Lime Wood (Sauna Interior)

Lime wood is a soft hardwood used in sauna interiors for wall and ceiling cladding, and in some cases for benches. Lime has a light, almost white colour, a fine, even grain with no pronounced knots, and a low resin content. These properties reduce the risk of staining or a sticky surface at high sauna temperatures. The wood has a low density, which contributes to lower thermal conductivity than harder species, although it does not match the values of abachi or aspen. Lime is easy to work and planes to a smooth surface, making it a popular choice for interiors focused on a uniform, light appearance.

Advantages of lime wood

• Even, light appearance: A fine grain with no pronounced knots creates a visually clean, uniform interior.
• Low resin content: Reduces the risk of a sticky surface or staining as the wood is repeatedly heated.
• Good workability: The material planes to a smooth surface, improving comfort on contact with skin.
• Lower thermal conductivity than hardwoods: Low wood density limits rapid heat transfer to the surface layer.
