Spontaneous Breakage of Glass

Sometimes glass breaks in a building without any obvious cause. When this occurs, it could be due to glass edge damage or surface damage from handling and glazing that then weakens the glass during high winds, building or framing system movement, vandalism or a specific type of inclusion inside the glass. There are more than 50 types of inclusions in float glass, and while the most widely discussed is a nickel sulfide stone, this type of inclusion actually occurs very rarely.

Heat Strengthened vs. Tempered Glass

When thinking of some of the world’s most dramatic, visually breathtaking buildings, they most likely involve large expanses of glass. Before these architectural masterpieces can be created, the glass may need to be heat-treated for durability and/or safety reasons. The type of processing required—heat-strengthening or tempering—depends on the glass’ specific application.
