Flushglaze 4500 satisfies an ever-increasing need to integrate architectural window systems with Designwall™ 2000H and 4000H panel jointery. The 4 ½" deep system is ideal for continuous run fixed "strip" windows that are flush with the plane of the panels. The system (not included) installed by a glass and glazing operator, is very appealing in both aesthetics and function and is well suited for low to mid-rise construction. The individual frames can be either shop or field assembled and connect together using a unique "snap-lock" feature. These frames are anchored to the structure at the head and sill using concealed fasteners and provide for safe cost effective inside glazing. The glass and glazing is performed as a subsequent operation by a qualified glass technician. The head and sill receptor extrusions precisely mate with panel jointery and naturally create a positive water barrier without internal entrapment or a complicated array of intricate components. Simplicity is the beauty of this system as well as the basis of function. The basic window framing component profiles have been field proven through years of solid successful performance.
