I got the stuff at Home Depot. It is called Gila Designer Window Film and comes in two or three colors, I chose Neutral Bronze. Yeah, it would keep the sun from warming the house in the winter but our air conditioning season is 10 or 11 months long so the pay back is better for that reason. I only put it on the west facing windows. The east windows are shadowed by trees and another house. Very little south sunshine gets in in the summer but does come through a patio door in the window and warms the house somewhat. That is just a narrow beam about big enough for our little dog to snooze in so I just leave that big glass area alone. It does keep carpet and furniture from fading and I don't particularly want the direct sun on either our oriental rugs or the paintings on the wall.
