Pilkington Profilit

Translucent Linear Channel Glass System

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

Testing

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.

Insulation

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.
