GANA Releases New Informational Bulletins
December 11, 2012

The Glass Association of North America (GANA) announced today that it has released two new Glass Informational Bulletins (GIB) in the past month, as well as an updated version of a previous GIB.

The first new GIB, titled Coastal Glazing and the Turtle Codes, discusses the coastal issue of turtle hatchlings mistakenly heading to the bright lights on shore instead of out to the ocean. The GIB walks through the Florida building codes on the issue and discusses the positive benefit tinted, low-E and reflective coated glass may have in solving the issue by meeting the turtle code requirement of visible light transmittance (VLT) of 45 percent or less in new construction.

The second new GIB, titled Physical and Mechanical Properties of Typical Soda Lime Float Glass, gives detailed technical information on the strength and other properties of this specific type of glass.

In addition to the two new GIBs, GANA has released an updated version of The Importance of Fabrication Prior to Heat-Treatment, a GIB it originally released in 2007. The GIB reinforces the difficulty in trying to fabricate heat-treated glass, thus making it prudent to fabricate prior to the heat-treating process.

The GIBs are available for purchase in the GANA Store for immediate download at a price of $10 each.

GANA members may log in and download the GIBs free at, while others in the industry can visit the GANA store at to purchase the GIBs and browse other GANA products, manuals and videos available for purchase.
