Thank you - it looks great!

Are these windows 18" wide? We are choosing windows for our kitchen and it would be very helpful to know. Thank you!

They were 30" wide. But when choosing windows you can't just pick an arbitrary width. You choose the width in relation to the spacing between cabinets, and in relation to the other windows on the house and to keep a consistent proportion of muntin arrangement. Note that the upper 4 light sash creates 4 almost perfectly square glass panes - similar in proportion to the large square glass below and the 2 others above. Changing the width, height and muntin pattern could have made those panes into rectangles upright or on their sides. We chose the squares in this case to match the other windows we put in this house and to match the style of the overall house design.

are the windows single hung or double hung? are the screens in the windows?

Those are double hung windows with screens.

No question--I would just like to thank you for explaining what goes into choosing such things as window width, room height, and so on. It's both helpful and interesting, and I want you to know we appreciate it.

What size transom do you have on top? They look larger than the traditional 1/0 transom.

1 foot 5 inches if I remember correctly
