Pressure-treated decking

Build a long-lasting deck with pressure-treated decking from Norra Timber. Manufactured from Northern Swedish spruce and designed for Nordic conditions, offering durability and the quality required for outdoor environments that stand the test of time.

Top environmental assessment rating

The close annual rings in our northern Swedish pine, which contains a high proportion of heartwood, mean that very little preservative solution penetrates our products. Instead, it is primarily the heartwood’s natural resistance to decay that protects Norra Timber products, reducing the amount of preservative required. As a result, we receive the highest ratings in the various environmental assessment systems, and our in-house treatment process has the lowest environmental impact rating according to Byggvarubedömningen.

We can supply green pressure-treated timber in accordance with the Nordic Wood Preservation Council’s requirements in all the most common construction dimensions and product types: decking, exterior cladding, structural timber, posts and handrails.

About wood preservatives

The wood preservatives used in Sweden are carefully controlled and approved by the Swedish Chemicals Agency and regulated under the EU Biocidal Products Regulation to ensure minimal environmental impact.

The solution used for pressure treatment contains copper salts, the same type of substances used in antifouling paints to control algae. Copper is an essential metal for both people and the natural environment, but at excessive concentrations it can be toxic to aquatic organisms. However, the pressure-treatment solution contains less than four grams of copper per linear metre of timber.
