Schüco AS FD 75/90 (Bi-Fold Door System)
The Schüco AS FD 75/90.HI is an innovative folding sliding door system (bi-fold door) that allows entire glass walls to fold away, creating expansive openings to the outdoors. This system is available in two thermal variants – 75 mm depth and 90 mm depth (HI insulation) – all under one unified platform. With extremely slim face widths (as narrow as ~90 mm per panel frame) and flush-fitted frames, the AS FD system achieves a surprisingly transparent look for a bi-fold door. When closed, it presents a sleek glass facade; when open, the panels stack neatly to connect indoor and outdoor spaces seamlessly. Despite the large openings it can create, the system maintains excellent thermal insulation (the 90.HI version being highly insulated for energy efficiency) and reliable weather performance. It’s engineered for flexibility – panels can fold either inward or outward, to one side or split to both sides, giving architects and homeowners maximum freedom in design and operation. The Schüco AS FD 75/90.HI adds a dynamic, modern element to homes and businesses, essentially acting as a moving glass wall that can disappear on demand.
Notable Features
Massive openings – the AS FD system can effectively remove an entire wall, perfect for indoor-outdoor living and entertaining. Even when closed, it provides a glass facade effect with slim frames, enhancing natural light and views. The platform concept means both 75 mm and 90 mm versions share most components, offering consistency and ease of customization; the only difference is the insulation level, with the 90.HI is geared for higher energy efficiency or colder climates. Schüco’s engineering ensures that, despite multiple moving panels, the system remains secure and weathertight – featuring multi-point locks, tamper-resistant hardware, and an advanced sealing concept for air/water tightness. Aesthetically, the new profile design hides most hinges and joints, giving a clean, flat appearance when the door is closed (no bulky protrusions). This folding door earned design awards for combining flexibility with performance.
Recommended Applications
A top choice for luxury residences in British Columbia desiring a wow factor – for example, opening up living rooms to patio and pool areas or connecting a kitchen to an outdoor deck. It’s also popular in restaurants, cafés, or resort properties where large openings create an al fresco atmosphere on demand. Use it for sunrooms or solariums to fully open them in summer while still having a sealed enclosure in winter. The AS FD 75/90.HI’s high insulation makes it viable for year-round use in Vancouver’s climate and colder regions – homeowners can enjoy open-air living in nice weather and still have a cozy, draft-free space when closed. It’s equally suitable for commercial showrooms or event spaces, where entire walls can be opened for access or aesthetic appeal.
Key Specs
-
Multiple panels (e.g., 3+3, 5+0, etc.) can be linked; panels fold either inward or outward. An optional integrated swing door (traffic door) can be included for quick access without requiring the folding of all panels.
-
Slim profiles – about 90 mm face width for each panel frame, yielding a clean all-glass look when closed. When open, the stacked panels fold compactly with minimal visible frame.
-
Vent heights up to 3000 mm for AS FD 75 and up to 3500 mm for AS FD 90.HI; panel width ~ up to 1.2–1.5 m each. Max weight ~150 kg per panel (allowing use of double or triple glazing).
-
AS FD 90.HI offers superior insulation, meeting stringent energy requirements (it features an expanded insulation zone compared to the 75 version). U-values can approach those of fixed windows for the 90 mm system (specific performance depends on glazing). The 75 mm version is also fully thermally broken and suitable for standard energy-efficient builds.
-
Dual continuous gaskets ensure strong weathertightness – improved seals provide excellent resistance to rain and air infiltration for all configurations. The system achieves up to RC2 burglar resistance, with multi-point locking on folding panels for security. Three threshold options are available, including a flush low threshold for easy wheelchair access while still maintaining good sealing.
-
Smooth, quiet operation is achieved via robust stainless steel running tracks and rollers. Magnetic stops hold panels in place when folded open, preventing movement. The design features cleverly concealed hinges and flush bolts, ensuring the hardware does not detract from the overall aesthetic.

-
A comprehensive selection of opening and locking types makes individual designs possible with maximum planning freedom.
3 different threshold types, including a flat threshold with great rollover capacity, make the system adaptable to many installation situations.
An optional side-hung door enables quick passage, while an integrated magnetic retaining catch ensures secure opening and closing of the folding sliding unit.
The system now offers a higher level of security, meeting burglar resistance class RC 2.
The improved sealing concept with two continuous gasket levels offers greater watertightness and air permeability values for all opening types.
