Bill, I don't really know how to calculate the heat loss for an old double hung with storm VS a double pain, but there are lots of claims out there that say the difference is significant. Although, a lot of those claims are coming from the windows sales people. *GRIN*
This kind of thing does tend to increase the value of the house, but only by some fraction of the original cost of the windows. So, between getting some back via a home sale, and saving some on heating bills before you sell, it probably comes out in the wash before too many years. I think you are out of luck on the tax credit thing. I am pretty certain that was only in place for tax years 2006 and 2007. I actually knocked 400 bucks off my tax bill last year because we installed an efficient door and new hot water tank and furnace. The maximum credit was 500 bucks. But like I said, I don't believe you can get that credit anymore. -- Blue skies. Dan Rossi Carnegie Mellon University. E-Mail: [EMAIL PROTECTED] Tel: (412) 268-9081
