Summer Meeting Underway in Toronto
The Insulating Glass Manufacturers Alliance (IGMA) Summer Meeting
got underway yesterday with an early morning meeting of the certification
and education committees. Attendees gathered at 8 a.m. for a two-hour
meeting that looked at several issues, beginning with the addition
of the certification aspect to the education committee, both in
name and scope.
The group decided to incorporate certification into the education
committee, according to IGMA executive director Margaret Webb, because
it would be beneficial to have documented IGMA stances on the issues
The first part of the committee meeting was spent defining the objective
and goals of the committee in light of the addition. The committee
then turned its attention to the IGMA educational program. The "Preventing
Insulating Glass Failures" educational seminar is scheduled
to be presented at GlassBuild America in September, at Win-door
in Toronto in November and again in Tampa, Fla., in December.
Following the update on the IG failure seminar the committee looked
at planning of the next seminar IGMA expects to offer--a quality
procedure course. In discussing the potential seminar, the educational
committee worked on establishing the goals and objectives of the
course and moving forward with planning to bring it closer to becoming
reality. Committee members discussed what the most important elements
of the course should be and the language that would be needed to
clearly and adequately address the objectives and goals within the
program. A task group was formed that will hold conference calls
to facilitate further refinement of the course content and present
a proposal of the course curriculum at the next IGMA meeting in
The committee also discussed specific certification needs. Members
reviewed a report from the gas-fill working group, and discussed
that group's recommendations regarding how much gas fill would be
mandated for both initial and final fill for a company seeking durability
"What we're talking about is workmanship," said Webb.
"This is the test method. We're testing a manufacturer's ability
to make a good seal."
A consensus was reached to stress that the 90-80 percent requirements
being discussed were merely testing requirements as proof that an
IG system could retain gas fill to a given degree, and not a reflection
of the percentages of fill a manufacturer is expected to use in
the final product.
Before adjourning, the committee reviewed the guidelines governing
the testing of double- versus triple-glazed units, agreeing to stay
with the current IGMA guideline that all triple-glazed units must
be tested, and double-glazed units of like construction from the
same manufacturer qualify without separate testing.
After lunch, the technical working groups gathered, starting with
the glazing guidelines work group. The group reviewed amendments
to the guidelines regarding the use of thermo-plastics and the compatibility
thereof with sealants.
Afterward, the group moved on to new business, which led to a debate
about whether capillary tubes should be sealed and, if so, how.
"I'm all for an industry position. I think we're all better
off [with one industry position] than with many different positions,"
said Rick Wright of Oldcastle Glass.
A small working group was formed to draft a proposal of the appropriate
language for an industry consensus on the sealing of capillary tubes,
to be presented at a later date.
Up next was the gas permeability working group, which discussed
Phase 2 of the gas permeability project.
"Phase 1 is essentially done," said Bruce Virnelson of
PRC DeSoto International, the group's chairperson.
Next, the thermal stress working group met. After some discussion
regarding the "dos and don'ts" guidelines, the group took
a look at the IGMA thermal stress field service inspection record
and made a recommendation for changes to the language therein.
The byproduct was fine-tuning the one page document that works similarly
to a checklist and allows glaziers in the field to report breakage.
The data will be collected by IGMA for review, with hopes of determining
the cause of some of the breakage and the more common types of breakage.
Wrapping up the first day of meetings was the visual quality working
group, chaired by Joe Hayden of Pella Corp. Most of the meeting
centered around the definitions of industry language created by
a task group, which were presented for review and were subjected
to several changes. The next topic of conversation was the conformance
requirements; adhesive residue, desiccant dusting, dirt/debris,
fingerprints, fogging and suction/vacuum cup marks, all as defined
by the group in the previous discussion, are not allowed.
Lastly, the group reviewed the environment and parameters that must
be met when conducting inspection and were shown photos of visual
obstruction that have been added to the appendix to help illustrate
Task group meetings and technical presentations continue today;
the IGMA Summer Meeting runs through Tuesday, August 1.
