Overview

4” Architectural Grade Fixed (2141Xpt) And Vertical Sliding (Single Hung) Window System Traditionally, using a vertically hung operable window system meant that thermal performance was being sacrificed. So it was no surprise when the adoption of stricter commercial energy codes eliminated traditional hung window systems as an option in many climate zones. In response to this, a dramatically more thermally efficient vertically hung window system was needed. The innovative Manko 3141xpt series window system was developed. The 3141xpt 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 hung windows. The 3141xpt series is structurally tested as per AAMA Architectural Class (AW) testing, and NFRC 100, 200, and 500 thermal certification. The frame is 4” overall. All operable sash are dual weather stripped. Integral pull handles with spring loaded snap locks are standard. Cam action sweep locks are available. Balances are available in heavy duty spiral balnces, or as class 5 balances. Perimeter receptor systems and a full range of panning and snap trims are also available.
