Hi Angie, these windows are original from the 1950's home we remodeled. They are direct set glass in wood post and stops. We loved the look also and just rehab'd the frames, changed the color to a cool gray so they disappear from the view. One pane (out of view in this photo) we replaced with sliding door from Fleetwood to create one operable panel and provide access to a new hot tub.

Thanks for asking,

Scott Couture
