update to these

If you have the old vertical blinds on your sliding door. Time to get this curtain. The visual appeal. The ease of opening and closing. I should of switched years ago. I installed on a 1" rod and it looks great. Well made, it blocks the heat and the light that pours in from the deck. Just a great product. Do yourself a favor and get rid of those 1980 blinds that never close right. That usually has a couple blinds that are twisted the wrong way and make that annoying sound Everytime the wind blows.

Beautiful and efficient heat blocker

Lovely curtains that exceeded my expectations. They serve as an efficient blocker of the sun's heat from my patio door and prevent the inside temperature from being affected. I highly recommend them.

I wanted a blackout curtain for my sliding door in my hallway overlooking a deck. It's perfect! It's pretty and has a rod to close the curtain with, amazing!
