Shouldn't really matter. You can put grids in the top half if you want.

IMO windows on the front of the house should all match both in style and function so double hung with the grids and the fixed one also with the grids to match all grids only on the top portion BTW get rid of the shutters those windows should not have shutters and then go to work on the landscaping

Hi, Leslie,

You can absolutely do a bay window configuration with fixed window and casements flanking. Take a look at the installation we did on a house here in Texas. All the windows we used on this project were from Andersen and the casements had a piano hinge which allows the windows to open wider than other hinge types allow.

Patricia makes some important points, if you replace the bay windows but the rest of the windows on the front side of the house it may look a little funny if the windows can't be ordered to match the size and spacing of the grids on the windows above. That's definitely something you'll want to bring up with your window retailer, hopefully they can find windows that match but it may not be possible.

As far as grids matching across style, you'll have to keep an eye on that when window shopping. In the video above the grids and frame profiles on the windows all align so unless the windows are open you can't tell at all that they are different styles. Not all window vendors design their windows with that in mind. Take a look at the examples below. Milgard's Trinsic series has good alignment on this slider and across the entire series but the Styleline series doesn't carry the lines across the slider window or any of the other windows in the series.

Thank you Brennan Enterprises. I ended up going with 2 double hungs on the side 2 windows and they have grids to match the top windows. It came out great!
