UPDATE...
I called the company who sold/installed the windows this past Monday morning and spoke to the manager. I explained what happened. He laughed so hard I expected to hear him fall down.
When I told him that I had broken one probably before his crews got their trucks unloaded, that escallated the hilarity...
He told me that I had probably set a new company record for the earliest broken window...
Then, we talked and determined which window it was, and he said "No problem. I'll have the replacement here on the 30th." IF tit hadn't been Thanksgiving week, it would have been here yesterday (Black Friday) Since only the inner pane was broken, and the house is still weathertight, there was no reason to put an emergency rush on the replacement.
Gotta say, the new windows are a delight! The house was built about 10 years ago, and (of course) the contractor put in the cheapest contractor-grade windows he could find. Many of my neighbors have experienced the same problems that we did: inner gas seal broken so the windows are no longer energy efficient, condensation between the panes, black mold forming around the windows because of all the moisture condensing on the aluminum frames, etc.
A nice side-benefit of these windows is that the Low-E coating also helps reduce sound transmission. The house is now MUCH quieter than it had ever been, and with the family of Illegal Mexicans (or so I believe about many of them) living next door and playing their oompa-oompa cucaracha music at max volume anytime they're outside, the sound-dampening effect is a definite plus.
Haven't had to turn on the furnace yet this year, even though we've had almost a week of lows in the mid-30's. With the old windows, we'd have had that sucker cranked up the first night.
While I doubt I'll see the massive reduction in heating/cooling costs that the sales people claim, any reduction is a good thing, and any increase in comfort in the house is also a good thing.
