When our Anderson fogged up, we had to get a new insulated unit from them.
It has a proprietary molding that is part of the insulated unit, cost was
$270! I was a bit disappointed when it came. They went cheap and used single
strength glass. The original was double strength. It is 18x72 inches. Kind
of a large span for such thin material. I use single strength glazing for
picture framing and it seems very flimsy at over 36" on the longest side.

Outside of this, these 25 year old windows have been very good. Only one
unit has fogged so far.

It's an Anderson casement set consisting of three double-paned
windows. A deer charged it, and now one of the panes has an 18-inch
vertical crack.

Can a glass company merely replace the one pain, or does the fact that
it's a double paned window complicate matters? Does the entire set
need to be replaced? TIA, Jack
