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. For added energy efficiency, see Pilkington Profilit with Lumira® aerogel insulation.

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. The exceptional thermal performance of Lumira aerogel helps increase energy efficiency. Lumira aerogel also promotes soft, even light dispersion, reduces unwanted noise and resists condensation.  TGP is the exclusive supplier of Lumira aerogel for channel glass systems.


Increases Light Diffusion: Eliminates glare, allows soft, even, light dispersion
Improves Acoustic Performance: Minimizes unwanted noise
Exceptional Thermal Performance: Reduces heat loss and minimizes solar heat gain
UV Stable: Maintains performance over time
Resists Moisture: Prohibits growth of mold, mildew and fungus
Provides Green Solutions: Reduces building design loads and conserves energy
Adheres to Guidelines: Meets and exceeds strict building codes

Pilkington Profilit should be installed in accordance with approved shop drawings -- plumb, level, square and free from warp or twist while maintaining dimensional tolerances and alignment with surrounding construction.

Erect framing, vinyl spacer and glass in accordance with manufacturer's printed installation instructions. Seal glass units continuously on both sides of glass between frame and glass and between linear glass units. Install perimeter joint sealant and backing materials between assemblies and adjacent construction.


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.
