Choosing the right architectural glass is crucial to a successful project. For more informed decisions in the evaluation, selection and specification of architectural glass, Vitro Architectural Glass (formerly PPG glass) recommends becoming familiar with the properties and benefits of the four most common glass types: low-e coated glass, clear glass, low-iron glass and tinted glass.
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 Transmittance, or Tdw-ISO, is considered the most accurate criterion for assessing potential fading damage.
Glass fabrication is an important part of glass specification. There are several basic types of fabricated glass, which all offer unique pros and cons. Types of glass fabrication include insulating glass units, laminated glass, opacified glass, decorative glass and more.
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 reflected off of glass, all of which factor into the glass' energy efficiency.
When designing with large expanses of glass, it is critical to know when the glass may need to be heat-treated for durability and/or safety. The type of processing required—heat strengthening or tempering—depends on the specific application.
Review the Slide Share for valuable information about key glass performance terms. The slides provide an overview on common terminology used in the glass industry, including: Visible Light Transmittance (VLT), Solar Heat Gain Coefficient (SHGC), Light-to-Solar Gain Ratio (LSG) and U-Value, both winter and summer.

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.
