Industry Provides More Education and Information
About Protective and Laminated Glass
April 9, 2010
Earlier this week a middle-school student in Hastings, Minn., entered
the school with a gun, breaking windows alongside locked classroom
doors in an attempt to gain access to classrooms. Now, the school
has put out bids for 33 impact-resistant interior windows to replace
the glass currently installed (CLICK

glass grows, groups within the Glass Association of North America
(GANA) are taking strides to make available information and education
about the use of and designing with protective glazing and laminated
glass. GANA's Protective Glazing Committee and its Laminating Division
met recently during Glass Week in Las Vegas where both groups tackled
a number of projects.
The Protective Glazing Committee has created a Protective Glazing
101 presentation that is currently being reviewed by the American
Institute of Architects. The script for the presentation is in draft
form and covers areas such as bullet- and bombblast-resistance,
"Presently, it is mostly focused on standards and test methods
and how to understand performance in these areas," explained
Valerie Block, chair of the committee.
The committee is also working with the Protective Glazing Council
International to jointly develop a Protective Glazing Manual.
The task group has one last section to finish and is reviewing edits.
Once the manual is approved the group expects that it will be published
sometimes this spring.
The group is also working on a draft of a glass informational bulletin
(GIB) on screening out ultraviolet radiation with laminated glass.
With edits reviewed during the meeting, the draft will now be sent
out for a final review before it is balloted.
The Laminating Division also has published three GIBs: Emergency
Egress, Hurricane Substitution Explanation and Laminated Glass Weight.
In addition, a 2009 version of the Laminated Glass Reference
Manual was also published last year.
Julie Schimmelpenningh of Solutia Inc. provided an update on ASTM
working group 22334, New Specification for Consumer Safety for
Glass Furniture. She explained that the group is focusing on
horizontal, non-uniformly supported applications, such as tabletops.
"The group is saying that all safety glass used in these applications
must meet ANSI Z97.1. They also do not want to have to label the
glass," said Schimmelpenningh.
A draft of the specification is currently being reviewed and Schimmelpenningh
said the intent is to publish it as a voluntary standard and not
move it on to CPSC.
Recognizing the importance of educating the industry on safety glazing
in furniture applications, the division formed a task group that
will write a GIB on glass in furniture.
Other future projects for the division include GIBs on laminated
glass in railing systems, laminated glass in adaptive glazing systems
and material compatibility with laminated glass.
