I considered those for my patio door, but decided to get these instead and haven't regretted it at all. Love the look when closed and when opened I push them back to have the entire window to see out of.

I have them. I LOVE them. I live in MN and it is amazing how much they keep the cold out on a night like tonight when it's really cold. In the summer they are open virtually all the time. I do not know how to post pictures on here but I can email you a picture directly if you would like. My home email is rclgiese@aol.com Mine are on my sliding doors going from my kitchen to my deck. Everyone who has seen them has asked about them. I mounted my at the ceiling. LOVE that too.

Hi. Could you share the approx. sizes and what you paid for them? I just got a quote for a 189" opening with 11.5" panels for $3,653?! Any guidance would be appreciated. Thx.
