Working Groups Stay Busy During IGMA Annual Meeting
June 22, 2009
The Insulating Glass Manufacturers Alliance (IGMA) is working to
reduce its environmental footprint. During its Summer Technical
Meetings, which took place last week at the Hyatt Regency Montreal
in Quebec, the event was paperless as all of the meeting information,
including agendas, minutes, technical presentations, IGMA policies
and working documents for the groups and committees, was provided
to attendees on USB drives.
"We received extremely positive feedback on doing this so
we will definitely be repeating it," says Margaret Webb, IGMA
executive director. "We provided electricity to the groups
meeting as well as to the observers. The agendas and minutes were
posted to the IGMA website for the attendees to download in advance
and we did notify everyone that we would not be providing printed
materials. All in all this was an extremely successful, efficient
and effective way for the groups to have access to the documents.
I also ensured that everyone could see what was being posted to
the screen when we were working on document edits."
And there were a number of documents that were reviewed and worked
on last week by various committees and working groups.
During the Certification and Education Committee meeting members
reviewed the PowerPoint presentation for TM-4000, an introductory
overview on how to use the manual and implement a quality control
program for a manufacturer's specific requirements. Each section
is addressed with a minimum of four slides and each section includes
its purpose, key considerations for the element, sample work instructions
to provide guidance and sample forms to indicate the information
that should be captured. The presentation will now be balloted to
Activities of the Glazing Guidelines Working Group focused on the
current activities of the joint IGMA-GANA Task Group that is working
to develop manufacturing guidelines for the use of capillary tubes.
Key design considerations have been developed and the task group
is now working on language for each of the items included in the
During the Gas Permeability Working Group CAN-BEST presented the
design for the new test cell and test sample specification for Phase
2 -Evaluation of the Gas Permeability of Edge Seal Assemblies. Over
the next two weeks, CAN-BEST will work on validating the effectiveness
and the repeatability of the cell to measure samples at the sensitivity
required. The working group approved the work to date and will meet
by conference call and webinar to monitor the remainder of stage
one. Once the test cell design has been validated and approved,
the project will proceed to stage two, which is the actual testing
The Thermal Stress Working Group reviewed and finalized a list
of conditions that may or may not contribute to thermal stress.
Examples include solar absorption, shading conditions, frame color,
as well as many others. Volunteers were selected to write the text
for each condition and to identify the single condition for the
potential of low, medium or high thermal stress. The group also
will develop guidelines for a combination of conditions once the
information has been approved for individual ones.
A working group focusing on Design Considerations for Multiple
Airspace IGUs met for the first time and will work on developing
a technical report addressing issues such as thermal stress, gas
content, wind load, stresses on seal system, coatings, fabrication
techniques, altitude limits, glazing considerations (e.g. misalignment),
non structural intermediate layers (e.g. suspended coated film),
glass thickness (asymmetric constructions - glass and airspace),
structural glazing applications, exterior condensation and optical
considerations that may have special considerations for triple,
quad and greater glazed IGUs.
The Technical Services Committee was also busy with a number of
projects. Some of the group's activities included:
- Reviewing the status of code changes in Canada and the United
- Reviewing the new requirements for the ENERGY STAR programs
in Canada and the United States;
- Approving funding for the ASTM Thermal Stress project and the
AAMA Sloped Glazing document revision;
- Approving participation in a cross organization publication
resource library; and
- Reviewing the status of the TM-4000-02 (07) document revision
as well as the current status of various working group projects.
IGMA's next meeting will be its 2010 Annual Conference that will
take place during the Glass Association of North America's Glass
Week, March 24 - 27, in Las Vegas.
