The Insulating Glass Manufacturers Alliance (IGMA) is holding its second IG Fabricator’s Workshop this week at the Intertek facility in St. Paul, Minn. It started Tuesday and runs through Thursday.

Participants of IGMA's IG Workshop prepare for Wednesday's hands-on training.

Tuesday afternoon, participants heard a series of presentations covering basic insulating glass (IG) knowledge, adhesion and desiccants, as well as optimum air spaces, gas filling, cutting, washing and more.

Wednesday, all that talk was put into action, as attendees were divided into groups for hands-on experience at six stations. These include: frost point; volatile fog; gas filling and measurement; sealant adhesion butterfly test; sealant mix test/desiccant testing; and glass cutting and washing.

“We give them the science, physics and theory on the first day, and on the second day, we physically do it,” says Bill Briese of GED Solutions. Briese is IGMA’s certification and education committee chair and hosts the glass washing and cutting section of the workshop.

Thursday, the event will conclude with a discussion on IG unit design. It will cover component compatibility, third-party certification and testing, industry standards, vendor qualification and failure analysis. The final hands-on session will be a tour and demonstration of the lab’s environmental test chambers and equipment.

Briese says the first workshop, which was held earlier this year at Intertek in Plano, Texas, was a big success, and the board later discussed what went well and what could be improved for future workshops. Some adjustments and additions were made for the second workshop.

“I think the biggest differences from the first workshop to this one are the inclusion of more spacer types and technologies,” says Briese. A segment on desiccants, for example, was added. “We brought in additional experts and just tried to make it even more well-rounded, so we could accommodate the attendees’ diverse methods of fabrications and components used.”

Most attendees are from glass fabrication companies and were divided into groups of three for the hands-on portion. “We want to keep it small enough that every attendee has an opportunity to get hands-on experience,” says Briese.
