Dlubak is one of the country’s principal suppliers of bent or curved glass to the architectural glazing industry. We offer a full line of glass products for any architectural application. Our production capacity and ever-expanding processing capabilities allow us to offer you curved glass in a wide variety of sizes in many composites including laminate and energy efficient dual sealed insulating units. Dlubak’s curved glass is the product of choice for all architectural applications such as exterior vision and spandrel areas, skylights, solariums, covered walkways, interior walls and hand rails.


  • LAMINATED GLASS – with polyvinyl butyral (PVB) or SentryGlas™

  • CLEAR GLASS – all types including LOW-IRON
  • TINTED GLASS – all substrates
  • SILK-SCREEN GLASS – ceramic frit patterns

Girth (arc length) and height:

  • Monolithic and non-laminated curved insulating glass can be produced in sizes as large as 100” x 170”. However, shipping, handling, and safety considerations should influence the maximum size to be processed for a given project.
  • Laminated glass can be produced as large as 96” at the chord or “point to point” dimension. The height dimension can be 17′ or 204″ maximum

Maximum and minimum sizes depend on composition, glass plies, size, glass ply thickness and bend detail.
