Why Choose Alder For Your Sauna?

Alder is a hard softwood with an excellent reputation
as a sauna timber due to its low density, moisture resistance, and lack of resin secretion. Historically used for jetties due to its rot resistance, alder performs exceptionally well in humid sauna environments.

✔ Moisture & Rot Resistant – Naturally durable in high humidity and heat.

✔ Smooth, Knot-Free Surface – A refined, uniform finish enhances sauna interiors.

✔ Resin-Free & Cool to Touch – Stays comfortable
to touch in high temperatures.

✔ Warm, Light Colour – Ranges from soft pinkish-brown to deep salmon, enhanced with paraffin oil.

✔ Subtle, Pleasant Aroma – A gentle, hay-like scent in warm sauna conditions.

✔ Affordable – A cost-effective sauna wood choice for home saunas.

✔ Sustainably Sourced – Grade A timber from Finland
& the Baltic regions.

Alder’s slightly darker tone compared to aspen means
it is less likely to show dirt marks, making it an excellent choice for family saunas and outdoor installations.
