Dennis K. Johnson

The Insulating Glass Certification Council (IGCC) recently completed its 2019 annual meeting in Tampa, Fla. In recognition of his many years of dedicated service to the organization, public interest board member Dennis Johnson of Raths, Raths & Johnson Inc. in Willowbrook, Ill., was elected IGCC president, according to the organization.

Johnson is a veteran industry expert with a more than 45-year career as a technical leader in investigation, repair design and performance testing of exterior wall and fenestration systems, and glazing materials.

“Dennis’s dedication to the principles and initiatives of IGCC have been significant over the years. He has a particular ability to apply his keen technical background to the discussions of the organizations while always keeping the IGCC mission of assurance to the public of product quality and performance forefront,” says John Kent, IGCC administrative manager.

The meeting agenda included numerous initiatives such as:

Rapid Assessment Chamber (RAC): IGCC renewed support of the RAC effort to develop a test method that can evaluate insulating glass unit performance in a shorter time period than the current ASTM E2190 standard. Further data is expected in the fall of 2019 with a correlation study anticipated in early 2020.

ASTM Standard Revisions: With the recent release of the 2019 versions of ASTM E2188, E2189 and E2190, IGCC reviewed the implementation of these standards revisions as they apply to the IGCC approved testing laboratories and IGCC/IGMA certification program (specific direction to be provided to all IGCC/IGMA participants).

North American Harmonization: There remains interest in growing the insulating glass certification process for both the U.S. and Canada closer together. Differences in the IGCC/IGMA ASTM E2190 program and the IGMAC CAN/CGSB 12.8 programs were compared and best practices identified. IGCC approved moving forward with this effort through continued dialogue with IGMA/IGMAC.

New Product Codes: Final approval was established for insulating glass component codes. More than just a way to identify components, these codes serve as the definition of generic equivalency between products and affect the required insulating glass testing. This project has been a thorny issue for many years as it will influence alternate sources of supply for fabricators. However, the guidance established should put to rest discrepancies between how this matter was handled in the U.S. and Canada, furthering North American harmonization, according to the organization.
