shifts due to structural settling, the glass twists. Good caulking acts as a shock absorber.
Technical Overview: Broken Window Seal Failures A broken window seal in an Insulated Glass Unit (IGU) occurs when the airtight barrier between glass panes fails, allowing the insulating gas (typically argon or krypton) to escape and moisture-laden air to enter. This failure compromises the window’s thermal performance and aesthetics. 1. Primary Causes of Seal Failure Thermal Stress
The Seal: A flexible perimeter that holds the glass together and blocks external air.
