Overview

4 1/2” Historical Offset Fixed Window System

Traditionally using a horizontal sliding window system meant that thermal performance was being sacrificed. So it was no surprise when the adoption of stricter commercial energy codes eliminated traditional horizontal sliders as an option in many climate zones. In response to this, a dramatically more thermally efficient horizontal sliding window system was needed. The innovative Manko 3450i series window system was developed. The 3450i uses polyamide crimped in place structural thermal barriers in lieu of the traditional two-part poured and debridged system. Framing is further thermally enhanced by using strategically placed, non-structural, convection and radiation barriers. This combination allowed for an increase in thermal performance to levels not previously attained in Architectural grade sliding windows. The 3450i series has been tested to AAMA Architectural Window (AW) standards, and carries NFRC 100, 200, and 500 certification. The frame is 3 1/2” overall. All operable sash are dual weather stripped. Integral pull handles with spring loaded snap locks are standard. Cam action sweep locks are available. Rollers are stainless steel. Perimeter receptor systems and a full range of panning and snap trims are also available.
