Two Schüco Window Systems for High-Performance Buildings
Zyle Fenster supplies and installs two Schüco aluminium window systems: the high-insulation AWS 70HI and the Passivhaus-certified AWS 90 SL+. Both systems are the product of German engineering at its most refined – offering narrow frame sightlines, excellent thermal insulation, smooth operation, and a wide range of design options for residential and commercial buildings across Ireland.
Schüco AWS 70HI: High-Insulation Aluminium Window System
The Schüco AWS 70HI is a high-quality aluminium window system that brings together a wide range of design options, strong energy efficiency, and reliable weather resistance in a single, highly adaptable platform. Its slim profiles and clean lines give it an unmistakeable style that works equally well in contemporary new builds and refurbishment projects – for both residential and commercial buildings.
For architects seeking a Schüco window system that delivers lifetime value without sacrificing aesthetic appeal, the AWS 70HI is a trusted and proven choice. It supports double and triple glazing, is available across a broad range of finishes, and meets the highest standards of thermal performance expected from a premium German-engineered aluminium window system.
Schüco AWS 90 SL+: Passivhaus Aluminium Window System
The Schüco AWS 90 SL+ is a Passivhaus-certified aluminium window system designed for architects and specifiers working to passive house standards. Its narrow profiles and concealed ventilation allow for harmonious aluminium block window solutions in single and double-vent configurations – combining excellent thermal insulation with a refined, minimal appearance that supports the most demanding energy efficiency targets.
Developed in Germany and built to the highest standards, the AWS 90 SL+ represents the upper tier of the Schüco aluminium window system range. It is the ideal specification for your next project where passive house standards, triple glazing performance, and timeless design all need to be delivered within the same system – without compromise.

Our conservation project required slim glazing without compromising performance, and Zyle Fenster recommended their vacuum glazed timber sash windows.
The result is outstanding. The traditional appearance has been preserved while the improvement in warmth and noise reduction is remarkable. You simply wouldn’t know they contain such advanced technology.
Excellent communication, excellent installation and an exceptional product.
