As a consulting specifier, my clients come to me for my expertise, and to bolster my knowledge I frequently find myself in conversations with product reps, talking about the nitty-gritty technical aspects of their products. These conversations delve into a far deeper level of detail than I would previously get when I was a ‘normal’ design architect and project manager. Over the course of those conversations, I am occasionally surprised that things I thought I knew a lot about were based on misconceptions. In fact, even things that I considered “common knowledge” have been shown to be wrong, or at least over-simplifications. Armed with accurate information, I can pass correct technical advice on to my clients, hopefully dispelling those misconceptions one person at a time, one project at a time.
Which leads me to the idea for this series of posts. Misconceptions can be found across the spectrum, in every product category and in every MasterFormat number. I thought it would be fun and enlightening to ask my go-to reps in a wide variety of product categories to tell me the biggest and most common misconceptions they hear as they work with designers and architects, and present their responses here. In each post I’ll relate my discussion with reps in one category or one MasterFormat header. So without any further ado, today’s Misconceptions.
The reps I chose to approach for this post, Andy Vegter from USG and Thad Goodman from National Gypsum, are both active and involved CSI members that I’ve come to know well over my career. I consider them my trusted advisors when it comes to questions about their companies’ lines of gypsum-based products. I’m not promoting their products over their competitors’ - it’s far more about the individual reps than the companies that they work for.
Without any further ado, today’s Misconceptions.
09 29 00 - Gypsum Board
I asked Andy and Thad this question:
“When you think about the questions and comments you hear from design professionals across all levels of experience, what misconceptions about gypsum products do you find that you most commonly have to dispel?”
First, this brief introduction - What is gypsum/gypsum board, anyway?”
Gypsum is a natural mineral, chemically made up of calcium and sulfur bound to oxygen and water. It is found naturally in sedimentary rock formations, with some of the world’s largest natural reserves in North America. A synthetic version, which is a byproduct of coal burning electric power plants, is chemically identical to natural gypsum. Some gypsum board manufacturing plants are fed with mostly synthetic gypsums and others are built over a mine where the gypsum is coming out of the ground. Synthetic gypsum is considered a recycled material by sustainability rating systems, so projects seeking certification can specify that gypsum panels be made up of 90% recycled content. It’s important to remember that not all products are available from plants that use synthetic gypsum.
Gypsum board is manufactured when gypsum is mixed with water and additives to form a slurry which is then fed between continuous layers of paper or another type of facer. Through a chemical process, the slurry hardens to its original rock state, and the facer becomes bonded to the gypsum core. The boards are then cut to size and dried.
What follows are some of the most frequent misconceptions and misunderstandings that the reps related, followed by the correct information.
