This is a great forum; I've learned a lot, however, it seems some of the lesser known, "better" brands are only regionally sold. I'm in South Central U.S. and would love to be able to make an intelligent decision on replacement windows. We've had a stream of sales professionals in our home and are totally confused. I'm begrudgingly replacing original wood windows on front of the house. The picture window is a huge 6' X 8' with individual panes. 4 across and 3 down. I would really like to have some opinions on an energy efficient, nice looking window that faces West. We've had 47 days of above 100 degree temps and the sun is baking us. ANY recommendations from South Central pros would be very helpful. My hubby is tired of me changing my mind.
