Not a pro. I can’t help you with your question, but why are you adding casement windows if your existing windows are double hung? The windows will no longer be uniform.

Thank you. Kolbe does make a wood casement pushout with brass hardware. BUT, the sash is wider on the casement pushout than on the crank. So the only way to match the thin sash profile to my existing window is to go with Kolbe crank and I want push out. Do you know of anyone else who makes low profile wood casement windows? Custom is not an option due to price (almost double), lead time and lack of warranty.

The first thing I would do is replace the single paned windows then just do them all to match IMO double paned windows are best even where it is not needed for winter it helps keep out heat too.

Look at Marvin, Loewen, or maybe Lepage if in your area. Maybe they do.

Marvin makes a push-out casement in several of their lines. And yes, all wood is available.

Thank you! It would be SO great if I could replace all of my windows but this renovation/addition is costing a fortune. So I am trying to complement what I have in hopes that I can replace in the future. Marvin is too beefy - i'm looking for a streamline casement with a 1 3/4" wide sash. I looked at LePage, which I have not heard of, and I think they might have what I need, but I don't think are in my area which is Atlanta. I have tried to contact them anyway just in case! There is a Loewen rep in my area. I'll check there as well!
