As far as reinforcements are concerned, it seems as if they must have
something because they have a demo where they drive a car across the
windows. I know, a lot of "show" for a consumer like me who doesn't
have a lot of knowledge, but they must be pretty tough. That, along
with guaranteed to not be out of square forever (labor included in the
lifetime warranty, fully transferrable), makes me think they are
extremely rigid. Please shoot holes in my thinking though, that's what
I need someone to do.

If the extrusion is not flimsy to start with, there is no need for
reinforcements. Usually these are aluminum or steel, transfer heat and
cold, make the windows heavy and cover up substandard materials.


The warranty is what really impressed me. Full
lifetime warranty, against breakage even. Warranty includes parts and
labor. The only risk there seems like it's if the company would go out
of business or be purchased.
That is right. There is a company called champion who has been in
business for 50+ years. and offer the same warranty.



Not sure what the balances are? Can anyone educate me?
Think about balances inthe windows like the springs on your garage
door. They neutralize the weight of the window to make them easier to
lift.


They do have vent locks. (seen it on a demo window)

They do have a screen track system. (again, demo window)

Can you explain why the mention of miracle glass is a red flag? Don't
know a lot about this and am looking for anything I can.

Miracle glass is just a symptom of "hype" which is geared to make you
buy emotionally rather than rationally. Sometimes the "miracle" is
exagerated. Anfd the glass will not make up for a poorly constructed
window.

For 3rd party comparisons of the whole window, go to http://nfrc.org/
and choose the option on the lowest left (directory of certified
manufacturers.) Look up your company on the list of manufacturers ans
concentrate on the U-value of the window. The lower the U-value, the
more energy-efficient the window is. U-value even takes air leakage
and frame insulation values into effect.

It's the only objective comparison of product that exists.
