Ventilation system made from fossil-free steel installed by Lindab for Castellum

Lindab, a leading ventilation company in Europe, is teaming up with Castellum on a renovation project in Stockholm, Sweden, to use duct systems made of fossil-free steel. This collaboration marks Lindab as the first ventilation company worldwide to receive a pilot delivery of fossil-free steel from SSAB. By opting for fossil-free ventilation ducts, Castellum is making significant strides in reducing the project’s climate impact during the refurbishing process.

Castellum, a property owner, recognizes that a significant portion of their climate impact stems from construction projects. To address this, the company is prioritizing the use of climate-efficient methods, products, and materials in both renovations and new construction projects. In renovation projects specifically, technical installations, including the ventilation system, contribute 50-80 percent of the overall climate impact.

The selected property in Stockholm, built in the 1960s, will now feature duct systems made of fossil-free material with comparable technical properties and the highest tightness class. This decision aligns with Castellum’s commitment to reduce its climate impact. The property is expected to be ready for tenant occupancy by June 2024.

Björn Röber, Head of Property Management Projects at Castellum in the Stockholm region, expressed satisfaction with the collaboration with Lindab, highlighting the opportunity to further reduce climate impact in installation projects. Ola Ringdahl, President and CEO of Lindab, emphasized the importance of such partnerships in mitigating climate impact, praising Castellum’s commitment to sustainability.

The fossil-free steel used in the project is sourced from SSAB and produced using the HYBRIT® technology. Lindab, as a selected partner, has privileged access to a pilot delivery, allowing them to supply products made from fossil-free steel ahead of the planned regular production beginning in 2026. Lindab also offers ventilation ducts in recycled steel as part of its standard range.

Lindab’s innovative approach to utilizing fossil-free steel in ventilation systems demonstrates its dedication to sustainability and environmental responsibility. The collaboration with Castellum underscores the potential for reducing climate impact in construction projects while promoting a healthier indoor environment.
