The Technology That Makes Windows Energy-Efficient

Today’s technology has allowed our window company in Orange County, CA, to provide replacement windows that not only add functionality, but also make homes cozier.


Renewal by Andersen® of Orange County offers high-quality windows that come with insulating components, such as multiple layers of glass and high-performance frames.

Let us discuss the technology behind our energy-efficient windows.


This refers to the number of layers, various coatings, and other glass surface treatments that can improve a window’s energy efficiency. We offer dual-pane windows that maximize the space between the panes to ensure optimal energy efficiency similar to Orange County vinyl windows. It also comes with High-Performance™ Low-E4® glass, which can reduce the amount of heat that enters and leaves your home.

Low-Conductance Spacers and Gas Fills

Insulated Glass Units (IGU) feature an array of layers that contributes to their energy-saving properties. They are filled with inert gas like argon, which can improve the thermal performance of the IGUs. They also feature low-conductance spacers that can affect the space between the layers for an energy-efficient window.

Our windows are argon-filled and come with warm edge spacers made of stainless steel, which adds to their energy efficiency. Unlike other materials, our spacers offer a strong resistance to heat. This stabilizes our windows’ glass, while keeping it well-insulated.

Frame Material

Windows come in a wide range of frames. There are metal and non-metal frames, such as wood and vinyl. Our windows come with Fibrex® frame composite made from reclaimed wood and polyvinyl chloride (PVC) from the Andersen® Corporation factories. This gives it the classic beauty of wood, twice the strength, and low-maintenance features of vinyl. This means that our windows are resistant to rotting, fading, and blistering, assuring you of lasting performance.
