and IGCC Move Closer to a Harmonized Approach to North American
At the meeting of the Insulating Glass Certification Council (IGCC),
held August 21-23, 2007 in Minneapolis, the Insulating Glass Manufacturers
Association (IGMA) and IGCC Certification Programs made significant
progress in streamlining and standardizing the certification program
for North American for the insulating glass (IG) industry. The associations
have been working to harmonize the two programs since Fall 2004.
Both programs have developed and implemented a Gas Content Initial
and After Weathering (GCIA). The guidelines for certification of
triple glazed units and test specimens were standardized between
the two programs when IGCC adopted the IGMA Insulating Glass Manufacturing
Quality Procedures (TM-4000-02) as the minimum requirement for the
program's quality assurance program. The quality procedures requirement
will be phased in over approximately the next 18 months.
"Both IGMA and IGCC have worked diligently on harmonizing
and streamlining the two programs," says Margaret Webb, executive
director of IGMA. "Each group has adopted the requirements
from the two programs which clearly represent the best approach
to providing the construction industry with the assurance that when
they specify units certified to these programs there are no insulating
glass units that have undergone a more rigorous threshold. We have
already standardized our short and mid-range targets and are well
underway to having one standardized approach for the manufacturing
According to John Kent, administrative manager for IGCC, "the
IG certification harmonization effort between IGMA andIGCC has afforded
an opportunity for each organization to take a hard look at best
practices, adopt guidelines and requirements which make sense for
the markets served, yet has still allowed each organization to maintain
its identity and oversight of their respective programs. Both programs
are better off for this effort and will add value to both the IG
fabricator and public interest user specifier segments of the market."
Webb says that IGMA does not currently have an estimate on when
the harmonization process will be complete, but the two groups are
working closely on the few remaining items. The next step for the
groups is to draft a list of "outstanding items" that
will be presented for consideration at the next IGCC meeting in
The next IGMA meeting will be held January 28-February 1, 2008
at the Sundial Beach Resort in Sanibel Island, Fla.
