PPG Industries has posted a new video about specifying glass to prevent thermal stress breakage in the PPG Glass Education Center, a comprehensive website that helps architects, specifiers, students and construction industry professionals learn more about designing, specifying and building with glass.
The five-minute video features Paul DiCesare, PPG manager of architectural quality assurance, flat glass, discussing how to protect glass against thermal breaks, which result when the center of glass in a window unit heats and expands while the edge remains cool. The tutorial covers other variables that can factor into glass’s ability to resist cracks from thermal stress, including glass type, coating type, the surface location of the coating, outdoor and indoor shading patterns, heating vent location and framing systems.
Viewers also are directed to a free analysis tool at www.ppgideascapes.com that generates a calculation to help assess the risk of thermal stress for individual glass units according to their specified dimensions, coatings, location and related characteristics.
The PPG Glass Education Center is a growing library of glass technical information that serves as an objective, user-focused online resource for glass and building industry professionals. Content is updated regularly based on the most frequently asked questions PPG fields on its website, during sales calls and through its call center. The website currently hosts 12 videos, eight infographics and three slideshows.
