Hi ZIns, Oberon offered professional technical details so I will chime in with homeowner experience. Yes, even with Low-E, there will be fading. Depending on the amount and intensity of exposure and the finish, it is a matter of how much and how soon. In a situation where the sun is very mild and light, by the time fading is noticeable, it may also be time to refinish the floor. My guess is the floor is not receiving year-round exposure, true? The sun is stronger and deeper during some time of the year and weaker and less intense at other times, is that so? We have seasonal sun intensity problem too and solve it with a combination of solution. We use rugs to protect several sections of our floor during mid-Spring through late Summer. The rugs are removed to prevent tripping when we have visitors. The rugs are also removed around Autumn when the sun is low and the exposure is much less intense and shortening each day. We have old furniture in one area by our French doors and my wife made knitted coverings to cover the furniture. As necessary, we remove the covering when appropriate. Outside the French doors, we installed retractable awning so that during extremely hot summer days, the awning extends to provide cover without blocking natural light. Our goal is to not use any window treatment because we enjoy natural light and the views. Hope this helps a bit.

Hello Catherine, have you thought of contacting a place like Budget Blinds or 3 day blinds? We have a window that requires a special treatment and I contacted both these companies. Both offer free consultations, their companies offered different solutions, and brought up things I never would have thought of. The cost was more than if I had gone to Ikea and bought some panels, but I am very happy with the end result!

You can do the panels On the slider which can be pulled aside (they can on windows too) for unibstructed view when opened. It’s also acceptable to shutter the windows with panels and then just place panels on slider. I would do three full panels testing the two windows as one large one. Have them shuttered that way as well so it’s not as choppy. The space between the slider and window i would do one double panelto dress both sides. Or you can do a natural woven shade or roman shade on double windows that pulls up and down. Neither of these will give you view unless opened all the way. Maybe if we saw more of the room we could tell you which would best suit the space.

As the room is under construction, perhaps you shouldn't do anything until you live with them for awhile. Personally, I wouldn't cover the doors -- I like as much light as possible -- and anything you installed could interfere with the cabinet just to the right. -- amateur
