Our sliding doors are made of laminated glass. Each pane of glass is actually 2 panes of glass stuck together, back to back, with a piece of clear laminate. If anyone crashes into the glass door, the laminate will hold the glass pane together preventing severe glass cuts from slivers of glass projectiles that could fly into eyes and cause cuts. Unfortunately for us, we were given glass panes that were of rather poor quality and thus, the 2 panes of glass are detaching themselves from the laminate. The architect informs me that this is a process called Delamination.
Together, the 2 panes of glass stuck together are 11mm thick. Separately, each pane is only 5mm thick. Separated from each other, they are very fragile. The whole pane of glass loses its strength and could even crack merely from strong winds. Obviously, in the process of cracking, sharp slivers of glass will be projected all over.
For those of you who will be building your houses, please ensure that the glass manufacturer provides a warranty of at least 10 years on your glass. Don't make the same mistake we did.
