I love the "sunburst" name and style, but I have always found it difficult to find a window coverings for them.

Barbara Todaro I'm going to guess a pediment.

Buyers call it sundial and fan windows. We agents have learned what they are meaning.

When you only buy a Half Round of drinks for the bar, those left with their glasses empty may burst into tears!

Thanks for the lesson.

I thought a palladium window.  I love them & if I call them pediments no one is going to know what I'm talking about.

I would never have known this one.

That was the signature feature of the '90's.

Aniother name could be expensive to replace.

A fanlight possibly.

I would say arc

Fanlight?  

Arc? 

We call them " features ".

You are just full of knowledge sharing lately! Keep them coming!

Thanks for your knowledge Barbara Todaro learning new terminology is always fun and helps me look like the subject matter expert with buyers. 

Thank you,

Barbara Todaro - thanks for the question - and answer, too. (Stopped by here a bit too late to even Google it....lol!)

Had to check in for the right answer

Of course he does ;)

Very nice, thanks for the lesson.

That is the only name I know of

Thanks for the lesson Barbara Todaro My neighbor installed Sunburst when they remodelled their older home.  Looks wonderful.

I'm going to go with Pediment, but only because I'm two days late to this question apparently.
