Larsen System


Our Larsen System provides a complete build solution for any client or developer who is seeking to achieve the lowest levels of embodied carbon in their construction.

Complete with all the advantages of factory-produced MMC elements:

  • Cost Certainty
  • Speed of Build
  • Quality Control
  • Improved H&S Benefits
  • Large-Format Production
  • Calculated Psi Values to reduce Cold Bridging

Typically our panels deliver 0.11W/m2K or better, in line with Passiv Haus requirements, and robustly achieve airtightness performance below 1m3/m2/h @ 50 Pa when a complete airtightness strategy is implemented.

Fabric First Approach – In our experience there is always a commercial benefit for adopting a low-energy thermal envelope approach, the slightly increased cost to build is more than offset against cost savings in the lifetime of the completed building.
