Fire-Rated Frames

60/120 Minutes


Designed for Hurricane applications (maximum design loads up to +/-110 psf)---highest wind load of any fire-rated curtain wall on the market, Fireframes® Curtainwall Hurricane Series incorporates precise European engineering resulting in narrow steel profiles.

“TGP's technical expertise and service enabled us to achieve a matching look across the curtain wall assemblies.”

-Andrew Anderson, associate principal, Grimshaw Architects

  • Maximum design load up to ± 110 psf
  • Narrow steel profiles
  • Air and water pressure tested and approved for exterior use
  • Easy installation similar to typical pressure plate curtain wall
  • Insulated glass unit (IGU) comprised of large panes of Pilkington Pyrostop® fire-resistive-rated glass and HVHZ glass (high velocity hurricane zone for large missile)
  • 60 minute Pilkington Pyrostop is also available with a translucent interlayer
  • Frames supplied "K-D" (knock-down) or welded depending on application
  • Pilkington Pyrostop fire-resistive-rated glass is composed of Pilkington OptiWhite™ glass and clear intumescent interlayers
  • Durable steel frames ensure low maintenance system
  • Finished face caps (aluminum, stainless steel, etc.) to meet project needs
  • Custom aluminum face caps to meet project needs
  • Finish painted at the factory to match desired color scheme

* 60 and 120-minute tests conducted per UL 263 / ASTM E-119. Therefore assembly is classified as a wall assembly, and not subject to “opening” area limitations.
Note: Individual lite sizes cannot exceed “Max. Exposed Area” shown above.

Product Data

For technical data, including Pilkington Pyrostop® for Fireframes® Curtainwall Hurricane Series, view product fact sheet.

The time, in minutes or hours, that materials or assemblies can be expected to prevent flames and smoke from spreading.

As heat develops within the source area, pressure within the enclosed room begins to build relative to the pressure outside. Once the fire reaches equilibrium in the positive pressure zone, smoke, hot gases and flames are forced through any openings in the door or window assembly. Testing to the UL 10C standard more closely simulates real fire conditions.

Blocks radiant and conductive heat transfer from one side of the glass to the other. A required characteristic of glass used as a wall.

Classified and labeled by Underwriters Laboratories, Inc.® (UL), an independent product safety certification organization.

Immediately following a furnace test, heated glass is subjected to water from a fire hose. The cooling, impact and erosion created by the hose stream tests the integrity of the glass. In the U.S., the hose stream test is required for all fire ratings over 45 minutes (all fire ratings require it in Canada).

Available as a temperature rise door with Pilkington Pyrostop® fire-resistive-rated glass for 60-90 minute applications

Temperature rise doors provide a barrier to radiant and conductive heat transfer.

Available in stainless steel frame finish options for increased design flexibility.

Building codes clearly define hazardous locations where impact safety glass is required. Glass with this designation has been tested to meet impact safety requirements required for areas such as doors, sidelights, and areas close to the floor.

FireLite IGU is a fire-rated insulated glass ceramic unit that also complies with energy codes. It is designed for use in exterior applications where energy codes require an insulated product, or for interior applications with special needs such as sound reduction.

Withstands continuous temperatures to 1292° F for use in high efficiency heating appliances.

The ability of glass ceramic to withstand sudden heating, cooling, or both without cracking, shattering or exploding out of the frame.

The ability of the glass to stop various types of ammunition. Ratings are assigned in levels from 1 to 8, with a Level 8 rating being the highest (able to stop a 7.62mm rifle lead core full metal copper jacket, military ball).

The capacity of an element in a building structure to support a weight in addition to its own.

Listed and labeled by Intertek, an independent assurance, testing, inspection and certification organization.

Glazing designed to increase the amount of time required to gain entry. This additional time is intended to allow for the enactment of lock-down protocols and to allow for the arrival of emergency response teams. May be used in areas with high risk of prolonged attack or in critical areas such as vestibules. Forced entry resistant glazing should also resist penetration from hand-held or hand-thrown objects such as hammers, crowbars, bats, knives, bricks and rocks.
