Sustainability Challenges

Sustainability challenges for glass and glass products include:

  • Limited to no insulating value when used in fenestration;
  • Limited life spans of sealed window units due to gas fills and seals;
  • Glass window assemblies that may contain toxic materials (e.g., lead came and asbestos in putty);
  • Glass, which can be damaged with limited force (varies on thickness and type), requiring premature replacement.
