Fire-Rated Glass Options

3/16" FireLite Standard – Fire-Rated Ceramic Glass

FireLite Standard is a 3/16" ceramic fire-rated glass designed for fire-protective glazing applications where impact-rated safety glazing is not required.

Unlike ordinary window glass, ceramic fire glass is engineered to withstand the extreme temperatures associated with a fire while remaining within the opening for its designated fire rating.

FireLite Standard is an excellent choice for qualifying interior fire-rated wall openings where safety glazing is not required.

Specifications:

  • Product: FireLite Standard
  • Glass Type: Fire-rated ceramic glass
  • Thickness: 3/16"
  • Fire Rating: Up to 90 minutes, subject to approved size and assembly
  • Light Transmission: 88%
  • STC Rating: 35
  • Safety Rated: No
  • Typical Application: Interior fire-rated wall openings where safety glazing is not required

Important Safety Glazing Limitation

FireLite Standard is not impact-rated safety glass.

It should not be selected for hazardous locations where applicable building codes require safety glazing, such as certain door, door-adjacent, and low-level glazing applications.

Where safety glazing is required, select an appropriate safety-rated product such as FireLite-NT or FireLite Plus based on the requirements of the opening.


3/16" FireLite-NT – Fire-Rated Safety Glass

FireLite-NT combines fire-rated ceramic glazing with a surface-applied safety film to provide both fire protection and impact safety performance.

This makes FireLite-NT suitable for approved applications where fire-rated safety glass is required, including qualifying doors, sidelites, transoms, and other hazardous locations.

Specifications:

  • Product: FireLite-NT
  • Glass Type: Filmed ceramic fire-rated safety glass
  • Thickness: 3/16"
  • Fire Rating: Up to 180 minutes, depending on application, size, and listed assembly
  • Light Transmission: 88%
  • STC Rating: 35
  • Safety Glazing: Impact-rated configurations available for applicable requirements
  • Standards: ANSI Z97.1 and CPSC 16 CFR Part 1201, as applicable
  • Typical Applications: Doors, sidelites, transoms, and fire-rated wall openings

FireLite-NT provides the thin profile and high visibility of ceramic glazing while adding the impact performance required for many locations where ordinary non-safety-rated fire glass cannot be used.


5/16" FireLite Plus – Laminated Fire-Rated Safety Glass

FireLite Plus is a laminated ceramic fire-rated safety glass designed for applications requiring fire protection, impact safety, and increased glazing durability.

Its laminated construction makes FireLite Plus an excellent option for qualifying fire-rated doors, windows, sidelites, transoms, and other openings requiring safety-rated glazing.

Specifications:

  • Product: FireLite Plus
  • Glass Type: Laminated ceramic fire-rated safety glass
  • Thickness: 5/16"
  • Fire Rating: Up to 180 minutes, depending on application, size, and listed assembly
  • Light Transmission: 85%
  • STC Rating: 38
  • Safety Glazing: Impact-rated configurations available for applicable requirements
  • Standards: ANSI Z97.1 and CPSC 16 CFR Part 1201, as applicable
  • Typical Applications: Fire-rated doors, sidelites, transoms, windows, and approved interior or exterior applications

The laminated construction also helps retain glass fragments if breakage occurs, providing additional durability compared with non-laminated ceramic glazing.


1/4" WireLite-NT – Wired Fire-Rated Safety Glass

For projects requiring the traditional appearance of wired glass, WireLite-NT combines a diamond-pattern wire grid with fire-rated and impact-safety performance.

WireLite-NT can be used in qualifying fire-rated doors, sidelites, transoms, and windows where its rating, dimensions, and listed assembly meet the requirements of the opening.

Specifications:

  • Product: WireLite-NT
  • Glass Type: Wired fire-rated safety glass
  • Pattern: Diamond wire
  • Thickness: 1/4"
  • Fire Rating: Up to 90 minutes, depending on application, size, and listed assembly
  • Light Transmission: 77%
  • Safety Glazing: Impact-rated configurations available for applicable requirements
  • Standards: ANSI Z97.1 and CPSC 16 CFR Part 1201, as applicable
  • Typical Applications: Doors, sidelites, transoms, windows, and other approved fire-rated openings

WireLite-NT provides the familiar appearance of traditional wired glass while addressing impact-safety requirements applicable to many modern commercial openings.

Which Fire-Rated Glass Do I Need?

Choosing the correct fire-rated glass depends on more than just the number of minutes required.

The location of the glass, dimensions of the opening, type of frame, required fire rating, impact-safety requirements, and applicable building code all affect which product can be used.

As a general guide:

Product Thickness Safety Rated Fire Rating* Common Use
FireLite Standard 3/16" No Up to 90 min. Fire-rated wall openings where safety glazing isn't required
FireLite-NT 3/16" Yes* Up to 180 min. Doors, sidelites, transoms & wall openings
FireLite Plus 5/16" Yes* Up to 180 min. Doors, sidelites, windows & higher-durability applications
WireLite-NT 1/4" Yes* Up to 90 min. Wired-glass doors, sidelites, transoms & windows

*Actual allowable fire rating, safety rating, dimensions, and application depend on the specific glazing configuration and listed assembly.

Fire-Rated Glass for Doors

Glass installed in a fire-rated door has requirements beyond those of ordinary architectural glazing.

The glass, door, lite frame, hardware, dimensions, and complete opening must be appropriate for the required fire rating.

Because door glazing is also commonly located in an area requiring impact safety, non-safety-rated FireLite Standard should not be substituted for an appropriate safety-rated product where safety glazing is required.

For qualifying door applications, FireLite-NT, FireLite Plus, or WireLite-NT may be appropriate depending on the project's requirements.

Fire-Rated Glass for Windows & Walls

Ceramic fire-rated glass is an excellent solution for approved vision openings in fire-rated walls because it can withstand substantially higher temperatures than ordinary architectural glass.

For wall applications where impact safety is not required, FireLite Standard provides a cost-effective fire-protective glazing option.

Where the window is located in a hazardous location requiring safety glazing, select an appropriate fire-rated safety glass instead.

Fire-Rated Glass vs. Tempered Glass

Standard tempered glass and fire-rated ceramic glass are not interchangeable.

Tempered glass is heat-treated primarily to improve strength and provide safer breakage characteristics. It should not be assumed to provide the fire rating required for a protected opening.

Fire-rated ceramic glass is specifically engineered and tested for use in qualifying fire-rated glazing assemblies.

When a project requires both fire protection and impact safety, an appropriate fire-rated safety glazing product must be selected.

Fire-Protective vs. Fire-Resistive Glass

This is an important distinction when specifying fire-rated glazing.

Products such as conventional ceramic fire glass are generally classified as fire-protective glazing. They are designed to resist flames and smoke for their designated rating but do not necessarily provide the heat-blocking performance of a fire-resistive wall assembly.

Fire-resistive glazing systems are designed and tested to limit radiant and conductive heat transfer in addition to resisting flames and smoke.

If project documents specifically require a fire-resistance-rated wall assembly or a temperature-rise/heat-transfer limitation, verify that the selected glazing system satisfies those requirements rather than selecting a product based solely on its minute rating.
