Compared to glass alone, the National Fenestration Rating Council (NFRC) performance ratings of window units typically vary in several ways that may not be immediately apparent. To understand why ...
One of the most important glass performance measures is U-value—also known as U-factor—which measures the insulating characteristics of the glass, or how much heat flow or heat loss occurs through ...
As one of the most popular and versatile building materials used today, low-e emissivity (low-e) glass coatings can enable exceptional energy efficiency and aesthetics. But how do they work?
For years, UV light transmittance used to be thought of as the measure of a glazing material's ability to protect furnishings from fading due to sunlight exposure. Now, ISO Damage Weighted ...
Understanding the solar energy spectrum is key to understanding glass coatings. Glass coatings affect the way the different parts of the solar spectrum are absorbed into, transmitted through or ...
While glass looks great aesthetically, it also has to meet high performance standards. An important part of performance relates to acoustics, whether it’s large, dramatic panels used for the exterior ...
Sometimes glass breaks in a building without any obvious cause. When this occurs, it could be due to glass edge damage or surface damage from handling and glazing that then weakens the glass during ...
There are three parts to the solar energy spectrum: infrared, visible and ultraviolet. Glass consequently responds to these three different types of light in three different ways: by reflecting, ...
