We have recently moved into a house with 2 windows like the one in pictures, and I *really* don't like them -

- At the joint(wall meets roof) there isn't any strong structure(eg. wood, stud) you can screw bracket on for a blinds/shades for an inside mount. Also the it's difficult to put any shades on the skylight part of it - although a tranditional skylight has the same problem, but this window is a lot bigger and there isn't any drywall under that to bounce and defuse sunlight.

- It's a rather large window but it cannot be opened.

- It's really ugly to look at it from outside.

we are considering replacing 2 such windows with standard sliding windows, close the roof and cover the drywall ceiling, as part of our remodel project.

Are we looking at a very expensive one? I mean in additional to a standard window replacement?

Also is there a official name for such kind of windows?

Thanks!
