North Carolina's hot summers make energy-efficient windows a smart investment. Here's what you need to know about window upgrades.
Key Features of Energy-Efficient Windows
- Double or triple glazing – Multiple panes create insulating air pockets
- Low-E coatings – Microscopic layers reflect heat while letting light in
- Gas fills – Argon or krypton gas between panes improves insulation
- Quality frames – Vinyl, fiberglass, or wood-clad frames reduce heat transfer
- Proper seals – Weatherstripping prevents air leakage
Energy Savings Calculator
While upfront costs are higher, energy-efficient windows typically pay for themselves within 10-15 years through reduced cooling costs. Some homeowners see savings of 10-25% on energy bills.
Signs You Need Window Replacement
- Condensation between glass panes
- Drafts near windows
- Difficulty opening or closing
- Visible damage or decay
