Retrofitting masonry openings or historic structures in order to install energy efficient windows can be time consuming and costly. Our solution? The Harvey aluminum panning system, designed to fit our vinyl windows perfectly.
Harvey’s panning system is designed for window replacement applications over existing wood or steel frames, allowing for a clean, tight window installation while leaving the existing building intact. The panning covers the perimeter of the opening without disturbing the casing and frames, and provides a stop to install the window into.
Our design utilizes a sloped sill with a common part for the head/jamb and is engineered using heavy extruded aluminum parts. This highly compatible system installs into the window opening first, followed by the window (replacement style).
