Energy Efficient

What Are Energy Efficient Windows?

Energy efficient windows are designed to minimize heat transfer between the interior and exterior of your home. They help maintain comfortable indoor temperatures year-round while reducing heating and cooling costs.

Key Performance Factors

U-Factor

The U-factor measures how well a window prevents heat from escaping. Lower numbers indicate better insulation. Energy efficient windows typically have U-factors of 0.30 or lower.

Low-E Coatings

Low-emissivity (low-E) coatings are thin, invisible layers applied to glass that reflect infrared light. They help keep heat inside during winter and outside during summer, improving comfort and reducing energy use.

Multiple Panes

Dual-pane and triple-pane windows trap insulating gas (such as argon or krypton) between the glass layers, significantly reducing heat transfer compared to single-pane windows.

Benefits for Bay Area Homes

In the San Francisco Bay Area, energy efficient windows help manage temperature swings, reduce reliance on HVAC systems, and lower utility bills. They also improve comfort by minimizing drafts and cold spots near windows.
