GANA Perspectives

Hard Work Pays Off
GIBs Supplement Library of Technical Resources
by Urmilla Jokhu-Sowell

The Glass Association of North America (GANA) is nearly halfway through its membership year and our volunteers have kept their noses to the grindstone to accomplish their technical goals. We have published a number of new Glass Informational Bulletins (GIB) to supplement the library of technical resources.

BEC Division
The Top 10 Items Commonly Missing from Fenestration System Shop Drawings

Shop drawings must document and detail all requirements of design parameters, material ordering, fabrication and erection. Failure to properly document these requirements can result in numerous errors and project delays. In order to provide a reminder of key elements of successful shop drawings, members of GANA’s Building Envelope Contractors Division developed a list of the top ten items commonly missing from fenestration systems shop drawings.

Safety Guidelines for Deglazing Structural Silicone

This GIB was written based on the personal experience of one who was injured in a deglazing process. Given the expected influx of new people into the glazing profession, the GIB should be used as an overview of how to approach the deglazing of glass without injury by those who are not familiar with a situation that always exists on projects utilizing glass.

Decorative Division
Recyclability of Architectural Glass Products

The need for recycling glass will not diminish with time and new ways in using recycling glass will appear. This document will provide a quick understanding of what is currently happening with glass recycling in North America.

Assessing the Durability of Decorative Glass

The durability of a decorative glass product is a complex characteristic. Durability must be considered in context, against what factors the product must be durable. This document offers a profile of a number of important durability properties.

Energy Division
White Paper:
LEED v4 - updated

The intent of this white paper is to address areas of the U.S. Green Building Council’s LEED® rating system that are relevant to the use of glass. 

Insulating Division
Guidelines for Use of Capillary Tubes

This joint document written by members of GANA and the Insulating Glass Manufacturers Alliance discusses considerations for capillary tubes and provides direction for proper design, application and advantages/disadvantages for their use in insulating glass.

Laminating Division
Marking and Labeling of Architectural Laminated Glass – updated

The purpose of this GIB is to provide guidance and clarity to the various permanent marks or manufacturer’s designations currently being applied and/or required for the laminated glass infill of a fenestration assembly.

Effects of Moistures, Solvents and Other Substances on Laminated Glazing Edges

This document provides information relative to the edge effects on laminated glass due to moisture, solvents, standing water, caulks, sealants, tapes, gaskets, setting blocks and glass cleaning solutions on laminated glazing edges.

Tempering Division

The Importance of Fabrication Prior to Heat-Treatment

Glass applications frequently require a variety of glass edge and/or surface fabrication. This GIB discusses fabrication processes that should occur prior to heat-treatment.

Recommended Applications for Heat-Treated Architectural Glass

Heat-treated glass is used in many of today’s architectural glazing applications where increased strength to resist glass breakage is desired. This GIB discusses types and uses of heat-treated glass applications.

Protective Glazing Committee
Security Glazing in Schools

With the topic of school violence frequenting the news, schools are increasingly seeking solutions to prioritize safety. This GIB outlines various types of security glazing, including forced-entry resistant laminating glazing; bullet-resistant laminated glazing; blast-resistant laminated glazing; and hurricane-resistant laminated glazing.
