Bronsø

Bronsø is a thermally treated wooden facade cladding. It is upcycled discarded material from a regular production of wooden goods and has 70-80% co2 reduction versus similar products. We have a range of different profile combinations to chose from.

Bronsø thermally treated wooden cladding is upcycled from of discarded material from a regular production of wooden goods. Sorting criteria today means substantial amounts of material is discarded, despite its high quality. The wood is discarded due to knots, checks and other natural tree characteristics, which has no impact on the durability of the wood. These 'mistakes' means the wood is normally sent to a waste management facility for incineration, despite the woods' high value.

*Based on verified LCA calculations. Including phases A1-A3

1 Sorting

We sort out all planks and boards, which normally would be discarded due to aesthetic “defects”, which we embrace

2 Collection

Discarded planks of pine are put to side during regular production based on our sorting criteria

3 Reprofiling

We are reprofiling the boards to make them fit into a system

4 Installation

When it comes to installation, Bronsø is like any other standard facade cladding you might encounter, meaning most carpenters will be familiar and can go straight to the procedure

What happens to wood waste in Denmark?

66kg

Of wood waste is produced per person on average each year in Denmark.

395,000 tonnes of wood waste is produced each year in Denmark

50%

Of wood is recycled into new materials

The remaining half is converted into energy through combustion. Even though around 100,000 tonnes of this wood waste are suitable for recycling, underscoring a significant opportunity to increase recycling efforts.

Wood, as a renewable and ecological material, offers unique benefits for carbon reduction and long-term carbon storage. To fully harness the environmental benefits of wood, two essential considerations must be prioritized: sourcing wood from sustainably managed forests and maximizing the utilization of each tree to minimize waste generation. However, to fully capture these environmental and economic advantages, reuse of wood should be prioritized over recycling. Unlike recycling, which can diminish the structural and aesthetic qualities of wood, reuse preserves the material’s intrinsic value and extends its lifecycle. Prioritizing reuse allows for higher-value applications, reducing the demand for freshly sourced wood and minimizing waste.

From 2016 to 2018, Denmark’s domestic wood consumption rose from 13.1 million to 17.5 million cubic meters. This increase in demand is largely driven by the energy sector, which accounts for 76% of the rise in wood consumption during this period.

The wood has a deep golden brown finish from heat treatment. This will turn a silvery grey with continued exposure to UV. The wood needs no further finishing once it has been thermo treated.

Does it effect the durability that the wood is discarded?
No, the wood is thermo treated all the way through, and the wood is therefore protected in cracks and where nots have fallen out. The wood does not absorb moisture to the same degree as untreated wood.

Does Bronsø contain any hazardous substances?

No, the treatment consists exclusively of the use of heat and steam at temperatures between 190 and 212 ° C. The finished product is 100% natural and completely free of chemicals. During the heat treatment, resin, turpentine, and formaldehyde disappear, which makes the wood resistant to fungal and mould attacks and places the wood in durability class 2 without oil treatment.
What fire retardant/impregnation do you use?
The wood can be delivered fire-impregnated from Burnblock and thus achieves a fire class Bs1d0. The product is made of 100% natural ingredients: 100% biodegradable, 0% toxic substances, PH neutral and Cradle to cradle GOLD certified. Impregnation does not wash out and requires no surface treatment.
Do Bronsø need any surface treatment?
No, without treatment thermo wood is classified as durability class 2 (BS EN 350) “durable” and carries a British Research Establishment (BRE) endorsement stating an expected service life of 30 years when used as cladding and decking.
Can I order a customised Bronsø cladding?
Mix our standard profiles as you want to get a unique look for your project. For large orders we can customise the profile to your needs. However, the thickness will always be 18mm, width of the board is defined by the available stock, and we always deliver in falling lengths.
