You need solar shades if you want to control heat and UV rays and still keep the view and IMO mounted above the transom

Fyi, your patio door handle should be on the left so it slides to the right.

M Riz - are you able to post a photo - I was also looking at those but could not find a photo of what these look like closed.

Patricia - thank you - our main concern is just blocking the sun for that 60-90 min time period around dinner time.

The door is existing and we did not have it in the budget to replace them. We will do that eventually.

Window films come in various degrees of light blocking abilities, but they're not going to be sufficient to block the sun shining in at a low angle before sunset. If you don't mind blocking the transom you could hang a roman shade over it. When it's open it would have the effect of a valance. Or do what you had suggested. Sliders are so hard to cover elegantly.

These are inside mount, blackout. They come in a ton of colors and light filtration levels. They stack to either side and the stack at about 6” i cant get a good pic lol

Mounting above the transom, def. However, any kind of fascia/cassette, and roller mechanism is gonna stick out. I'm concerned about that cabinet door being able to open fully. If that's not a concern, check out this phot of fascia above an event space door.

Thank you Gordon! I actually don’t mind that look and regarding that cabinet - we actually will most likely not even use it due to its location and height.

That is my only concern. When there is space, an inside mounted fascia practically disappears!

How much depth for the roller and cassette/fascia would you say?

And does adding motorization add to the depth?

Sorry last question - mounted above the transom on the casing or on the wall?

It depends. Our Fascia has two sizes 3 inch and 4 inch in depth.
