See the future take shape – Time-lapse from Hällekis

Date Published 2025-10-31

A lot is happening in a short period of time – and now you can see it happen.

Over the summer, our manufacturing facility in Hällekis has undergone major changes as part of our transition project to electric melting technology. Now we invite you to take a look behind the scenes.

In our new time-lapse video, you can see how the building for the electric furnace has grown – from foundation to steel structure – during the months of June to September 2025. It is visual proof of progress, commitment, and faith in the future.

The project includes a 7,500 square meter facility with two new buildings:

🔹 One for the electric furnace

🔹 One for raw material handling and filtration

The electric furnace is scheduled to start operating in early 2027 and will supply stone wool insulation with a low carbon footprint to the entire Scandinavian region.
