We own a turn of the century triple decker and are considering putting in over 50 replacement windows to save energy and remove lead. We've heard conflicing claims about how much energy new high performance windows will save, numbers as high as 30% to as low as "next to nothing." Our 3900 sq ft dwelling is uninsulated except for the 1" foam board under the vinyl siding. Our windows are or will be in good condition and have storm windows over them. Also .... can you recommend 3 manufacturers?

if your old windows are in good shape and don't have air sailing past them into the house, then the only good part is to get rid of the lead paint. but there are paint products for sealing in the lead paint...

a window that is energy effcient is about r4. your windows have the the wind break with the storm windows,and your walls now with the styrofoam are about r5.

if you don't have insulation blown into your walls, then it may not be a good use of the money to replace all the windows.

Thanks for the information. I've repaired 1/3 of the windows thus far and can repair the rest. I also was introduced to a great V-seal product by an energy consultant so yes ... along with our storms our windows will one day be well sealed without breaking the bank.

I've been told however that radiation of heat through normal glass along with low R factors that create convective currents (the cold air that "falls off" of windows) are significant with old windows. Question: Do you know what the R factor is for a well sealed window with two panes of ordinary glass? Do you know of any way to quantify the heat that is radiated through the glass from within a warm house? Curious landlords want to know.
