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."
