This one comes straight from the manufacturer. Pella modeled its Architect Series aluminum-clad wood double-hung window at 31 in wide by 55 in high, and notes that the real window is built to order in larger sizes, so you can resize the drawing to suit.
Because it’s a manufacturer model, it’s a good choice when a project specifies Pella or when you want a window with realistic sash and frame proportions.
This model was made by Pella Windows and Doors and is shared on3D Warehouse, where you can download it under 3D Warehouse's terms. We don't host the file; the 3D view and thumbnail load from 3D Warehouse. If this is your model and you'd like it changed or removed, tell us.
