In the quest for home energy efficiency, the role of windows cannot be overstated. They are crucial components influencing not only the aesthetics of your residence but also its comfort and energy usage. That is why you have to look specifically for energy-efficient windows. 

In this post, we discuss the key features that make windows energy-efficient.

Window Frames and Materials

The frame material contributes to the overall performance of a window. Composite frames, for instance, combine materials like wood with polymer plastics for improved thermal and moisture resistance. Fibrex® is a type of composite material that pairs the strength and durability of wood with the low-maintenance quality of vinyl.

Glazing and Glass Technology

Beyond frame materials, the glazing or glass used also affects an energy-efficient window’s performance. Double or triple glazing is typically applied, creating an insulated barrier between indoor and outdoor environments. Argon and krypton gas fills further enhance this insulation, helping to minimize heat transfer. Moreover, low-emissivity coatings are an innovative technology that reflects heat while allowing light to pass through. 

U-Factor and SHGC

The U-factor represents the effectiveness of a window’s insulation. It indicates the rate of heat transfer — a lower U-factor means a window is more conducive to maintaining a balanced indoor climate. This, paired with the solar heat gain coefficient (SHGC), helps determine the window’s ability to resist unwanted solar heat. The lower the SHGC, the better the window is at blocking incoming heat.

Weatherstripping

Although often overlooked, the quality and installation of weatherstripping can dramatically affect a window’s energy efficiency. A tight seal averts air leakage and drafts, which is vital for sustaining the desired indoor temperatures.

Professional window installation is a fundamental component of energy efficiency. With California Energy Consultant Service, you can rest assured that your windows will be installed properly. Call us at (916) 993-5000 or fill out our contact form to schedule an appointment.
