What is Bent Tempered Glass?
A creative alternative for architects and designers, Oldcastle BuildingEnvelope™' exclusive Bentemp® is a tempered or heat-strengthened glass that is bent, during the heat-treating process, to a specified radius to create unique profiles for installations in commercial and residential applications. Bentemp® glass can be fabricated with holes, notches, hinge cutouts, pattern cuts, polished, ground and mitered edges.

What is Bentemp?

A creative alternative for architects and designers, Bentemp® is tempered or heat-strengthened glass that is bent, during the heat-treating process, to a specified radius to create unique profiles for installations in commerical and residential applications.


Where should I use it?

  • Handrails and Spiral Staircases
  • Shower Enclosures
  • Partitions and Elevator Enclosures
  • Commercial/Residential Windows
  • Curtain Walls and Storefronts
  1. Bentemp®: Heat-treated glass, typically specified as fully tempered, that is heated, then bent to create unique profiles
  2. Fabrication: Bentemp® glass can be fabricated with holes, notches, hinge cutouts, pattern cuts, polished, ground and mitered edges.
  3. Max. Size: 82"(H) x 142"(W)
    Min. Size: 20"(H) x 20"(W)
    Sizes do not apply to all thicknesses.

Bentemp® is offered in a large variety of glass products, including clear, low iron, Low-E’s, standard or high performance (spectrally selective) tints and reflective, to achieve desired aesthetics and to meet design criteria.

Bentemp® glass is custom-tempered by heat-treating glass through a horizontal tempering furnace. Although Bentemp® glass is usually specified as fully tempered, Bentemp® glass can be heat-strengthened for applications where fully tempered glass is not required.

Capabilities

Thickness: 1/4" (6mm), 5/16" (8mm), 3/8" (10mm), 1/2" (12mm), 5/8" (15mm), 3/4" (19mm)
Monolithic Size Requirements: Max: 82" x 142",
Min: 20" x 20". Maximum size varies with radius and thickness of glass.
Insulating Glass: Max: 82" x 140", Illinois only,
Max: Outside Illinois, 82" x 130"
Many variables affect production capabilities.
Spandrel: 1/4" (6mm) substrates only
Max: 72" x 120", Min: 20" x 20"

Applications
Typical applications include glass handrails, spiral staircases, custom shower enclosures, curved ceramic frit spandrel glass, revolving doors, partitions and insulating glass units. Depending on the application design, there is specific information that will be required to ensure accuracy.

Characteristics
Distortion exists in all tempered and heat-strengthened glass, and bent configurations may even exaggerate it. Bent-tempered or heat-strengthened glass is not recommended for vision areas, where distortion is not an acceptable characteristic. Minor departures from exact straightness are inevitable, and some linear distortion may also exist. Strain patterns are inherent in Bentemp glass and are more visible under certain light conditions.
