Pilkington Profilit

Translucent Linear Channel Glass System

QUOTE| |800.426.0279

The Pilkington Profilit™ channel glass wall system consists of self-supporting cast glass channels and an extruded metal perimeter frame. The end result is a wall that obscures vision but allows light to pass through. It can be used in interior or exterior applications, and installed vertically or horizontally.

“It lets in light, allows for privacy and is visually interesting day or night.”

-Jim Graham, principal, Graham Baba Architects

  • May be tempered or filmed to meet impact safety requirements
  • Allows passage of light while maintaining privacy
  • May be insulated with Lumira® aerogel for energy efficiency
  • Sound insulation (up to 42 db uninsulated, 44 db with Lumira aerogel insulation)
  • Can be utilized in curved walls
  • Installs vertically or horizontally
  • Aluminum perimeter frame provides additional structural strength
  • Interior applications may be installed into wood jambs or millwork instead of TGP’s aluminum framing
  • Minimal maintenance
  • Proven performance – used in Europe for more than 30 years
  • Most channels available with pinstripe wires
  • View perimeter framing system

Pilkington Profilit has been tested to meet the following standards: AAMA 501.4, AAMA 101, AAMA 1801-97, AAMA/NWWDA 101/1, S.297, ASTM F 588-97, NFRC 100-97, ANSI Z97.1-1984, CPSC 16CFR 1201, Category II (with safety film). All testing carried out by Architectural Testing Inc., York, PA. Formal test reports are available by contacting Technical Glass Products.


For added energy efficiency, Pilkington Profilit can be filled with Lumira® aerogel, a new class of lightweight insulation material produced by Cabot Corporation which is ideally suited for daylighting design. Lumira aerogel promotes soft, even light dispersion, reduces unwanted noise and resists condensation. TGP is the exclusive supplier of Lumira aerogel for channel glass systems.

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.
