Energy Efficient Window

Up to 40 percent of heating energy can be lost during the winter with poor performing windows. They can also lose up to 50 percent of your home energy in the summer. It can get expensive to have a worn out or inefficient window.

The easiest way to compare is the NFRC label. The label means that the whole window has been test and not just part of the frame or the center. The U factor better indicates the performance of the window than the R-value. The lower the U-Factor the better the insulation is.

*35% more energy efficient in the winter and 41% during the summer, is compared to dual pane glass.

Low-E2 Glass

San Diego’s Best Window products are engineered with state-of-the art glass technology to give your home energy efficient performance. It all begins with premium, insulated glass separated by a “warm-edge” spacer systems to create optimum air space between panes. This sealant technology keeps the glass in place while allowing it to flex with hot and cold weather changes to help resist failure and stress cracks.

To provide advance thermal performance, this glass system also uses Low-E2 glass that has been formulated to reject heat and damaging rays. Low-E2 glass actually reduces window heat gain by 50% or more when it’s compared to traditional glass.

Low – E Glass + Argon Glass

Argon gas works like an insulating blanket between two panes in the glass to further improve thermal efficiency. Insulated glass unit using Low-E Glass with Argon Gas provides the best insulating value for your San Diego home. Only available with Low-E glass.

A bonus of our warm-edge insulated glass sealant system is it’s ability to create a single seal that provides retention or argon gas. This system assures you of thermal energy efficiency.

Climate Shield3

Low-E glass is coated with microscopic layer of silver that reflects solare energy while permitting light to pass through the glass, providing more comfort and lower energy cost.
