About the Schüco FWS 50 system
🏅 FWS — Fassade mit Pfosten-Riegel-Konstruktion (mullion-transom facade) · narrow-sightline base system · Passive House Institute certified (SI version) · Cradle to Cradle Certified (Silver) · Germany

Schüco FWS 50 is a base mullion-transom aluminium curtain wall facade system from the German manufacturer Schüco International KG, with a 50 mm sightline on both the outside and inside of the building. A narrow sightline combined with a wide range of load-bearing mullions and transoms makes the system one of the most sought-after solutions for prestige facades in the residential and commercial premium segment.

A graduated range of mullion and transom depths (from 50 to 250 mm) allows the configuration to be matched to the specific structural requirements of a project while keeping a uniform, narrow 50 mm sightline. A safety-barrier solution integrated into the profile for floor-to-ceiling openings and low parapets delivers a minimalist, seamless facade appearance.

Schüco AWS window elements (including the large-format AWS 114 platform), Schüco ADS door systems and Schüco ASS sliding systems, as well as concealed Schüco TipTronic drives, can all be integrated into a Schüco FWS 50 facade. The FWS 50.SI version has been awarded Cradle to Cradle Certified status by the independent institute C2CPII together with EPEA (Hamburg).

* The Uf value depends on the system version: FWS 50 (base), FWS 50.HI (enhanced thermal insulation, Uf up to 0.88 W/m²K), or FWS 50.SI (Super Insulation, Passive House certified, Uf up to 0.70 W/m²K). Exact thermal and structural figures depend on the infill configuration and mullion/transom depth.
FWS 50 system versions

The FWS 50 system is available in several versions with different levels of thermal insulation — all keep the narrow 50 mm sightline, allowing a solution to be matched to a project's climate and energy-efficiency requirements.

FWS 50
Base version

Uf value from 2.5 W/m²K. A versatile solution for prestige facades without elevated energy-efficiency requirements.

FWS 50.HI
Enhanced insulation

Uf value down to 0.88 W/m²K thanks to improved insulating-insert technology.

Uf value down to 0.70 W/m²K, Passive House Institute certified and Cradle to Cradle Certified (Silver).

Advantages of Schüco FWS 50
Narrow sightline

A 50 mm sightline outside and inside — one of the narrowest solutions among base mullion-transom systems.

Maximum flexibility

A graduated range of mullion depths (50–250 mm) and transoms allows the configuration to be matched to any project's structural requirements.

Passive-house level

In the .SI version, the Uf value reaches 0.70 W/m²K while keeping the narrow 50 mm sightline.

Burglar resistance up to RC3 / FB4

Tested burglar- and ballistic-resistant solutions, plus a safety-barrier solution integrated into the profile.

Window and door integration

Compatible with Schüco AWS window elements (including AWS 114), Schüco ADS door systems and Schüco ASS sliding systems.

Concealed cable routing

Dedicated E-mullions and E-transoms are available for concealed electrical cable routing inside the facade construction.

Large-format glazing

Maximum weight of a single infill element — up to 910 kg, allowing the system to be used with large glazing units.

Sustainability

The FWS 50.SI version has been awarded Cradle to Cradle Certified status (Silver) by the institute C2CPII together with EPEA (Hamburg).

Wide choice of finishes

A broad range of pressure plates and cover caps, including a stainless-steel-effect finish.

Where Schüco FWS 50 is used
Schüco FWS 50 is a solution for prestige facades and roof lights in the premium residential and commercial segment: office and administrative buildings, hotels, high-end residences, and educational and healthcare facilities. The narrow 50 mm profile emphasises the architectural lightness of the construction, while a safety-barrier solution integrated into the profile allows floor-to-ceiling openings to be built without breaking the facade's continuous sightline. The ability to integrate Schüco windows, doors and sliding systems makes FWS 50 a solution for both new-build and renovation of existing buildings.

Schüco FWS 50 — in-depth overview

Schüco FWS 50 is a base mullion-transom aluminium curtain wall facade system from the German manufacturer Schüco International KG, developed as a narrow-sightline solution for prestige facades and roof lights in premium residential and commercial construction. The sightline is 50 mm on both the outside and inside of the building, while a graduated range of mullion depths — from 50 to 250 mm — allows the configuration to be matched to a project's specific structural requirements.

The system's key feature is the combination of a narrow sightline with a safety-barrier solution built into the construction: the required safety-barrier load for floor-to-ceiling openings and low parapets is achieved without breaking the profile's continuous line, giving the facade a minimalist, seamless appearance.

The system is available in several versions with different levels of thermal insulation: the base FWS 50 with a Uf value from 2.5 W/m²K, FWS 50.HI with enhanced insulation down to 0.88 W/m²K, and FWS 50.SI (Super Insulation) with a Uf value down to 0.70 W/m²K, certified by the Passive House Institute (Darmstadt) for use in passive-standard buildings. The system's installation depth ranges from 6 to 255 mm, the maximum weight of a single infill element is up to 910 kg, and glazing thickness ranges from 4 to 62 mm.

The construction's burglar resistance reaches class RC3, and a special version offers ballistic resistance up to class FB4. Window elements from the Schüco AWS range (including the large-format AWS 114 platform), Schüco ADS door systems, Schüco ASS sliding systems and concealed Schüco TipTronic drives can all be integrated into the facade. The FWS 50.SI version has been awarded Cradle to Cradle Certified status (Silver) by the independent institute C2CPII together with EPEA (Hamburg), for recyclability and minimal content of toxic substances.
