The packages must not lie directly on the ground; place them on joists and cover them.

Disposal
The treatment consists exclusively of the use of heat and steam, so the finished product is 100% natural and completely free of chemicals.

At disposal, the wood is handed in at a recycling station or recycling centre.

Basic treatment
The cladding boards are heat-treated at temperatures between 190 and 212 ° C. 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.

The treatment consists exclusively of the use of heat and steam, so the finished product is 100% natural and completely free of chemicals.

It is a consistent treatment, and the wood is therefore protected at the ends as well as cracks.

The wood achieves good dimensional stability, does not absorb moisture to the same degree as untreated wood. The product is particularly suitable for outdoor clothing. The product does not withstand direct ground contact.

The wood has a density between 390 and 430 kg / m3 at 5% wood moisture.

Maintenance
Thermal wood as a rule does not need to be maintained and has an expected shelf life of 20 years or more when the wood is used and maintained in accordance with the Tree Information guidelines.

If the profiles are used untreated, they will patina in a grey to silver-grey shade. However, there will be a risk of attack by surface mould if boards are mounted in exposed places. This will discolour the clothing. If the cladding is infested with mould, the cladding can be washed down with wood cleaner, after which the cladding will again appear nice and silver grey.

There will be a difference in how often it must be maintained depending on location, but typically after 1-5 years. South facing requires most maintenance. The wood is inspected once a year and cleaned of dirt, insects etc., which can form a breeding ground for algae and mould growth.

Surface expression
The thermal treatment gives the wood a warm brownish glow, which can vary from board to board. Bronsø has a variegated look with many knots. The amount of knots will vary, but the pictures the the right illustrates what should be expected.

The thermal treatment is a consistent treatment, and the wood is therefore protected at the ends as well as cracks. If the wood is used untreated, it will patina to a greyish colour when exposed to UV light. This will take place over approx. 3-6 months after installation depending on light intensity and location and will continue until the wood reaches saturation.

If the heat treatment is combined with a linseed oil treatment, the warm brown colour can be preserved.

On the right are a few examples of knots and checks in the wood, that are acceptable for the Bronsø product.
