Everything You Need for Building a Sauna

Thermo Pine Sauna Battens: Ensure proper ventilation and moisture control in your sauna with high-quality thermo-treated sauna battens. Designed to create a crucial air gap between sauna cladding and insulation, these battens improve airflow, prevent moisture buildup, and enhance the longevity of your sauna structure.

Sustainable: FSC®-certified wood is responsibly sourced and meticulously crafted to ensure exceptional quality.

Versatile: We offer multiple sauna wood types and profiles in a range of dimensions to suit your sauna design. Finnmark’s collection of sauna woods is ideal for a DIY-sauna project or a bespoke home sauna installation.

Durable: We have carefully selected wood types that excel in the heat and humidity of a sauna environment. Finnmark’s collection includes naturally thermo- treated timber, where heat and steam are used to enhance the wood’s dimensional stability and resistance to moisture damage.

Choosing Your Sauna Cladding

Your choice of cladding depends on your personal preference, space, and desired visual impact. Whether you're looking to create a traditional or modern aesthetic, our sauna wood cladding is designed to meet all your interior and exterior needs.

Internal sauna cladding has a large impact on how your sauna room will look, smell and feel, while external cladding ensures a pleasant overall appearance along with resistance to outside influences including harsh weather and destructive wildlife. We offer various cladding widths which can be selected to perfectly fit the size and style of your sauna. Your cladding choice will depend on the sauna space, perspective and visual interest.

Choosing The Right Timber Species & Profile For Your Project

Choosing your panels is all about your personal preference. Finnmark provides a range of styles and sauna wood species to fit the atmosphere and interior you wish to create. When it comes to timber cladding thickness it is imperative to only use cladding boards that are at least 14mm thick. It’s the minimum thickness allowed by law in Finland, and for good reason: cladding thinner than this will invariably warp and become damaged within the sauna’s harsh environment.

The sauna bench wood must be resilient and approx. 28mm thick. Our sauna bench timber comes in SHP-profile.

As for the width of your sauna timber, Finnmark primarily supplies four sizes for the cladding: 90mm, 120mm, 140mm, and 160mm. The sauna bench wood is available in widths from 20mm up to 160mm.
