What Is Double Pane Glass?
Double pane windows — also called insulated glass units (IGUs) — consist of two panes of glass separated by a sealed spacer filled with air or argon gas.
This design provides several advantages for homes and businesses.
Benefits of Double Pane Windows
- ✅
Better insulation and energy efficiency
- ✅
Reduced outside noise
- ✅
Improved indoor comfort
- ✅
Lower heating and cooling costs

Less condensation on interior glass
Because Mukilteo sits near the coast, homeowners often experience temperature fluctuations and humidity, making insulated glass especially important.
However, when the seal fails, moisture can enter between the panes, causing foggy windows and reduced insulation performance.
Signs Your Double Pane Window Has Failed
Many homeowners in Mukilteo notice window problems months before realizing the seal has broken.
Common warning signs include:
1. Fog Between Glass Panes
Condensation trapped between panes is the most obvious indicator of seal failure.
2. Cloudy Windows That Won’t Clean
If a window looks hazy even after cleaning both sides, the moisture is trapped inside the glass unit.
3. Cold Drafts Near Windows
Failed insulated glass allows outside air to affect indoor temperature.
4. Higher Energy Bills
If your heating costs increase during winter, your windows may be losing insulation.
5. Cracked or Broken Glass
Impact damage often requires replacing the insulated glass unit.
6. Moisture or Water Inside the Window
Water droplets inside the window assembly indicate seal failure.
When these symptoms appear, replacing the insulated glass unit is usually the best solution instead of replacing the entire window.
