[Greenbuilding] Exterior insulation retrofit

[bill.allen at verizon.net]

All,
Thanks for your comments on this thread.  The one thing no one commented on was the windows.  Do folks have experience with R5 windows?  Can you recommend any mfg's?  I am thinking Marvin Ultimate clad (wood with aluminum cladding on the outside) but they cost an arm and a leg, even more so with triple glazing to reach R5. Alternatives?
Thanks,
Bill
