Window Panning System

Harvey’s window panning system is designed for window replacement applications over existing wood or steel frames. Ideal for the renovation of stone and masonry buildings as well as historic structures, it allows for a clean, tight window installation while leaving the existing building intact. The panning covers the perimeter of the existing opening without disturbing the existing casing and frames and provides a stop to install the window into. Harvey’s window panning system integrates seamlessly with the window giving installers an efficient solution, while at the same time, providing a polished design for building owners.
