Low e is only part of glass performance. SHG solar heat gain is the
rating you need to compare. Some companies make glass just for what
you want. You realy need to do alot of research to find out what is
needed for your area and price it out. Alpen and Hurd are a few
companies that make glass to reduce SHG. Im in the north , in winter
we want SHG so glass for my area is different. There are quite a few
tests done to compare glass, you need to know and use the ratings.

Thanks to all for the input, been sittin at the ,puter gathering data.
Seems Argon gas is the way to go with Low E and solar glass. *Finished
my window measuring just to have an idea and actually have almost 425

Once again, thanks for the tips.- Hide quoted text -

Who has R 10? you are not figuring it out right, you are paying for
energy savings if your sun load is that high. Payback would be much
faster if it keeps the AC from running as much
