You should check out Alpen windows in Boulder, Co. I think they're
better even than Thermotech:

The only window that has been proven to be the worlds most energy
efficient is by http://www.thermotechfiberglass.com/index.htm

They are far superior then any thing mfd that I know of.

Also check out their doors, They have a far superior three lock system
for secure & tight closing against the weather stripping.

Greetings:

I'm an owner/builder (once professional furniture builder), working on a
renovation which is soon to involve complete replacement of substantial
exterior wall.  In the walls I've been preserving, I've installed Marvin
Integrity windows and added two inches of foil-faced foam to the
exterior

(2x4 with fiberglass batts) walls.  In the new walls, I'm trying to
decide whether to invest in higher R than a standard 6" wall, with
either cotton batts or blown-in cellulose, again with Integrity glazing.
I've considered either thicker, double-studded walls, or a layer of foam
inside or out.  The builder who will be doing this phase has proposed
that I'd be better advised to upgrade the windows than go beyond the
standard 6"

wall--that essentially, the windows will be the weakest link in a pretty
good envelope, at that point.  The new walls will constitute about half
of the exterior surface of the house, with the remainder being the wall
assembly I described above.  Assuming an R-40 roof, would anyone care to
offer advice on this?  If the windows are the weak link, what would be a
reasonable step up?
