The glass type and thickness will depend upon a number of factors, including:

• Pane size (width x height)
• Edge support conditions (e.g. fully framed, top and bottom edge supported, etc.)
• Distance from internal finished floor level to bottom edge of glass
• Design wind load and snow load for the project (in kN/m²)
• Design barrier loads for the project (e.g. line load, infill UDL, concentrated load, etc.) – where the glass is protecting a difference in floor loads
