Brigitte Ross and the Vetrotech team talk to exhibition attendees about their company’s fire-rated glazing.

Exhibitors and visitors convened for day two of GlassBuild America 2014 in Las Vegas today, as the more than 330 industry suppliers continued their presentation of their best and newest products.

A hot topic among many has been the increased attention on fire-resistant applications, something Vetrotech, a subsidiary of Saint-Gobain, is addressing with its fire-rated glazing products, which are used almost exclusively in commercial settings.

Vetrotech’s Contraflam is an interlayer glass product made of tempered or safety glass and filled with a transparent, intumescent layer. Scott Fox, southeast regional sales manager at Vetrotech, says the intumescent “gel” is milky white when it goes in between the lites of glass but solidifies and cures itself clear under heat.

The interlayers absorb energy from fire, reducing the transmission of radiant heat to the other side of the barrier.

Fox says that the continued focus on fire-rated glazing has much to do with the construction industry’s improved communication among sectors. “A large part of it is the architectural and code enforcement community getting on the same page with how code applies to fire-resistant glazing,” he says.

Meanwhile, Michigan-based Select Hinges is showing its hinge products, which hold a 90-minute fire rating and can be applied to glass doors. Representatives from Select say that what sets it apart is a patent the company holds in which it can add an intumescent material to bolster the fire rating to three hours.

With the company’s patented use of intumescent material, no fire pins or studs are required.

Revolving Door Green and Clear

Other companies, such as European manufacturer Boon Edam, are highlighting the sustainability and aesthetics of their products.

Boon Edam is featuring its revolving doors. Glen Tracy, national accounts manager at Boon Edam, says a major advantage of the revolving door as opposed to sliding or swing doors is that it creates an airlock instead of a wind tunnel.

“It’s a big plus for green building, providing energy savings and indoor air quality,” he says, adding that the revolving door can keep 85 percent of outside air from coming inside.

Boon Edam is featuring its Crystal TQ “all glass revolving door,” which Tracy says is the most transparent on the market.

Tracy says the all-glass doors are in high demand, particularly in hotel and office building settings, because of how they complement glass facades. The design of the doors allows the entrance to the building to remain consistent with the rest of the glass walls.

Simply put, “It’s all glass, and very little metal,” he says.

From a hardware perspective, Tesa Tape also provides solutions for achieving a less-metal, more-glass structure.

With modern construction designs seeking more transparency, Tesa’s ACX Plus double-sided acrylic tape can provide glass-to-glass bonding between edges and corners for a clean seam. It also utilizes an H-profile between lites if necessary and can be applied with glass-to-aluminum.

The use of tape, in general, reduces or eliminates the need for rivets and screws, which can mean a better glass-to-metal ratio.
