Debut at ISH 2025: GF Building Flow Solutions, a division of GF, presents leading innovations and proven solutions from the GF and Uponor brands for the building industry.

This episode of Infra Stories highlights the innovative electrical upgrade of Helsinki’s Eastern metro line. Using Uponor’s FastGuard cable protection pipes, the project overcame tight schedules and challenging conditions to enhance safety and efficiency. Listen to the full episode to discover how this smart solution has made Helsinki's metro better equipped to serve its growing transportation needs.

In this episode, we explore the 2024 renovation of the Kirakka water intake plant in Levi, one of Finland’s most popular winter holiday destinations and the annual host of the Alpine Skiing World Cup. Managed by Levi Water Supply and powered by Uponor’s advanced Flowise solutions, this project highlights how tailored infrastructure is addressing the challenges of seasonal water demand in a region that attracts over 600,000 visitors each year. Learn how these upgrades are securing Levi’s water supply and reinforcing its status as a premier winter tourist destination.

In this episode of Infra Stories, we dive into the city of Espoo and its groundbreaking stormwater management project with Ramboll Finland. Espoo was the first city in Finland to install the Uponor Vortex Stormwater Separation Chamber, addressing urban flood risks and maintenance costs caused by rapid development and climate change.

The chamber, installed at a high-flood-risk site in Espoo, uses centrifugal force to keep debris out of water systems, reducing maintenance needs. With increased rainfall intensity, solutions like this position Espoo as a leader in resilient urban planning. Tune in to learn how this innovation is setting a new standard for sustainable stormwater infrastructure.

GF Building Flow Solutions, formerly Uponor, is listed as one of the World’s Most Sustainable Companies for 2024. And Uponor is shortlisted with PEX Pipe Blue for the World Sustainability Awards 2024.

The Uponor Siccus Mini underfloor radiant heating system from GF Building Flow Solutions is dry installation solution, that features a very low construction-height, and a fast installation time.

100 % drinking water quality, 40 % energy savings and 30 % faster installation: Uponor Combi Port and Aqua Port heat interface units for decentralized hot water supply and–depending on the model–for heating and cooling.

• Comparison of decentralized and centralized concepts
• Decentralized systems offer clear advantages for drinking water hygiene and energy consumption
• With decentralized systems, project participants benefit from lower investment costs, planning reliability and shorter installation times
