This is a small, double pane, window that would work well for a shed, kids play house, or perhaps a tree house. It is 26" tall, 16.5" wide (flange edge to flange edge). The main body of the window is 15.75" wide. It is designed for standard 2x4 construction hence it is roughly 4" thick. Color is white. Frame is probably vinyl or PVC, I don't really know for sure.
