High Fire Performance

The lamellas are made from solid discarded Douglas fir, adding complexity to fire testing but also making this product unique in the market. Numerous tests have achieved a Bs1d0 classification. An official certification is expected in spring 2024.


Functional and Beautiful Product

The standard version of Flarø FR comes with a black glass fiber cloth but allows for customization. Combined with Gabriel textiles, Flarø FR fits all types of environments. The wooden lamellas vary in dimensions and are arranged in a pattern that remains aesthetically pleasing even when covering large areas.


Acoustic Performance

The acoustic performance is categorized in sound absorption classes from A-E, with A having the highest absorption. The following sound absorption results are based on mounting Flarø FR directly on mineral wool with a thickness of 45 mm:

  • Class: A
  • Weighted Absorption Coefficient: 0.90

Materials and Production Process


  1. Collection: Douglas fir wood for Flarø FR is sourced from a Danish wood manufacturer. The wood is discarded due to knots and cracks.
  2. Milling: The wood is processed at Overgaard Wood in Fredericia, where it is rough cut for production.
  3. Profiling: Profiles are minimized to ensure agile manufacturing and optimized material use.
  4. Manufacturing: The Douglas fir is turned into our final products, such as Flarø Douglas panels.

Material Characteristics

  • Knots: All knots are allowed unless they affect functionality.
  • Grain: Unlike veneered wood, the grain may vary between lamellas.
  • Color: The color varies slightly with the wood’s natural hues.
  • Finish: Our waterborne wax comes in three colors, selectable in the left-hand menu. The wax is spray-applied and maintenance-free, though it can be repainted after many years.
