Key Advantages of Thermally Treated Wood Battens
Wooden beams and timber battens are essential structural and finishing elements used across a wide range of indoor and outdoor projects. Whether you’re constructing support frames, cladding substructures, or decorative wall systems, these natural wood slats offer both functionality and visual appeal.

Thermally modified from spruce or pine, these timber beams are dimensionally stable, moisture-resistant, and free from chemicals, making them an eco-friendly and reliable choice for modern construction or design.

Durable in All Conditions

Thanks to heat treatment, each beam of wood resists moisture, decay, and warping far better than untreated timber. Ideal for use on terraces, façades, saunas, and other exposed outdoor structures.

Wide Application Range

Use wooden slats and timber battens in wall panel framing, under-deck constructions, outdoor furniture bases, or architectural accents. With various sizes and profiles available, these elements easily adapt to both structural and visual needs.

Natural Finish, Modern Look

The darker tone and smooth surface created by thermal treatment give these wood slats a sleek, contemporary aesthetic, suitable for visible applications where appearance matters.

Environmentally Friendly

With no added chemicals, these wood beams are safe for indoor environments and sustainable construction practices.

FAQ About Wooden Beams and Timber Battens

Can timber battens be used outdoors?

Yes. Thermally treated timber beams and battens are ideal for outdoor use – they withstand humidity, temperature changes, and pests without the need for chemical treatment.

What’s the difference between a beam and a batten?

A wood beam typically refers to a larger structural element, while timber battens and wooden slats are thinner and used for substructures or aesthetic framing. Both can be thermally modified for improved performance.

What sizes are available?

Standard options include thicknesses of 42 mm, with widths ranging from 42 mm to 140 mm. Lengths vary between 2.7 and 5.7 meters, offering flexibility for different projects.

Do these wood slats require high maintenance?

Not at all. Thanks to thermal treatment, these wooden slats are stable and low-maintenance. Occasional oiling helps preserve the rich natural tone but is not mandatory.
