Redefine the possibilities of construction

Get Started

When specifying oversize glass, there are some technical considerations to keep in mind. As glass gets bigger, more surface area is exposed to outdoor elements. Heat-treated glass is recommended to help increase strength and resistance to wind loads and help reduce the risk of thermal breakage.

  • Glass thicker than a standard quarter inch (6mm) may be recommended to help keep secure within the frame, prevent edge pull out and maintain glass deflection.
  • Movement of the oversize IG unit can add stress to the IG seal. A wider than standard sealant bite may be needed for larger sizes.
  • Please confirm that the finished IG units can be fabricated by the Guardian Select Fabricator for your project.
