IGMA, an ISO 9001:2008 accredited organization and registered Standards De-
velopment Organization (SDO) was formed on October 2, 2000 as a result of a
merger between the Insulating Glass Manufacturers Association of Canada
(IGMAC) and the Sealed Insulating Glass Manufacturers Association (SIGMA).
IGMA represents certified insulating glass manufacturers, their suppliers, associ-
ates and customers both in the residential and commercial markets across North
America and around the world.
IGMA members are very smart people working together and closely with other
standards development groups, governments and other organizations to estab-
lish North American and international industry standards.
IGMA focuses our financial and staff resources in two major areas of importance
to the industry: Certification and Technical Practices.
Since October 2000, IGMA has published 5 major technical manuals addressing
pre and post fabrication subject matters in a straight forward, practical ap-
proach. In addition, we developed a product certification program for the
North American markets, completed 3 research projects with a fourth currently
underway.
Technical activities
Standards development, lead-
ing edge research, harmoniza-
tion of standards, voluntary
guidelines, technical manuals,
reports and bulletins, best prac-
tices and online educational
programs.
Our Technical Presentation Li-
brary has over 75 PowerPoint
presentation covering compo-
nents, compatibility, manufac-
turing, new technologies and
many, many other topics of in-
terest to the industry.

“I found the Preventing IG
Failures seminar to be helpful &
educational. I would like to see
the continuation of this type of
service to the manufacturing field.
As a manufacturer I would attend
more of these seminars.”
The Technical Services Committee
defines what IGMA is all about.

Certification & Education
The Certification & Education
Committee is responsible for all
IGMA educational programs
including Preventing IG Fail-
ures.
The group has developed a
PowerPoint presentation which
will provide an overview on
why and how to implement
and maintain a quality control
system. This presentation is
based on the technical man-
ual TM‐4000—IG Manufactur-
ing Quality Procedures. And is
close to completion. Sections
on Training, Process Control
and Field Service will be sub-
mitted and reviewed at the
September 2010 technical
meetings.
The document revision of TM‐
4000‐02(07) which will result in
two separate documents is
under the responsibility of the
Technical Services Committee
and is an online task group.
At the March 2010 meeting it
was decided to reinstate the
IGMAC Certification Proce-
Technical Services Committee
Participation on the Technical Services
Committee is by invitation from the
IGMA Board of Directors and all commit-
tee members must have technical ex-
pertise in their designation position.
The TSC is the standards development
arm of IGMA and has responsibility for all
Task Groups, technical publications and
technical support to the IG certification
programs.
Glazing Guidelines
Unlike other task groups, the
Glazing Guidelines work group
is a permanent task group
under the IGMA technical
structure.
This group is responsible for
developing and maintaining
best practices in glazing for
both residential and commer-
cial products.
Current activities include a
review of the Setting Block
height and placement for
residential products especially
when the window includes a
triple-glazed IGU.
The group is developing guide-
lines for use of capillary tubes
and will include manufactur-
ing considerations.
TM-3000-90(04), North America
Glazing Guidelines for Sealed
dures Committee so that pro-
gram participants are involved
in developing the program
requirements. This committee
will meet online.
Matters relating to equiva-
lency and waivers will be re-
viewed by the IGMA Technical
Policy Committee.
The Committee includes representa-
tion from all industry sectors; manufac-
turers, equipment manufacturers,
component suppliers, testing, inspec-
tion, consulting and government and is
equally balanced with representation
from Canada and the U.S.
Based on feedback from the general
membership, this committee is respon-
sible for setting IGMA’s code positions.
Insulating Glass Units for Com-
mercial and Residential Use is
included in the IGMA techni-
cal binder. Discounts are
available to members for bulk
orders.

IGMA is populated with very smart people who work for companies
that care about the insulating glass industry and support their em-
ployees participation in IGMA. For the benefit of the industry, these
individuals come together to pool their individual areas of expertise
and years of experience to develop technical documents and briefs,
explore, research and validate new technologies, provide education
programs for quality control and fabrication processes for the manu-
facturers.
Support comes in many forms, all of which are important. IGMA would not be the organi-
zation it is today without out volunteers.
Some companies contribute sponsorship funds over and above the annual membership
fee and costs to attend the meetings. We have included each of these sponsors in the
current newsletter as our way of acknowledging the contribution and saying thanks to
each sponsor.
Sponsorship dollars underwrite the cost of the meetings which lowers the registration fee to
a more manageable amount. Without these funds, the cost of the meetings would in-
crease by 40%. We encourage all members to personally thank our sponsors if the opportu-
nity presents itself.

Thermal Stress
This group is developing guide-
lines for thermal stress consid-
eration for annealed insulating
glass units which will include a
number of conditions classified
as low, medium and high risk.
Conditions that have been
identified are glass type, solar
absorption and radiation, heat
traps (outdoor field condi-
tions—outdoor shading, blind
pockets and glazing stop
color), heat traps for indoor
conditions (position of HVAC,
Development of a Test Protocol

through Insulating Glass
Units
Currently in Stage 1, Phase 2 of
the research project to de-
velop a standardized test
specification for gas perme-
ability, the test cell has been
re‐designed to permit sam-
pling of 5 IGU samples at a
interior shading devices),
spandrel glazing, framing sys-
tem type (wood aluminum /
steel, concrete), # of glazing
lites (doubles, triples, quads),
elevation, on site storage con-
ditions, post installation films,
altitude, and design winter
temperature. Once the table
grid has been completed for
these conditions, a second
grid will be developed for
combination conditions.
The introductory section has
time and significantly reduce
the time to obtain data results.
The new setup will also ac-
commodate Phase 3, which
will mechanically stress the
units to simulate field condi-
tions. Prior to sampling, the
system is purged with medical
Grade Helium using a helium
ionization detector. Current
issue is getting a clean base-
been written and includes a
detailed definition and de-
scription of thermal stress in-
cluding why it happens and
how to identify it. This docu-
ment will compliment the
Glass Breakage webinar under
the Preventing IG Failures edu-
cation program.
Design Considerations Multiple Airspace IGU’s
As Energy Star requirements
become more and more strin-
gent, triple and quad glazed
insulating glass units will be-
come the norm in many of the
climatic zones.
This task group convened for
the first time in 2009 and work
is well underway on identifying
conditions that should be ad-
dressed when designing and
fabricating triple and quad
glazed insulating glass units.

A format for the document
has been approved which will
be similar to the visual quality
guidelines released in 2009.
Text has been drafted for gas
content, coatings and exterior
condensation. Outstanding
topics of thermal stress, wind
load, stresses on seal system,
fabrication techniques, alti-
tude limits, glazing considera-
tions (e.g. Misalignment), non
structural intermediate layers
(e.g. suspended coated film),
glass thickness (asymmetric
constructions – glass and air-
space), and structural glazing
applications have been as-
signed to task group members.

been delayed by 4 months. At
the conclusion of this phase,
the IGMA Research Fund will
be depleted and IGMA will be
soliciting outside funding.
Every meeting includes technical presentations
on new technologies, fabrication
techniques and a host of other
topics of interest to the IG industry
