    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.
