Overview

3 1/4” Architectural Grade Fixed, Projected, and Casement Window System This window system was designed specifically for the historical replication of steel sash windows. Care was taken to keep sightlines in line with typical National Park Service historical preservation profiles. The 3100i uses a 24mm polyamide crimped in place structural thermal barrier in lieu of the traditional two-part poured and debridged system. This allows for an increase in thermal performance while retaining the economy of its predecessor. The 3100i series is tested to AAMA Architectural Class (AW) specifications, and carries NFRC 100, 200, and 500 certification. The frame and operating sash depths are both 3 1/4”. The 3100i series utilizes an interchangeable exterior grid system that allows for multiple exterior profiles while using the same basic frame sections (ie. bevels, coved, Ogee etc.). Between glass, and interior applied muntins are also available. Perimeter receptor systems and a full range of panning and snap trims are also available. Main frame construction is mortise and tenon joinery with dual integral screw races. Operable sash use mechanically joined, angle reinforced, mitered corner construction. Removeable interior glass stops accommodate glazing infill options from 1” thru 1 1/2”.
