Can you post some pictures? It would help with brainstorming. If it was my home I would probably hang a curtain rod that is longer than the base of the triangle and use drapes just like for a rectangular window. But it's impossible to tell if that will work without pics.

You could also try shutters, either triangular shaped and opening to the top or rectangular, again treating the window as a rectangle shape and covering a good bit of wall at the top.

Oops, I guess I should have given more info... they are triangle windows right under a pitched ceiling. So it would even have to be automated! (I'm trying to edit my post to add this extra info and photo but for some reason it won't let)

You have a very interesting dilemma! The location of the room may make your need for covering a non-issue for you. Have you stood in the room in early morning? How bright is it? Those windows are so high, bright morning light might not even reach into the room.

I found this on Houzz. They were manufactured by Blinds.com. Hope this helps and Happy Houzzing!

Does the room need that window ?

I think the only shades you can get for that window will not be operable.

snaggy asks a good question. can you just cover it up with opaque anything while your children are small? in a couple years you wont be able to wake them no matter what.

as for you, i've found that putting the head of the bed under the window makes for the darkest sleep.

Actually, Linda is on to something. Use the highest "darkness" of UV protective window film. (3M makes a line and there are lots of knockoffs). That is secured in place but trimmed just shy of the woodwork and can be removed later with no visible damage to the windows.

So is there another window under there or is it all wall space? Can't tell from your pic what the finished look will be.

If there will be wall space underneath, the only thing I can think of that could be operable would be bottom up shades. You might consider having someone come in and measure rather than an online site.

eta: I don't really know of any places online. You may have to go thru a workroom or designer for specialty shades.

Hunter Douglas can make custom shades for specialty shapes. I would contact a local dealer.

Thanks all. To answer the questions...
- yes those windows need to be there
- the framed space below the triangle that is framed (from the floor up) is a sliding glass door
- I don’t know about a film if it will ruin the aesthetic of the windows
- there are 2 other rooms with triangular windows... those are the kids rooms.
- I will check out the sources listed, thank you v much.

" I can't have my kids waking up with the sun "

LOL! My son would not have woken up with a full-scale open skylight. Most kids sleep like the dead. Sorry if yours don't...that's a bummer.

The film is installed on the insides of your windows and will probably look far more streamlined than any kind of blinds which will have to be drilled into your windows for installation. The 3M kind uses soapy water to install and it is removable.

Bali makes shades for windows of many shapes including triangular. Scroll down to the Specialty Shapes section of this Bali webpage. They can be purchased at blinds.com

@Jerri Blank - did you figure out a solution to this? We have fleetwood Transom (Tringular) also with a pitched roof and a sliding door under it in our master and trying to figure out if we can do some sort of minimal modern blind solution.

@praniti - I didn’t :( the sun isn’t too bad in the morning as we are in a canyon anyway. Sorry I couldn’t be any help
