Two Precision-Engineered Schüco Door Systems
Zyle Fenster supplies and installs two Schüco aluminium door systems: the ASS 70FD bi-fold door and the high-insulation ASS 70HI sliding door. Developed in Germany and trusted globally, each Schüco door system combines exceptional quality, wide-ranging design options, and durability – delivering aluminium doors that perform as well as they look.
Schüco ASS 70FD: Aluminium Bi-Fold Door
The Schüco ASS 70FD is a precision-engineered aluminium bi-fold door system that brings together smooth operation, excellent weather resistance, and high transparency. Its rounded profile corners give it a refined, contemporary appearance, while units can be configured to open in multiple directions – offering a wide range of design options for both residential and commercial buildings.
Built to the exacting standards of German engineering, the ASS 70FD delivers consistent performance and durability across its lifespan. With strong thermal insulation as standard and robust security features integrated into the system, it is a stylish and dependable choice for architects and homeowners seeking Schüco doors that meet the demands of modern architectural design.
Schüco ASS 70HI: High-Insulation Aluminium Sliding Door
The Schüco ASS 70HI is a high-insulation aluminium sliding door system designed for high-end residential homes and commercial buildings where performance, aesthetics, and scale matter. With some of the slimmest sightlines and largest panel sizes available in any aluminium door system on the UK market, it creates a striking connection between inside and outside spaces.
The ASS 70HI combines excellent thermal insulation with smooth, near-effortless operation – even across large glass panels. As a premium Schüco aluminium door, it offers exceptional quality and long-term durability, making it a reliable specification for architects, developers, and self-builders who require aluminium sliding systems of the very highest standard.
