Pieksäwood — Finnish Sauna Wood Expertise

Pieksäwood is a Finnish family-owned wood manufacturer with more than 70 years of experience in wood processing and manufacturing.

Based in Finland, Pieksäwood has extensive experience producing high-quality wood products for saunas and sauna interiors, including wall panels, bench boards and other sauna components.

The company combines traditional Finnish woodworking expertise with modern manufacturing technology. Pieksäwood also carries out its own heat treatment, allowing careful control over the quality and characteristics of its thermo-treated wood products.

For a sauna project, this means choosing wood from a manufacturer with a long history and specialised experience in Finnish sauna materials.

Thermo-Treated Black Alder

During heat treatment, the Black Alder is treated throughout the wood to develop its distinctive dark brown colour and enhance its natural properties.

The treatment improves the wood's resistance to moisture and decay while also improving its thermal insulation characteristics.

The result is a durable and visually striking material that is particularly well suited to sauna interiors.

The knot-free and resin-free surface provides a clean, elegant appearance and a pleasant feel.

Profile and Dimensions

The panel has a 15 × 90 mm Flat TG (STS) profile, providing a clean and contemporary appearance when installed on sauna walls.

The dark tone of thermo-treated Black Alder works especially well with modern sauna designs and can be combined with lighter woods, stone, glass and other natural materials.

Suitable for Sauna and Interior Design

Although primarily designed for sauna wall panelling, thermo-treated Black Alder can also be used as an interior design material elsewhere in the home.

Its dark colour and natural wood grain make it suitable for creating feature walls and other decorative interior surfaces.

Surface Treatment

The wood can be additionally surface treated.

For sauna applications, we recommend using paraffin oil or sauna wax to help protect the wood surface and enhance the rich brown colour of the thermo-treated Black Alder.

Always ensure that the selected treatment product is suitable for sauna interiors and follow the manufacturer's instructions.
