SCHÜCO FWS 35 / 50 / 60 Curtain Wall System
Schüco FWS 35 / 50 / 60 curtain wall systems set new standards in fabrication and energy efficiency. An extremely slender façade design, featuring almost frameless transparency that meets the most demanding requirements, requires more than just large glass areas. A first-class visual appearance and an ideal view of the outside meet the highest requirements in high-end residential and commercial construction.
Aluminum mullion and transom curtain wall systems that cover the full range from ultra-slim Panorama Design façades to high-performance building envelopes. FWS 35 PD utilizes 35 mm face widths with system-integrated all-glass corners to create almost frameless glass façades, ideal for high-end residential and low-rise commercial projects. FWS 50 is a 50 mm curtain wall family with a wide depth range, heavy glass capacity, and multiple insulation levels, including the FWS 50.SI Super Insulated variant that can meet passive house requirements. FWS 60 builds on the same design principles with a 60 mm face width and deeper profile options, including FWS 60.SI variants that achieve passive house certified performance while accommodating very heavy, double- or triple-glazed units. For Eagle View Glass projects in British Columbia, the three systems enable façades and large window walls to be tailored to different exposure levels, energy targets, and design priorities, all while staying within the Schüco FWS platform.
An innovative system for attaching to the building structure provides reliable ventilation and drainage of the façade in the attachment area, allowing for extremely efficient installation close to the ground.
Notable Features
-
FWS 35 is well suited to low rise façade areas where visual lightness and high transparency are priorities. Typical uses in British Columbia include ground floor feature façades on custom homes, double height living spaces, boutique retail frontages and near grade glazing on high end residential or hospitality projects. In these locations the system can create almost frameless glass corners and large fixed panels while delivering the insulation levels needed for coastal and interior climates.
-
FWS 50 is a practical choice for larger curtain wall areas on multi family buildings, commercial façades, institutional projects and tall glazed stair or lobby volumes across Metro Vancouver and the rest of the province. Its depth range and heavy glass capacity help meet structural requirements on taller screens, while SI variants can support projects that target low energy consumption or advanced green building certifications.
-
FWS 60 is a strong option when spans increase, exposure is higher or performance targets are more demanding. Examples include tower podiums, taller multi storey glazed elevations, office or mixed use façades in exposed coastal locations and projects that aim for passive house or similar high performance standards. On one project Eagle View Glass can use FWS 35 PD for selected feature zones, FWS 50 for standard façade areas and FWS 60 where extra depth and capacity are needed, keeping a consistent Schüco language while matching performance to each part of the building envelope.
Recommended Applications
-
FWS 35 focuses on maximum transparency. Narrow 35 mm sightlines and system integrated all glass corners allow façades that read almost entirely as glass, with no visible vertical mullion at the corner. The system is engineered for high thermal insulation, weather protection and structural capacity despite the fine profiles, making it suitable for feature areas of luxury homes and representative commercial frontages. Prefabricated components and an optimized fixing system for pressure plates support efficient fabrication and installation, which helps maintain quality on complex glazing layouts.
-
FWS 50 is a broader platform that balances design flexibility with performance and constructability. Architects can choose from different pressure plates and cover caps, including flat, sculpted and stainless steel options, to fine tune the façade expression while keeping the 50 mm grid. System optimised details simplify the integration of sun shading brackets, safety barriers and cable management for powered elements. The FWS 50.SI Super Insulated variant combines this flexibility with high insulation levels and has received Cradle to Cradle Certified Silver recognition, which aligns with sustainability goals on modern projects.
-
FWS 60 extends the family for projects that need a deeper façade zone and higher performance. The 60 mm face width keeps a clean, consistent grid while larger profile depths and optimised insulating strips help achieve very low U values with double or triple glazing. System glazing supports and integrated spandrel safety solutions make it easier to handle heavy units and floor to ceiling openings without additional visible steelwork, which is important on taller multi family and commercial façades. Green options within the FWS 60.SI range also use materials with renewable content for selected components, supporting advanced sustainability targets.
Key Specs
-
FWS 35: nominal face width around 35 mm for mullions and transoms, creating a very light appearance.
FWS 50: nominal face width 50 mm, with profile depths typically ranging from about 50 mm up to 250 mm to meet structural and insulation requirements.
FWS 60: nominal face width 60 mm, with a comparable depth range to carry taller spans, larger glass units and higher insulation build ups where required.
-
FWS 35 PD.HI and FWS 35 PD.SI offer high insulation levels, with frame Uf values in the approximate range of 1.0 to 1.3 W/(m²K) and passive house certified variants. 
FWS 50.SI Super Insulated versions use enhanced thermal breaks and insulating foams to reach passive house certification for suitable configurations.
FWS 60.HI and FWS 60.SI variants add deeper profiles and advanced insulation zones, with selected FWS 60.SI configurations achieving passive house level Ucw values on appropriate glass build ups.
-
FWS 35 is designed to carry glass panes up to around 400 kg, which supports large insulated units in high transparency façades.
FWS 50 systems can accommodate very heavy units, with glass loads up to roughly 910 to 1080 kg depending on configuration and project design.
FWS 60 further supports heavy insulated glass and spandrel assemblies, with system glazing supports and carrier profiles tuned for large format double and triple glazed units on taller or more exposed façades.
-
These systems support double and triple insulating glass in various build-ups, with typical pane thicknesses in the 40–50 mm range on passive house variants. This allows high-performance glass combinations for energy efficiency, solar control, and acoustic reduction.
-
FWS 35 PD and FWS 35 PD.HI is tested for high levels of air and water tightness suitable for exposed façades and low-rise applications.
FWS 50 systems typically reach air permeability classification AE, watertightness up to RE 1200, and wind load resistance in the range of 2–3 kN/m², with acoustic ratings up to about Rw 48 dB on suitable glass packages.
FWS 60 systems are engineered for comparable or higher levels of air and water tightness with additional depth and glass capacity, which supports stronger structural performance on taller screens and high exposure locations.
-
All three lines offer tested burglar resistance, with options up to resistance class RC2 on FWS 35 PD and up to RC2 and RC3 on FWS 50 and FWS 60 in specific configurations. FWS 50 and FWS 60 systems also support profile integrated spandrel safety barriers for floor to ceiling openings.
-
FWS 35 PD is part of the Schüco Panorama Design concept and can integrate sliding systems such as ASS 77 PD for flush transitions at façade doors. FWS 50 and FWS 60 are designed to accept a wide range of Schüco insert units, including windows, doors and sliding elements, and offer system accessories for sun shading, cable routing and electrical integration.
