The Insulating Glass Manufacturers Alliance (IGMA) 2018 Winter Conference continued this week in Tucson, Ariz., with reports from the emerging technology and innovation committee.
Mike Hart with HUMAN gave a presentation about managing risk and opportunity.
He explained that risk is a potential for loss and opportunity is a potential for gain.
“Taking or not taking an opportunity then presents different levels of risk,” said Hart.
He outlined several methods for analyzing risk and opportunity regarding external opportunities, such as customer satisfaction, and internal risk, such as understanding the needs and expectations of stakeholders.
David Cooper of Guardian Industries reported that the vacuum insulating glazing (VIG) task group has sent out ballots for the first phase of a VIG durability standard. Manufacturers would submit test samples to be measured for R-factor within the first phase. The second phase would focus on thermal stability.
The insulating glass thermal stress task group’s Bill Lingnell, of Lingnell Consulting Services and IGMA technical director, reported that the committee is analyzing dynamic thermal stress.
“Max thermal stress conditions happen when you have a major temperature difference in 20 to 30 minute’s time. It’s not instantaneous. It happens over time,” said Lingnell.
The committee’s goal is to predict the probability of breakage due to thermal stress, such as major temperature difference exerted upon the internal and external parts of the glass simultaneously.
John Kent, president of Administrative Management Systems, explained the Insulating Glass Certification Council’s (IGCC) provisional certification.
The group created a rapid assessment chamber to measure the real-time failure of units. During IGCC’s testing, argon levels fell after relative humidity (RH) spiked. The moment of failure for these units was referred to as a “burp.”
“We plan to make this device as versatile and economical as possible,” said Kent.
IGMA members debated whether to participate in a multi-organizational revision of the product category rule (PCR) on windows to maintain products’ environmental product declaration (EPD).
The current PCR expires in September 2020.
Members voted yes to continue the conversation with the American Architectural Manufacturers Association (AAMA) and other organizations about revising the PCR.
Randi Ernst, CEO of FDR Design Inc., reported that the gas content committee is using dry ice and alcohol baths to create different frost points to test gas performance.
