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 the glass due to the difference between indoor and outdoor temperatures.
Clear glass is extremely common and is popular in a variety of architectural design applications. However, when specifying glass to achieve a truly transparent aesthetic, design professionals know that clear glass isn’t completely clear—it has a distinct green hue when viewed under light.
Imagination and creativity are critical skills that enable architects to create beautiful, vibrant and sustainable buildings. However, one aspect of successful projects that often goes under the radar is the glass specification. From project conception to completion, specifications provide a necessary “check and balance” to ensure that the proper products are being used and that current industry standards are being followed.
Achieving optimal performance of solar control low-e glass and passive low-e glass requires proper placement of low-e coatings on the glass surfaces of an insulating glass unit (IGU). Placement considerations vary depending on whether the glass is solar control low-e glass or passive low-e glass, and whether the IGU is double- or triple-glazed.

The first insulating glass units were developed in 1945 for the Pullman Car Company in Butler, PA.
A standard float tank can produce glass 24 hours/7 days a week for up to 15 years before it needs to be rebuilt.
