Built to Last: Alu alprem’s High-Quality Aluminium Solutions

Built to Last: Alu alprem’s High-Quality Aluminium Solutions A Strong Heritage Alu alprem is one of Slovenia’s oldest metal construction companies, with roots dating back to 1947. The company evolved from small craft workshops and became the first business in the former Yugoslavia to manufacture aluminium windows.

With a strong heritage and a commitment to quality, Alu alprem has established itself as a reliable manufacturer of aluminium windows, curtain wall systems, and panoramic glazing, serving both commercial and luxury residential sectors. The names on its client list speak for themselves: Infineon, Ricola, Geberit, Sandoz/Novartis, Cargo Partner, and Bosch have all trusted Alu alprem to deliver the façade and glazing solutions that define the face of their buildings.

Reliability in Complex Projects Key advantages of Alu alprem include strong in-house engineering, consistent, on-time delivery, and financial stability, reflected in its Platinum AAA credit rating. In an industry where project delays and contractor instability can disrupt even the most carefully planned projects, this level of reliability proves more valuable than it may initially seem.

Growing Beyond Borders Today, Alu alprem operates across multiple international markets, demonstrating its flexibility and growing international presence. The company has a well-established presence in the DACH region (Germany, Austria, and Switzerland), where it not only supplies aluminium joinery but also provides full installation services for projects within a 400 kilometre (km) radius of its Slovenian headquarters.

Outside this 400 km radius, Alu alprem adjusts its approach, focusing on supplying high-quality aluminium elements to projects as far afield as the United Arab Emirates (UAE) and Australia.

These projects demonstrate the company’s ability to deliver advanced systems on time while managing the logistical complexity of international construction projects.

A Foundation for the Future From a small craft workshop nearly 70 years ago to a trusted supplier for some of Europe’s most recognised companies, Alu alprem’s story is one of quiet, consistent growth. As it looks ahead, the company carries the same values that have defined it from the start - precision, reliability, and a commitment to getting the job done right.

A business, quite simply, built to last.

PROJECT: ELES Beričevo Technology Center, Slovenia Alu alprem completed the ELES Beričevo Technology Center in collaboration with Kolektor Koling, marking the third joint project between the companies.

Designed by Scapelab, the building unifies diverse business activities under a single, continuous façade.

It is deliberately contrasted with its surroundings – rather than blending into the nearby rural settlement, it stands apart as a composition of large-scale gestures.

Fire Safety, Energy Efficiency, and Architectural Clarity in One Envelope Alu alprem executed the entire building envelope.

This included a mullion-transom façade, fire-resistant façade systems with integrated doors, and skylights, all delivered using high-performance aluminium systems.

The glass façades feature top-hung windows equipped with electric motors, enabling controlled natural ventilation and enhancing occupant comfort within a highly technical facility. The northern façade incorporates a two-storey fire-resistant EI30 system, demonstrating how advanced safety requirements can be seamlessly combined with architectural openness. Throughout the entire building, lowemissivity (low-e) glass was specified to support the project’s ambitious energy efficiency targets.

“WITH DECADES OF EXPERTISE IN HIGHPERFORMANCE FAÇADE SYSTEMS, ALU ALPREM TRANSFORMS THE MOST DEMANDING ARCHITECTURAL AND TECHNICAL REQUIREMENTS INTO REALITY.”

Prestigious Plečnik Award for ELES Beričevo Technology Center The project received the Plečnik Award, Slovenia’s most prestigious prize in architecture. The award was granted in recognition of the facility’s exceptional structural and technical design, which was fully supported through the implementation of advanced façade systems, ensuring that the architectural intent was met with equal technical precision.

PROJECT Sachsendamm 63–64, Berlin: A Complete Façade Solution in the Heart of the Schöneberger Linse The office building at Sachsendamm 63–64 is one of Berlin-Schöneberg’s most striking new commercial addresses, a seven-storey, 5,400 square metre (sqm) building designed by Thoma Architekten and developed by Gewobag.

dependence on artificial lighting. The combination with a low solar factor significantly reduces solar heat gain, helping to limit overheating and thus striking a good balance between comfort and energy control.

Perforated aluminium sheets in front of the openable windows add a distinctive textural detail to the elevation.

Alu alprem delivered a comprehensive solution, covering curtain walls, windows, doors, and façade cladding as one integrated building envelope.

The Façade: Mullion-Transom Façade combined with Concrete Panels Given the building’s proximity to one of Berlin’s busiest rail hubs, acoustic performance was a key challenge. Alu alprem responded with a layered strategy: sound-proof panels and glazing, an acoustic curtain wall, and additional sound-proof cladding, creating a calm interior despite the urban setting.

The façade is complemented by glass fibre reinforced concrete panels, offering a contemporary aesthetic with excellent durability.

Windows: Performance Meets Natural Light Heat control was the second important demand, reflected in the choice of solar control glass. It allows a high transmission of natural daylight into the interior, providing bright spaces while reducing

Doors: Precision at Every Threshold The building’s mixed-use - offices, a kindergarten and a café - required carefully differentiated access solutions. Main entrances feature polycarbonate glazing and RC2-certified hardware for security, while kindergarten entrances were engineered specifically to meet child safety requirements.

Delivering the Complete Envelope Sachsendamm 63–64 demonstrates what careful material selection and technical expertise can achieve across demanding acoustic, solar, and mixeduse requirements - a project that reflects the depth of experience Alu alprem brings to every façade.
