Inspired Materials :: Steel Frame Windows

As I sit in my Boston loft, looking out the double hung energy efficient windows, all I can think at the moment is "How lucky are people in warm climes that can use single pane steel frame windows!"

I think my next home is going to need some steel frame elements- maybe a room divider, a shower stall, cabinet doors...  I do think a great way to cheat this look is to use true divided light windows and paint the sashes and frame black...  Until then, I'll try and appreciate the energy efficiency of my current windows.  Cheers.
