Looking to put Low E 366 with Aluminum windows with thermal break.
I live in Houston Texas and this will be a ICF home with brick.
My understanding this is a great window in Hot Houston.
This should be a good efficient windows?
Any other better windows?
I hate the look of Vinyl plastic and do not like wood maintance.
Thanks!

There are many good fiberglass windows to choose from, especially in the hot and sunny climate. As you are probably looking at hung windows, try considering casements.  Don't forget a good spacer either XL or Super Spacer. Marvin and Milgard will be most prevalent in your area.

However if you want aluminum, try NT Windows they are right in your backyard.

Here's the answer for smart, economic, beautiful windows in Houston: "pultrusion" fiberglass (FG), with more than a 25 year history and now the fastest growing sash/frame material in North America. See AlpenHpp.com - mention that Robert Clarke suggested your inquiry. As emphasized in my earlier posting, Heat Mirror glass in all configurations is available in the sashes and frames of virtually all FG windows.
