Approximate Weight of Architectural Flat Glass

Design professionals often need the weight of materials for engineering and construction site considerations. This table provides approximate weights of architectural flat glass by thickness designations as published by North American manufacturers.

Approximate weights do not apply to patterned glass or products incorporating multiple lites of glass fabricated into an assembled product. Additional glass thicknesses are available.

Individual manufacturers should be consulted for detailed product availability. If the exact thickness is known, the exact weight may be calculated using a glass density of 158 pounds/ft3 (2531 kg/m3).

This material is excerpted from an informational bulletin developed by the Glass Association of North America (GANA) flat glass manufacturing division and approved by the membership and the GANA board of directors. For more information about GANA, visit its website www.glasswebsite.com.
