That is a very informative article. Very interesting. I shall keep that
in mind for my home also.

About this energy efficient windows. I have to say that these windows
really work during summer. I had 2500 sq ft house just 2 miles south
from where I'm at and my electricity bill was about $300 per month.
Now with 4000 sq ft house with these windows, I'm still at $300 per
month, max !!! My old house was built in 1999. I'm sure other factors
helped, like SEER 14 AC (two of them), which I paid extra for. And
these blue tint actually looks pretty good. Sorry, off the subject.
