Here's a quote: Till 3rd week of July, a vinyl replacement from a quality vinyl window manufacturer, wood grain interior, white exterior, window with a U-factor of .30 or less, SHGC of same or less...your price installed, $450 per opening. If you want the exterior wrapped in a maintenance-free aluminum, that's another $50 per opening...oh yeah....and one signed story...I'll have to get a fresh copy of Lisey's Story...mine has been through the mill. The manufacturer might run a no-extra-charge for triple-pane like they did last year...U-factor of about .25 or less...down around .11 with krypton-gas instead of argon, but the price is about 300% more...they blame it on the auto industry...price of krypton.
