Ownership structures and legal form

From 1964, Schüco International KG was owned by the OTTO FUCHS limited partnership, a leading international company in the non-ferrous metals industry.

In 2020, both companies were transferred to a holding structure. Since then, Schüco and OTTO FUCHS have been operating as independent subsidiaries under the umbrella of OTTO FUCHS Beteiligungen KG.

Activities and supply chain

The Schüco Group develops and sells system solutions for windows, doors, façades, sliding systems, sun shading systems, ventilation systems and fire protection systems, which are available in the form of around 500 series in total. We also work with our partners to create individual special constructions. Added to this are approximately 50 different fabrication machines, as well as planning, drawing, calculation and project management software. A wide range of comprehensive customer training courses rounds off the product portfolio.

Our core competencies lie in development, procurement, distribution and consultation. This includes advice on certifications, design using sustainable systems, and help with environmental product declarations. We offer solutions for all phases of a building project – from the initial idea, design, fabrication and installation all the way through to after-sales service including maintenance and servicing.

With 6867 employees worldwide, we are working on becoming the leading provider of circular solutions and services for sustainable building envelopes. In order to achieve this aim, we consistently focus on the needs of our customers, which include architects, planning offices, investors and specialist metal fabrication and window construction companies all over the world.

Schüco Carbon Control

In response to European climate policies, we introduced a comprehensive product, service and consultancy concept in 2023 under the name “Schüco Carbon Control” for the sustainable design of building envelopes. It aims to support everyone involved in the construction process throughout the entire life cycle of a building, to enable project-specific CO₂e reductions, and to thereby ensure the future viability and value retention of the building. The collection and recycling of old windows, façade units and other building components is also part of the Carbon Control concept. We see this as a great opportunity to utilise our specific expertise in the field of sustainable building envelopes to the benefit of our customers and our company.

Sustainable product innovations

With our products, we want to help reduce the carbon footprint of the building envelope throughout its entire life cycle and increase its recyclability – from planning right through to dismantling.

Profiles with a reduced carbon footprint

In metal fabrication, Schüco uses “Low Carbon (LC)” and “Ultra Low Carbon (ULC)” aluminium in order to produce profiles with a reduced carbon footprint. We are also providing our customers with low-carbon alternatives in the PVC-U division: The material class “RECYCLED PVC” contains a guaranteed proportion of recycled material while, for its “BIO-ATTRIBUTED PVC”, Schüco uses the non-fossil raw material tall oil, which is a by-product of paper production.

Building-integrated photovoltaics (BIPV)

A building with building-integrated photovoltaics can generate its own energy and then use this electricity to reduce CO₂e and lower its operating costs. Schüco offers a wide range of BIPV modules, which can be integrated with our façade systems in a customised

Recyclable products

A total of 75 aluminium systems from Schüco have been awarded the Cradle to Cradle certificate and are ideal for sustainable building due to their recyclability. Schüco has also developed a concept for a fully circular window under the name “AW Circular”. It aims to reduce the resources used, the emissions and the amount of waste produced over the entire life cycle of the product, while also helping to close material cycles. Different design options make it possible to choose whether to focus on material health, a smaller carbon footprint or the closure of resource loops.

Supply chain

Schüco works with national and international suppliers. We place great value on long-term business relationships that are based on collaborative teamwork. In this way, we also ensure that the quality of our products remains at a consistently high level. For the metal and PVC-U business divisions in Germany, the Purchasing department of Schüco International KG and Schüco Polymer Technologies KG has a list of around 360 direct product-related suppliers, including manufacturers of profiles, fittings and safety/security technology.

Information about the value chain

Schüco does not have any direct relationships with the raw material trade for aluminium and, instead, exclusively procures semi-finished and finished parts. For the Polymer business, the company purchases PVC and additives for PVC processing. As a founding member of the joint venture RE:CORE, which we operate together with the disposal company Remondis, in 2022 we also entered into the field of high-quality recycling of old windows made from PVC-U. With the founding of RE:CORE Metals GmbH in December 2024 and some initial pilot projects, we are gradually expanding the business area of collection and recycling to include further construction materials.

We do not have any figures relating to our indirect suppliers. However, our aim is to utilise our direct influence throughout the supply chain to improve transparency, quality and adherence to environmental and social standards. That is why we are involved, for example, with Aluminium Stewardship Initiative and are members of the VinylPlus industry initiative.

Relevant activities in the reporting period

In May 2023, Schüco Coating Solutions GmbH & Co.KG commenced operations in Wertingen, in the south of Germany. This joint venture combines Schüco expertise in the field of aluminium profiles and the many years of experience of Kemper Oberflächentechnik GmbH & Co. KG, a specialist in powder coating. Coatings are used to increase the corrosion resistance of surfaces or to add colour.

As part of a strategic alliance, Schüco acquired shares in AWB Aluminiumwerk Berlin GmbH in July 2023, which is a long-standing main supplier of the company. The focus here is on the production of reduced-carbon aluminium grades.

In January 2025, Schüco announced the separation of its subsidiary Schüco Interior Systems KG with its production site in Borgholzhausen. The company produces and sells products and interior design systems for industrial customers, including those in the furniture and automotive industries. Rheingold Capital, based in Cologne, took over one hundred percent of the former Schüco Interior Systems on February 1, 2025.

With a minority stake, Schüco has been increasing its existing collaboration with the Austrian Stemeseder Group since February 1, 2024. The aim is to consolidate the partnership on the new product system Schüco Perfect, and to further increase collaboration with regard to development, production and sales. With the cross-trade product solution, a Schüco opening unit is connected to the Perfect Module from Stemeseder to form a unit and can thus be fitted with a sun and insect screen, a window sill, a fall protection system or a threshold.

Furthermore, in June 2024, Schüco invested in Skyline Windows, a leading firm in the American window industry. Through this partnership, the company will become an exclusive distributor of Schüco products in North America – a market that has been identified as having significant growth potential for us with our sustainable technologies.

Schüco also sees opportunities to take market share in China. To do this, we have invested in expanding our local production and service network and have concluded partnerships with eight regional window centres. In future, these will manufacture exclusively for Schüco, bringing our high standards in terms of quality and service to the market there.

In April 2025, Schüco intensified its partnership with LIXIL, a global company based in Japan. LIXIL's medium-term goal is to use one hundred percent recycled aluminum by the 2031 financial year. The cooperation offers Schüco the opportunity to offer CO₂e-reduced aluminum products in both Europe and Southeast Asia and thus meet a growing global demand.
