We have just experienced at our home a massive (100+) window failure. This involves Andersen HP windows manufactured in 1992. I understand failure has been a problem -spontaneous shattering and leakage - with the glass used in these windows during 1991 and 1992. The windows have a 20 year warranty on the glass and Andersen will replace them but there are naturally a number of related costs. Are there any other homeowners or contractors out there who have had a similaar problem with these windows and would be willing to share how they resolved the problem with Andersen?
