Only select portions of the ground-floor exte-
rior were required to provide fire protection by
code,” says Razwick. “The monolithic aesthetic
of [our system] helped make it possible to create
smooth visual transitions at these junctions.”
Sometimes, fire-rated glazing manufacturers are
challenged with trying to help remediate a predic-
ament created by an oversight or judgment by the
project team after the project is well underway.
Nass says he often fields calls in which a project
team realized it has to meet certain fire require-
ments in an area of the exterior where it initially
specified a non-rated product.
This is a situation where they were designing
around non-rated suppliers,” says Nass. “And of
course, with architects and glass, bigger is better,
and with a few intermediates as possible. But
when you test and list a fire-rated product, you’re
bound by the restrictions and limitations of what
you tested, while those same limitations don’t
apply to non-rated products.”
We are the first manufacturer to provide a complete structural system for your
walkable skylight, glass deck and glass flooring projects. Our systems are
self-supporting and are available in standard units, as well as custom sizes. We
offer a variety of standard anti-slip walk on surfaces in addition to custom cast
or organic textures. Glass Flooring Systems Inc. provides an extremely cost
effective solution for a feature which is often value engineered out of a project.
He adds that while manufacturers are often
able to come up with a solution, “the design com-
munity has to understand that there are limita-
tions to those rated products. Our job is to make
those limitations the least impactful as possible
from an aesthetics standpoint.”

Meeting the Needs

With the increase in fire-rated glass on the exteri-
or, applications are getting more and more unique.

We had quite a few engineers working on that
project to ensure it passed testing for an earth-
quake or blast event,” says Traynor.
Air and water performance is another key con-
sideration for architects.
While not all projects are this intricate, the
fire-rated glazing industry continues to position
itself to meet the wide-ranging needs of the archi-
tectural community—even the most basic ones.
Energy efficiency is a leading driver in modern
design, and the building envelope plays a critical
role. The fire-rated industry addresses this by
implementing its products in insulating glass units
and solar control applications, and incorporating
thermal break technology when needed.
“As a part of the exterior building envelope, it’s
crucial for the fire-rated glazing system to stand up to
fire, as well as the day-to-day elements,” says Razwick.
“… The same factors that are considered with non-
fire-rated aluminum curtainwall performance also
carry over to best practices when it comes to fire-rat-
ed system design.”
