High-Performance™ Low-E4® Glass: The Ideal Glass Packages

Glazing, or the glass portion of the window, is the most important part of every window. The right glass package can dramatically improve indoor comfort and help you save on your energy costs in Nashville. This is why all Renewal by Andersen® replacement doors and windows come equipped with High-Performance™ Low-E4® glass. Here’s a closer look at these glass packages.

The Ideal Window Glass

Glass naturally conducts heat, which makes traditional, single-pane window glass problematic as it could allow heat to easily pass through, a phenomenon known as heat transference. During cold days, this would cause indoor heat to seep out while the reverse happens during hot days. The indoor cooling and heating systems would then use up more power to make up for the temperature difference, leading to higher monthly energy costs.

A double-pane glass solves this problem, thanks to the space between the two glass panes. Eliminating contact between interior and exterior surfaces dramatically reduces heat conduction and helps reduce your energy consumption. Unwanted ultraviolet (UV) and infrared rays, the latter being the source of heat from sunlight, are also blocked, thanks to spectrally selective low-emissivity (Low-E) coatings.

Renewal by Andersen® Glass Packages

Our High-Performance Low-E4 glass, which comes standard on all Renewal by Andersen window replacement units in Nashville, have all the aforementioned features.
