Re: Deck glass procedures
Posted by Laszlo on Dec 3, 2007
90-degree turns with glass are a bad idea. The result is bubbles under the glass, a weaker joint and glass getting sanded away.
The bubbles come from exceeding the glass' minimum bend radius. The glass can't make the turn so it peels away, letting air underneath.
It's a weaker joint because the glass is folded, instead of bent. The fold is a stress concentrator, resulting in a line of weakness.
Option 2 would leave the glass vulnerable to peeling off. You really ought to have at least a 2 inch overlap to avoid this, but I'll bet your rubrails are thinner than that.
