The Sorting and Collection Process

The process of creating Bronsø starts with sorting out all planks and boards that are typically discarded due to aesthetic “defects”. These imperfections are embraced and become a part of Bronsø’s charm.


1. Collection

  • Discarded planks of pine are set aside during regular production based on specific sorting criteria.


2. Mixing

  • To deliver at scale, profiles, widths, and thicknesses are mixed. The boards are end-matched to simplify the installation process.


3. Installation

  • Bronsø is installed like any other standard facade cladding, making it familiar to most carpenters.


Embracing Material Imperfections

Bronsø proudly embraces material imperfections, which contribute to its unique aesthetic. Here are some of the accepted imperfections:


  • Cracked knots: Without structural implication.
  • Knot corner missing: Adds character to the wood.
  • Knot cracks: Up to 3 mm.
  • Checks: Up to 3 mm.

The Finish of Bronsø

The wood used in Bronsø has a deep golden brown finish resulting from the heat treatment process. Over time, with continued exposure to UV, this finish will turn a beautiful silvery grey. The wood requires no further finishing once it has been thermally treated.
