Product Features

Spruce Cladding 

Timber selection is crucial to the correct performance of the sauna cabin. Spruce, which has both low heat absorption and low resin content is ideal.  Although it grows in many regions, in the northern areas of Scandinavia the countless generations of experience of nurturing trees, pruning and thinning combine with the cooler weather conditions which slows growth ensuring straight strong timbers.
Specifying top grades means we take only material which is free from dead knots, splits and shakes, the timber is kiln dried in the country of origin, it is then checked again for quality before being assembled into a sauna cabin.
