Our responsibility. For buildings with a future.
As a system provider and technical partner for aluminium, steel and PVC systems, we combine materials expertise with consultancy and engineering. Together with fabricators, architects and planners and building owners, we consider production, use and maintenance, as well as opportunities for subsequent reuse or material recovery.
Simpler construction: yes. Compromising on quality: no. Because lasting performance is essential to both affordability and sustainability.
Sustainability must be economically viable
Practical to plan. Available. Verifiable. Affordable.
Every project decision brings together requirements for design, quality, cost, timing and availability. We consider these alongside environmental impacts over the life cycle. Sustainable solutions must be practical to plan, available, verifiable and affordable. Simplification should make design and construction easier while preserving the building’s long-term performance, safety and usability.
We see ourselves as enablers. Our aim is to find workable solutions together with fabricators, architects and planners, building owners and our system partners. We translate sustainability objectives into specific material and system choices, assess the available options and develop suitable alternatives where requirements cannot be met immediately.
Four areas of responsibility
- 01
Buildings & life cycle
We consider quality, usability and economic performance throughout a building’s life. This includes material production, operation and opportunities for subsequent adaptation or material recovery.
- 02
Materials & circularity
We support informed material choices and consider retention, repair, reuse and high-quality recycling from the design stage onwards.
- 03
People & collaboration
Responsibility for our employees goes hand in hand with sharing knowledge with customers and partners. Expertise and reliable collaboration provide the foundation for effective solutions.
- 04
Governance & transparency
Responsible conduct shapes our business relationships and decisions. We aim to communicate our principles and the development of our sustainability work clearly and transparently.
Considering the building envelope throughout its life
We support solutions that bring these requirements together within each project. This includes considering how existing buildings can remain in use, be adapted or refurbished. The effects over their service life and the economic viability of the measures are central to our assessment.

Choosing materials carefully. Planning for circularity.
Primary aluminium production is energy-intensive. At the same time, aluminium offers properties that are relevant to durable, high-performance building envelopes. Our assessment considers the specific material grade, its production and its intended use. Appropriate collection, sorting and processing provide the basis for high-quality recycling.
Whether window or façade units can be used again depends on their condition and technical suitability, as well as ease of disassembly, documentation, available quantities and the timing of the projects involved. Testing, responsibilities, storage and logistics must also be addressed. These requirements need to be coordinated at an early stage.
We therefore consider several ways of keeping materials and building components in effective use for as long as possible.
Retain and continue using
Assess maintenance, repair and adaptation options for existing units to extend their service life.
Reuse
Assess whether complete units or suitable components can be used again, based on their condition and the requirements of the new application.
Recover materials
Consider connections that allow disassembly and appropriate sorting during deconstruction.
Recycle to a high standard
Identify suitable recycling routes for each material and create the conditions for recovery at the highest practicable quality.
The conditions of each project determine which approach makes sense. We weigh environmental impacts, technical requirements and costs together, taking account of disassembly, processing, transport and remaining service life.
AKS LC 2.7: a material grade with defined environmental indicators
These indicators relate to the specified aluminium grade and the scope of the corresponding Environmental Product Declaration. Assessing a complete window or façade unit also requires consideration of its other components and the applicable assessment requirements.
Understanding requirements. Exploring options. Finding solutions.
An EPD found online is a starting point for assessment. The fact that an EPD is publicly available for a company or product does not mean that every delivery automatically matches the configuration or material grade it describes. We therefore clarify together what the information covers and how it relates to the intended product and the specific supply. Our aim is to find suitable solutions and support statements with a clear, traceable basis.

Which solution and supporting documents fit your project?
Send us the requirements from your tender or sustainability brief. We will explore the options with you and help identify a suitable approach for your project.
Product information for your building certification
Building certification assesses the interaction of numerous building characteristics and performance criteria. The resulting requirements for windows, doors and façades depend on the selected assessment scheme and the individual project. Schemes in use across our markets include LEED, BREEAM and DGNB/ÖGNI.
Based on these requirements, we work with our specialist teams and system partners to assess the available solutions, product information and supporting documentation. The relevant auditors or certification bodies determine how these contribute to the assessment scheme and evaluate the building.
Responsibility for people. Knowledge for practice.
We share this knowledge with our customers and partners. Through seminars and technical workshops, we help fabricators, architects and planners use systems correctly and put new requirements into practice.

Acting responsibly. Sharing our progress transparently.
We support the direction of the European Green Deal and reflect it in our purchasing decisions. In selecting materials, we aim to consider traceable environmental indicators and appropriate recycled content alongside quality, availability and economic viability. Through specifically agreed material grades such as AKS LC 2.7, we translate this approach into tangible options for our customers.
We base our sustainability communications on substantiated information. We identify the product, part of the business and period to which a statement relates. We present targets, ongoing measures and achieved results clearly and transparently.
Voluntary sustainability reporting under VSME
- We are preparing voluntary sustainability reporting based on the VSME standard. We intend to present key environmental, social and governance information in a structured format. This will also cover our approach to greenhouse gas emissions and our contribution to more resource-efficient value creation.
Dialogue and collaboration across the industry
We contribute our practical experience to industry associations and networks, using this exchange to engage with developments in construction together with our partners.





Frequently asked questions about sustainability and evidence
Finding a way forward for your project, together
Are you planning a project with specific sustainability requirements? Whether these concern material grades, carbon values, recycled content or evidence for building certification, talk to us early. We aim to enable solutions that move your project forward, working with our specialist teams and system partners to assess suitable options, available documentation and possible alternatives.
