Thermo Aspen STS4 Cladding (Interior) — 15 x 120 x 2700 mm (per board)

Thermally modified aspen in the STS4 profile — a warm golden-brown sauna board with narrow, angular grooves that give walls and ceilings a crisp, modern line. Aspen is a classic Nordic sauna timber: resin-free, splinter-free and comfortable to the touch, so it won't weep sap or get uncomfortably hot when the stove is roaring. Thermal modification deepens the colour right through the board and adds stability in the heat.
