Post up a photo. There are several different grid styles and patterns. One that is becoming very popular in our area is a colonial grid in the top sash only. Gives a nice aesthetic appeal without cluttering the window. Obviously everyone is different but I find a lot of people leave the grids of due to price. This may or may not be the case with your neighbors

I prefer to match the grid style to the prevailing house style, as windows have so much impact on the aesthetic of a house. Our current neighborhood is either traditional or New American - depending on your opinion of either - and a couple of houses have replaced their windows with no grid. IMO it ruined the look of the houses.

I agree and the same thing could be said for colorsI see too many times someone puts a white window in a house that has no business having white windows. Completely ruined the curb appeal

I would not worry about what is trending and go with what you like.

Exactly what toddinmn states........

+1. I don't know of any specific trending per se. I like the less cluttered look myself and it is especially nice if you have a nice backyard or view. Some folks are going with grids in the top sash if they are looking for a different look (I guess bordering on prairie style). Whatever you do, I would go with the default pattern for the manufacturer in this case. They know what looks best in terms of a pattern in the windows.

What is the style of your house? That should be what determines whether or not you put grids in. Now having said that, if you do opt for grids, PLEASE put in simulated divided lights vs those fake looking grids inside the glass, or the flat ones on top of the glass.

No grids more expensive, I guess b/c the hot trend. We kept grids b/c of cost

Thanks for all your comments. We signed a contract today to buy Okna 505 double hung and are continuing the grid pattern in the front and sides and doing the clear glass in the back for a more unobstructed view.
