[Greenbuilding] [BULK] The beauty of STEEL FRAME WINDOWS.............?????

[Lawrence Lile]

Kathy, 

Forget those guys who say you have to replace your windows - you have a
great idea with the quilts.  Get your parts and pieces from these guys.
And send us pictures when you have one finished.

Okay, I have a question.  I am remodeling a house built in 1940.  Steel
frame casement windows.  Single pane.  Northern California.  COLD in the
winter!  I think the BEAUTY of steel frame windows is that MAGNETS can
stick to them and hold up "hand-made, quilted and batted" insulation
"shades".  What should I stuff them with...............aluminum [foil]
in
the middle or just batting like a nice warm quilt?  Please advise.
Winter
isn't TOO far away.

Thanks.....Kathy Cochran
