Glass flooring systems have become increasingly popular over the past few decades.  Utilizing glass into the floor provides a unique walking surface while allowing light to penetrate below to surrounding areas.  Glass floors can be one of the most cost effective ways to add more natural light between floors as opposed to traditional artificial lighting.  Looking to create an advanced glass flooring system, SAFTI FIRST developed a fire resistive glass floor.  Fire resistive glass floors still allow for natural light to penetrate areas below while providing a fire rating of up to 120 minutes depending on application. 

Glass floors requiring a fire rating are intended to stop the spread of fire by acting as a barrier.  Traditional non-fire rated glass floors will break under the pressure of fire, similar to any non-fire rated window assembly.  This advanced fire rated glass floor system meets ASTM E-119/UL 263/ ULC-S101 up to 2 hours.  Additionally, the GPX Fire Floor System has the largest tested and listed fire rated glass floor panels for fire rated assemblies that are fully captured and butt-glazed.

Fire Resistive Glass

GPX FireFloor System is a fire resistive glass floor assembly.  What does it mean for glass to be fire resistive?  Fire resistive glass contains smoke, flames, and block the passage of radiant heat.  It limits the temperature rise on the non-fire side to 250°F above ambient even when the other side reaches temperatures over 1800°F.  Fire resistive floors are used in the same way designers utilize glass walls - to enhance the amount of natural light passing into a building. 

Fire Rated Glass Floor Installation

Fire resistive glass floor systems should be installed by a licensed contractor and following all approved shop drawings.

Project Highlight: 21C Museum Hotel

1 Hour Fire Resistant Glass Floor System

21c Museum Hotel in Nashville, TN features a glass floor on the 2nd level acting as a light well.  The transparent floor was required to meet a 1-hour fire resistive rating.  SAFTI First was able to work with the architect and glaziers to design a single glass unit comprised of non-slip rated Starphire tempered laminated glass.  The GPX FireFloor system was easy to install, which reduced the labor costs, giving this system even more appeal to the design and construction team.  The code-compliant fire rated glass floor certainly made a dramatic impact on the space.
