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

Judges for the 2022 Window + Door awards explained their selection of Aspekt+ 1800 as follows:

This is a solidly built casement window. As the desire to fill larger openings continues to grow, the strength of the product must also; this is a step in the right direction. Utilizing a reinforced inner core capped with uPVC for improved appearance and improved strength gives this product the innovation award. The energy efficiency is fantastic. The Aspekt+ continues the REHAU trend of introducing cutting-edge products. This glass-fiber reinforced vinyl window's ability to simultaneously deliver Passive House U-values, great sound attenuation, high structural ratings and large sizes is exactly what the marketplace increasingly requires.

Commenting on the award, REHAU Marketing Manager Katherine MacNevin said, “We couldn’t have said it better ourselves. We are extremely honored by this recognition from our peers in the window industry. Drawing on our German heritage and North American ingenuity, innovating in the rhelm of high-performance windows and doors is where we excel.”

Working toward its mission to empower architects with information to build better buildings, better cities and a better world, Architizer sponsors their annual A+ Product award program in which a global panel of architects and designers choses the world’s best products in terms of aesthetics, performance and impact.

The 2022 Vision Awards were judged by an independent panel of eight facility executives who chose 30 of 150 product entries for their contribution to the efficient and profitable operations and management of institutional and commercial buildings in the United States.

“We are also proud of the 2022 Architizer A+ Product awards recognition from the A&D community and the 2022 Vision Awards selection from the commercial building market,” said MacNevin. “With the ability to build larger units and offering performance up to stringent Passive House requirements, Aspekt+ is a great choice for designers and developers who are seeking to create a sustainable, enjoyable building.”

“Our products often win awards for their longevity and sustainability because these are values we design into our products from the start,” said Dr. Thomas Troeger, CEO of REHAU Americas. “However, I can’t recall another product that has won three awards in its first year. Congratulations to our Window Solutions engineering team for this valuable innovation.”

Aspekt+ 1800 is a top-of-the-line outswing casement window solution that provides superior thermal comfort, acoustic insulation and structural performance. Offering a modern design aesthetic in a wide range of colors, Aspekt+ 1800 allows fabricators to build units for up to 30% larger openings with long-lasting stability and torsional rigidity. The Aspekt frame is built with REHAU’s proprietary North American PVC formulation combined with a sophisticated multi-chambered design and a proprietary triple-seal technology. The new sash – comprising a UV-resistant PVC outer layer and a glass-fiber reinforced PVC inner core – enables Aspekt+ 1800 to outperform alternative casements. 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, structural NAFS ratings up to CW-PG100 and a U-value down to 0.14.
