I have a large expanse of windows facing afternoon west sun. The product worked just as expected, filtering the sun and blocking the heat into the room.

Best fabric I have purchased, beware knock offs from volume marketing companies. Great warranty and sheds water when installed with proper pitch.

Excellent product. Really cools our deck down in the California sun. You can feel the difference as soon as you get in its shade.With the uv protection, I am looking forward to the space during the summer months. We have lots of leftover fabric so we will be trying some of their other applications as well.

[This review was collected as part of a promotion.] An interesting thing happened almost immediately after we put this fabric on top of our pergola. The temperature dropped significantly and our Husky decided that particular spot of shade is a good place to shelter from the heat .think it looks pretty good and was easy to use.
