At the Step Change 2025 event series, innovative start-ups and scale-up companies that participated in the event held in June 2025 were introduced at the Nokia Arena in Tampere, Finland.
UBLO Inc. is a Korean startup founded in 2018 by Korean architect Naree Kim and Dutch architect Robert-Jan van Santen. It creates minimalist windows with the planet and people in mind, aiming to reduce both embodied and operational carbon emissions by simplifying components to minimise frame usage and creating energy-efficient windows.
No frames, just a smart, minimalist aperture and lid system. From prototype to product, UBLO’s journey shows how innovation meets real-world needs, especially in cold climates like Finland.
The Step Change 2025 event, which brought together startups, scale-ups, and glass experts from around the world, was organised by Glaston in collaboration with glasstec – International Trade Fair, in conjunction with the Glass Performance Days (GPD) conference.
