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.

*Per m2, based on external LCA calculations for phases A1-A5, C1-C4

Sorting
We sort out all planks and boards, which normally would be discarded due to aesthetic “defects”, which we embrace
Collection
Discarded planks of pine are put to side during regular production based on our sorting criteria

Reprofiling

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

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

Unique wood features 
Cracked knots
Without structural implication
Knot
Corner missing
Knot cracks
Up to 3mm 
Checks
Up to 3mm 
Silvery grey after time 
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.
