Historically, patent glazing systems featured glazing bar spacings at approximately 600mm centres. This traditional dimension was widely used but it is not a rigid standard, and the spacing can be varied significantly depending on the specific requirements of a project.
While the 600mm centre spacing provided a reliable guideline, modern advancements in glazing technology and materials have allowed for much greater flexibility. The possible width of the glazing bar centres is influenced by several key factors, which are typically specific to each project. These factors include the type and thickness of the glass used, the overall size and design of the glazing installation, structural support requirements and safety considerations.
Project-specific constraints play a crucial role in determining the optimal spacing for glazing bars. For instance, larger glass panes may require wider spacing to reduce the number of visible bars and create a more seamless appearance. However, wider spacing also demands stronger support structures and potentially thicker or more robust glass to ensure safety and durability.
Additionally, advancements in glazing materials and techniques have introduced new possibilities for customising the spacing of glazing bars. Innovations such as toughened glass, laminated compositions, and anti-shatter films enable more extensive and flexible design options while maintaining the necessary structural integrity and safety standards.
