We have a big skylight (about 10' x 17') that cooks our house in the summertime. We moved in toward the end of the summer last year so just dealt with it. But we have to do something. I investigated the tints, and there are some very good ones out there now that provide UV protection and are not visible -- much improved from the old metallic-looking films of years past. But what I found was that the DIY films you can buy at the big box stores are not of the same quality as those you purchase from pros who also do the install. The pro stuff can be pricy. 3M makes good films, and I can't remember the other big company. For my skylight, I came across a company that makes UV-protection-fabric screens that slip on over the skylight. I can get one of those made for about $700 and the pricing for the film/install was going to be about $2,000. Unfortunately, I don't think that helps you with your vertical surfaces. I like the idea of the panels. If I'm thinking of the same thing, IKEA has them. You have to be able to install a track, and the panels are about 18-24" wide and can be patterned or plain. You may be able to compromise by doing the lower windows and film on the upper wedge-shaped windows.

In my world roller shades of any sort would only be a applied in a bedroom. They are much too utilitarian for other applications. I totally agree on the blinds. They are a NIGHTMARE to clean. I would only have them in a bedroom, grew up in the military where they were EVERYWHERE.. ISH. In the early '90's I had a red accordion blind in a bay in the kitchen. Most of the time it hid under the valance...turned the entire room RED when the afternoon sun hit it. I was young then, still learning......

Are you set on cellular? We just went shopping for new shades and I thought I wanted them, too, but when I looked at them we discovered that they were ALL a kind of paper. For the money, I wanted more. We ended up with roman blinds that can be top down and/or bottom up. I agree that one solid blind seems riskier to me and might not last as long due to stress...

Hi Sarah, Hunter Douglas! Their Designer roller and screen shades, Vignette, Duette, and Solera all come in those widths. There will be fabric restrictions but you should be able to find something you love.
