I am trying to find a manufacturer that will make a cottage style window that has a 1/3 x 2/3 split. The closest I have been able to find is a 60 / 40 split , apparently due to the weight of the lower sash and the capability of the balance systems to support it when open. Specs on the windows are 35 1/2" x 71 1/2" with the lower sash tempered. If anyone knows of a high quality replacement window manufacturer that can make a window like this I would really appreciate any info you supply. Thanks
Check with Milgard in your area. They will put the bar set pretty much where you want unless their engineering dept has a reason not to, as to size constraints. Hope this helps.
