Alder has long been known as nature’s perfect sauna companion, with natural water-repellent properties and optimal thermal conductivity to prevent overheating while creating a comfortable, balanced sauna environment. The distinctive reddish tones, understated honey-like smell, and pleasant texture make alder a safe choice with mass appeal.

    1X5 Brushed Black Alder STS4 Wall Cladding – Sauna Wood by Thermory

    Thermory
    Price range: $4.56 through $268.00

    Looking for a smooth, black sauna wood with a professional finish?  The wire-brushed black wax alder by Thermory is a perfect choice for a durable finish.  Whether contrasting with woods like thermo-aspen or going all dark for the ancient ‘smoke sauna’ look this STS4 1×5 is an ideal choice for a wide plank wall and ceiling cladding.  Actual wall coverage is 4.4″.

    Note: Brushed black alder does NOT have the burnt Shou Sugi Ban (yakisugi) look as other websites incorrectly show.  Please ask us about ‘Thermory Ignite’ for that.
