Historic Private University: New Dorms Demand Faster Firestopping

This historic private university in Indiana recently made a major announcement: students will now be required to live in on-campus housing through their their first six semesters (meaning, typically, their junior year of college). This new requirement would be easier said than done, however — it would require the university to construct several new buildings to house all these students, and quickly.

Huge multi-unit buildings like dorms come with a long list of code requirements, especially between units. And with hundreds of individual units, the man hours that fire caulk requires can turn into man days, weeks and even months. Sealants are tricky to get right — inspections are easy to fail, and re-dos are frequent — and messy either way. So, when the project’s interior contractor Gibson-Lewis discovered a faster, simpler firestopping method from Trim-Tex that ditches fire caulk, it was a huge breakthrough.

Gibson-Lewis selected a few of Trim-Tex’s trailblazing fire rated drywall accessories for this project: Fire Bead, Fire Gasket and the Fire Rated 093V Expansion. In this story, we will hear from the contractor's drywall crew, primarily about how Fire Bead made their lives easier and their work faster. (Next time, the project’s carpenters will tell us more about Fire Gasket.) Check out the video below, and read on to learn more!

Fire Bead: ‘Any of my finishers can put it on’

For any walls that called for a fire rating, the drywall crew would “picture frame” the walls with Fire Bead: installing it in the head-of-wall gap, and in the vertical joints running up the sides. (Meanwhile, on the bottom track, the carpenters had already installed Fire Gasket before the drywall had even been hung.) For non-fire rated walls, the same picture-framing process was used, but using Trim-Tex's Deflection Bead — the same solution as Fire Bead minus the firestopping abilities.

For Gibson-Lewis Drywall Foreman Jesus Gutiérrez, the benefits of Trim-Tex’s Fire Bead came down to two things: simplicity and speed.

“This is our first time using the Trim-Tex stuff,” Gutiérrez told us. “To me, it's been a big advantage because we're skipping the step of having to caulk it all, or having to find a guy good enough to do it. It seems simple enough to do the caulking, but it's usually a messy process, and you usually don't want to take somebody who's one of your better workers — it usually goes to somebody like an apprentice or something, so it ends up being a mess. Where this stuff, any of my finishers can put it on.”

‘Our processes are farther along than where we would've been’

Fire Bead is a wall-mounted vinyl L bead, outfitted with a tear-off strip to protect any abutting substrate from joint compound, as well as a flexible bubble gasket at the bead’s apex that provides protection for up to ½” of building deflection. Then, attached to the bead’s interior flange, there’s an innovative strip of intumescent tape. If a fire were to start in one unit, the heat would cause this tape to expand to 30 times its size, blocking off the wall joint and stopping fire or smoke from passing through it.

As you can see, in every piece of Fire Bead, there are several complex components. So why did this drywall crew find it so simple to use? Well, despite all the added features, actually installing the bead will be nothing new to any seasoned drywaller; installation is quite similar to that of a Trim-Tex Tear Away L Bead, which most commercial drywall finishers use all the time. Fire Bead takes the drywall accessory installation and the firestopping process and condenses them down into one step.

“I definitely think it’s saving labor,” says Gutiérrez. “Because now, if I got to touch it — finishing it — to begin with, if I got to do something to finish the outside, which usually involves some kind of product like a Trim-Tex backless Tear Away or something, I have to have a guy fire caulk it first. Now, the same labor I'm using to put on the Trim-Tex Tear Away, I'm using to put on the Trim-Tex fire rated gaskets, and that makes a big difference. Just taking out that one step … it’s helping us move along. I feel like our processes are farther along than where we would've been if I would've had to take man days to fire caulk.”
