The Seattle area’s unique climate—marked by cool, damp winters and mild summers—demands windows that offer superior insulation and energy efficiency. Upgrading to energy-efficient windows not only enhances indoor comfort but also leads to significant energy savings. In fact, homeowners can save between $125 to $340 annually by replacing single-pane windows with ENERGY STAR-certified models .
Key Features of Energy-Efficient Windows
When selecting windows for energy efficiency, consider the following features:
1. Multiple Panes with Gas Fills
Double or triple-pane windows filled with inert gases like argon or krypton provide excellent insulation. These gases reduce heat transfer, keeping your home warmer in winter and cooler in summer .
2. Low-E Glass Coatings
Low-emissivity (Low-E) coatings reflect infrared light, maintaining indoor temperatures and protecting furnishings from UV damage. Soft coat Low-E is particularly effective in Seattle’s climate .
3. Energy-Efficient Frames
Vinyl and fiberglass frames offer superior thermal resistance compared to traditional aluminum frames. Vinyl frames, in particular, are cost-effective and require minimal maintenance .
4. Optimal U-Factor and SHGC Ratings
For Seattle’s climate, look for windows with a U-factor of 0.30 or lower and a Solar Heat Gain Coefficient (SHGC) between 0.30 and 0.50. These ratings ensure effective insulation and appropriate solar heat gain .
Top Window Styles for Energy Efficiency
Certain window styles inherently offer better energy performance:
- Casement Windows: Hinged at the side, these windows seal tightly when closed, reducing air leakage.
- Awning Windows: Hinged at the top, they provide excellent ventilation while shielding against rain.
- Slider Windows: These horizontally sliding windows are known for their energy efficiency and ease of use .
Financial Incentives for Seattle Homeowners
Upgrading to energy-efficient windows can qualify you for various rebates and incentives:
- Puget Sound Energy (PSE) Rebates: Receive up to $200 per window, with a maximum of $2,000, for installing qualifying energy-efficient windows .
- Federal Tax Credits: Claim up to $200 in federal tax credits for ENERGY STAR-certified window installations .
