Glass Stairs and Flooring

Construction of glass flooring and stairs, when executed correctly, can be both stunning and functional. Sightlines, privacy, and safety are the three major concerns when contemplating the use of glass, but the after-effect is worth it.

One highly acclaimed installation is the gorgeous, LED-lit floating staircase at a residence in Aspen, Colorado. Each stair was laminated in a 3-ply format to provide stability and reflect the LED lighting to create a beautiful visual aesthetic. A clear HT Frit was applied resulting in a high traction surface that doesn't impede upon the overall perception.

Safety is one of the largest concerns when working with glass, whether it be in manufacturing, installation, or everyday use. Glass is naturally a non-porous, smooth building material, which is desirable for many circumstances. However, when applied as flooring or stairs, public safety must be the top priority. Laminating or tempering provides safety measures in the unfortunate event of breakage, but Traction Control Frit offers protection against slips and falls.

Goldray's Traction Control ceramic frit, also called TC Frit, is ideal for flooring, stairs, and skylights. The texture has a rough consistency, similar to that of medium-grain sandpaper. When applied in a definitive pattern, TC Frit is not only highly functional but also provides decorative appeal. The aggressive traction properties of this product yield a superior slip coefficient, a safety feature for glass flooring.

At Goldray we believe Every Building Deserves To Be Beautiful, which is why we work with our clients to ensure their vision becomes a reality, without compromising safety or aesthetics.
