Spruce panelling is slowly grown, healthy and tough Finnish softwood with sound knots that enliven the surface. Spruce secretes very little resin, and the wood retains its light colour for many years.
Pine panelling is made of pure pine board that has a slightly red tinge. Its looks improve with age, and it darkens beautifully as the years pass. Its faint fragrance of pine resin reminds you of fresh pine forests.
Aspen is a traditional sauna material because of its characteristics. Aspen’s light and even colour is long-lasting and creates a fresh atmosphere inside your sauna.
Alder has a refined shade of red which deepens with age. It’s slightly variegated and easy to care.
