Triple-Glazed vs. Dual-Glazed Glass Option

Surber's Triple-Glazed Dual Titanium Low-E Glass, Krypton Gas	Standard Dual-Glazed Sputter Coated Low-E Glass, Argon Gas

The figure above illustrates the performance of Surber’s Magnum with a very low heat loss rate (low U-factor). In this case there are three glazing layers and two Low-E coatings, 3/8" krypton gas and 3/8" krypton gas fill between glazing, and Dura-Lite Spacer. With this window, both Low-E coatings are spectrally selective in order to minimize solar heat gain. This window is best suited for climates with both significant heating and cooling loads.

R-Value Vs U-Factor. What is more important?

R-Value stands for thermal resistance, and is typically measured in the center of glass only. R-Value does not measure the windows unit’s overall efficiency. U-factor is more important factor when evaluating energy efficiency. According to the US Dept. of Energy, Lawrence Berkley Labs- You shouldn’t consider a window with a U-Factor over .22.

Please notice that the standard dual pane windows with Low E and Argon gas do not meet the recommended U-Factor of .22 suggested by the US Dept. of Energy. While, Surber’s Magnum series windows out performs the recommended guide lines of US Dept. of Energy.

The Magnum Series of Windows from Surber's Windows and Doors is also available in a wide variety of glazing and screen mesh choices. With available woodgrain interiors, painted and custom painted exteriors, the choices of options are amazing!

SunClean™ Self-Cleaning Windows
Glass Option

View the SunClean™ Video

SunClean™ self-cleaning glass is a glass product with photocatalytic and hydrophilic properties that combine to result in windows that are easier to clean. The durable, transparent coating on SunClean™ self-cleaning glass is applied to hot glass during the formation process making it an integral part of the outer glass surface.

The photocatalytic properties of the glass coating are energized by UV rays to help slowly break down and loosen organic dirt.

The hydrophilic properties cause water to sheet evenly over the glass surface instead of beading. This sheeting action helps to flush the surface clean and to accelerate drying, leaving the glass with minimal spotting and streaking.

SunClean™ glass is available to makers of investment grade, vinyl replacement windows serving the new construction and remodeling market. SunClean™ glass is the most exciting new glass technology available to consumers.
