The Swedish National archives

New construction of office space – CLT

Illustration: Tengbom 

In 2024-2025, Granab had the honour of supplying subfloor systems to the offices of northern Europe’s largest archive. The National Archives in Härnösand. The building is a total of 34,000m², of which the archive is 22,600m².

In this building with a CLT frame, 25mm Sylodyn was required to meet the sound requirements. We chose to design S-7000N25.

About the project:

  • Developer/Property owner: Specialfastigheter
  • Contractor: Peab
  • Architect: Tengbom
  • System: S-7000N25
