When Bill Lingnell Speaks, People Listen

November 1st, 2021 by Chris Collier

The Fenestration and Glazing Industry Alliance’s (FGIA) Hybrid Fall Conference played host to several insightful sessions recently, including code updates from the International Code Council (ICC) revealed and safety tips from Sentinel Security Group founders. During a bonus session, FGIA technical consultant of glass products Bill Lingnell answered questions surrounding quality, compatibility and performance requirements for insulating glass units (IGUs).

Lingnell has more than 55 years of experience in the technical applications of glass and architectural products. His career involvement includes significant building projects throughout the U.S., Canada and other countries. At the end of his one-hour presentation, Lingnell provided answers to several pertinent industry questions.

Q: What is the best way to determine what is compatible and, in particular, if you’re introducing a new component?

Lingnell: There’s a lot of tests that the suppliers use to validate their products before they get out to market. Usually, if you’re going to do a compatibility test, those suppliers [are] anxious to help you out [with] whatever it is you’re using in conjunction with another material … It’s a matter of coordination [concerning] the materials being used. There’s no definite path, but the logical path is to get all those available regarding what’s going to be used in that particular system.

Q: In order to help prevent IGU seal failures, what should an insulating glass fabricator do?

Lingnell: Some folks feel they have a quality program, but I challenge you to say, ‘Okay, do you know what the cost of your quality is?’ That’s a question for management, as well as the quality supervisor. Once you find out what that is, you know whether or not you’re going to be making quality products and what you have to do to get there. My encouragement to fabricators is to get all of the documents, guidelines [and] put into place the things you need to do to run an organization that’s smooth, quality-oriented and [has] high-production capabilities. But follow all of the guidelines that are available to you and do good practices for making your units.

Q: Is there a simple definition for quality, and how do some companies measure it?

Lingnell: I was fortunate to attend some quality seminars back when I was working for a glass company. . . . They made me the head of a quality improvement program and they sent me to [a] quality college. I learned a very simple definition for quality: ‘Quality is conformance to requirements.’
