This is an Andersen 400 Series Double Hung window in Low E4, 36 x 60 with custom divided lights in the upper sash. In 2019, with all hardware and screen, was $556 from Home Depot. It's the trim around the window that sets it apart form the normally plain look. The trim is all closed cell PVC, CertainTeed, in this case, but similar to Azek or Royal. Your options may vary. Plus, with COVID, who knows! I have tried to get additional LP Siding form Lowes and was told that LP wont even talk to them until December!
