Replacement Pocket vs. Full-Frame Windows

Replacement windows are available as pocket or full-frame windows and are designed so that the installer does not have to remove any exterior materials of a home including the siding and exterior cladding. Pocket replacement windows are installed into a pre-existing window frame from the inside of the home whereas full-frame replacement windows completely replace the window frame and will adequately flash the opening.
