We have these drapes over the patio door in our den which has very bright southern exposure. They have been up for several weeks now and we are very satisified with the quality and performance. They do a very nice job of blocking the light when it gets too bright in the afternoon hours. We were pleased that these drapes did not have the white thermal backing and give a much more appealing look from outside as well. More color selections would be a plus, but we could not be happier with this purchase.
