Minimum and maximum sizes

Illustrations for Catalogues

To determine the minimum and maximum sizes available for finished glass products, the glass fabricator must be consulted. Physical/mechanical capabilities and constraints of the fabricator will affect the final finished glass size availability.

Special considerations for oversized glass: IGUs and heat treatment

It’s important to understand that not all fabricators are equipped to process and/or heat-treat standard glass sizes. Minimum and maximum sizes are dictated by:

  • The size of glass available from the primary manufacturer
  • Any limitations in the fabricator’s equipment
  • The capabilities of the contract glazier
  • Availability of specialized shipping and handling equipment (particularly for oversize units)
  • Specific glass type: silk-screened, heat-treated, laminated, etc.
