isophon glas wins the SANCO Reference Award

The SANCO Reference Award 2025 has been presented to the family-owned company isophon glas of Hannoversch Münden. The long-standing SANCO partner is being honoured for its outstanding glass solution used in the Hamburg residential development Eleven Decks. The jury praised the project for its technical excellence, architectural quality, and exemplary combination of sustainability and innovation.

Award-winning architecture with character

With 306 apartments, Eleven Decks is one of the largest privately financed residential developments in Hamburg’s HafenCity. Rising above the ground-floor retail area, the building steps up to eleven storeys and offers a wide range of apartment types – from one-room units to a penthouse with landscaped roof terraces. The concept is complemented by a variety of shared spaces, including co-working areas, fitness and yoga rooms, a club-style social area with open kitchen, and a communal barbecue area. Designed by CARSTEN ROTH ARCHITEKT, the building has already received several awards, including the German Design Award 2024 and Residential Buildings of the Year 2025. Eleven Decks has also achieved international BREEAM ‘Excellent’ certification for ecological and socio-cultural sustainability.

Glass as a defining façade element

For the project, isophon glas supplied a state-of-the-art triple-glazed insulating glass unit, which was complemented on the street-facing loggias by a suspended impact pane featuring an anti-condensation coating. The combination meets the highest requirements in terms of sound and thermal insulation, while also ensuring clear views and a pleasant indoor climate – a key contribution to the high level of living comfort in the dense urban environment of HafenCity. ‘The glass façade of Eleven Decks impressively demonstrates how technical innovation and architectural design can go hand in hand,’ the jury stated in its citation.

Tradition meets innovation

Based in Hannoversch Münden, the family-owned company isophon glas has specialised in the manufacture and installation of high-quality glass products since 1979. With around 200 employees, the company produces insulating glass, laminated safety glass and toughened safety glass for demanding construction projects across Europe. ‘We are delighted to receive this award, which highlights our commitment to quality and sustainability through contemporary glass solutions,’ says Carolin Biletic, Authorised Signatory at isophon glas. Antonio Gioello, Head of SANCO Consulting, adds: ‘isophon glas perfectly exemplifies what defines SANCO partners – professional excellence, a passion for glass, and a shared commitment to sustainable construction.’
