REHAU Aspekt+ 1800 outswing casement window

REHAU Aspekt+TM 1800 features a strength-enhancing sash in the company’s innovative RAU-FIPRO® glass-fiber reinforced PVC material. The new Aspekt+ 1800 is designed to meet stringent Passive House requirements while addressing the growing residential and commercial demand for larger windows.

Aspekt+ 1800 out-swing casement window provides superior thermal, acoustic and structural performance, and can be built for up to 30% larger openings with long-lasting stability and torsional rigidity in a variety of colors. Using an advanced material along with REHAU co-extruded triple-seal technology limits thermal conduction and ensures a tight frame-to-sash seal with a significantly reduced U-value down to 0.14.

The Aspekt frame is built with REHAU’s proprietary North American PVC formulation using a sophisticated multi-chambered design. The new sash–comprising a UV-resistant PVC outer layer and a glass-fiber reinforced PVC inner core–enables Aspekt+ 1800 to outperform competitors.

With 3 1/4 in, 3 3/8 and 3 1/2 in (83, 86 and 89 mm) frame depths and 1 11/16 in (43 mm) glazing capacity, the system is designed to achieve STC ratings up to 42 dB, OITC 34 and structural NAFS ratings up to CW-PG100. Contributing to an optimal fabrication process and consistent sightlines from fixed to operable units are the system’s capabilities for direct-set glazing and multi-lite configurations within one continuous frame.

RAU-FIPRO provides built-in structural integrity to go larger than standard PVC units without steel inserts, which detracts from thermal performance, and is resilient to North American weather, creating stable profiles that expand and contract 60% less than PVC.
