Bay Window


With Select vinyl windows you get the standard features you want and the custom solutions you need. Designed with a deeper, full-line frame, these windows are energy efficient, provide enhanced strength and stability and are virtually maintenance free.


  • Bay windows feature a fixed picture window in the center flanked on the left and right by an operating single hung or casement window
  • Flanking windows are angled at 35 or 45 degrees and project outward from the wall to create a unique space on the interior and a dramatic architectural statement on the exterior

Project Type

New Construction / Remodel - First, you need to determine the size of the New Construction/Remodel window you want to install for your project. Then construct a framed "rough opening" that is sized to accept the window dimensions. Stated simply, the "opening fits the window."

Replacement - For a replacement project, the existing window sashes and balances need to be removed first. Then select a Replacement Window that is sized to fit inside the existing window frame. Stated simply, the "window fits the opening."
