Do you have foggy windows?
Dual-pane windows can often be repaired by replacing the insulated glass unit (IGU) without replacing the entire window frame. This restores clarity, insulation, and energy efficiency when the seal has failed or condensation develops between the panes.
Dual-pane windows are made with two sheets of glass separated by a spacer and sealed airspace. This design improves insulation and helps regulate indoor temperatures.
When the seal around the glass fails, moisture can enter the space between panes, causing fogging or cloudiness that cannot be cleaned from either side.
The most common causes of dual-pane glass failure include:
- Seal deterioration over time
- Exposure to temperature changes
- Minor impact damage
- Manufacturing or installation defects
Once the seal fails, the insulating air or gas escapes and moisture becomes trapped between the panes.
In many cases, the window frame remains in good condition even when the glass has failed. Replacing only the insulated glass unit allows the window to function properly again without the cost or disruption of full window replacement.
For most homeowners, professional glass replacement ensures the dual-pane unit is accurately measured, ordered, and installed for long-term performance.
Single-pane windows contain only one layer of glass and are simpler to replace. Dual-pane windows require replacing the sealed unit to maintain insulation and clarity, but the frame can often stay in place.
