Overview
4527i Series Project In-Out Casement Aluminum Window
4.5″ ARCHITECTURAL GRADE Fixed, Projected and Casement Window System
The need for a more thermally efficient window with a 4 ½” deep monumental profile led to the development of the Manko 4527i series window system.
The 4527i uses a 24mm polyamide crimped in place structural thermal barrier in lieu of the traditional two-part poured and debridged system. Operable sash sections remain at the shallower 2 ¾” depth. This combination allows for the desired increase in thermal performance, the desired monumental depth profile, but retains the economy of the 2 ¾” operable vents while avoiding the hinging and locking issues inherent with a 4 ½” operable sash.
The 4527i series carries AAMA Architectural Class (AW), and NFRC 100, 200, and 500 certification. Perimeter receptor systems and a full range of panning and snap trims are also available. The flush sash design and dual weathering minimizes air infiltration. Structural wall areas are .125” thick. Main frame construction is mortise and tenon joinery with dual integral screw races. Operable sash use mechanically joined, angle reinforced, mitered corner construction. Interchangeable interior glass stops accommodate glazing infill options from ¼” thru 2”.
