The wall is the structure, not a thin cladding over a hidden frame, so what you see and sit against is the building itself. We use slow-grown timber on purpose: slow growth in a cold northern climate lays down tight, dense growth rings, which makes the wood stronger, more stable and more naturally resistant than fast-grown softwood, and lets it machine to a precise joint that stays tight. At 44mm this is a thicker solid wall than most barrels on the market, and that timber mass stores heat and gives it back evenly, for a steady, enveloping warmth rather than a heat that drops away the moment the door opens. There is no cavity to trap damp and no hidden insulation to fail, so it is as robust as it is simple. A sauna is roofed and driven hot and dry every session, which keeps rot at bay far better than the weather ever tests it, so this spruce makes a long-lived cabin that takes an oil or a colour beautifully. Prefer a darker, ultra-stable exterior, or the lowest possible winter running cost? We can supply thermowood or a fully insulated cabin too.
