PROSAUNAS ALDER 1X5 T&G STS4

PROSAUNAS Alder Tongue and Groove 1x5 STS4 Nickel-Gap Profile creates a bold, defined look and is perfect for sauna walls and ceilings. Its silky texture and rich warm hue impart a modern, elegant appearance, and it’s one of the most popular sauna woods in Northern Europe.

PROSAUNAS chooses only the highest quality Alder from Northern Europe.  With an attractive light color and a subtle grain pattern, Alder wood is durable and naturally water-resistant and has an even color consistency. Because of its low heat conductivity, Alder is a great choice for sauna surfaces, and it remains comfortable to touch even in extreme heat.

This elegant profile produces a refined and attractive wall surface for your sauna with defined narrow grooves between broad cladding boards. The crisp nickel-gap spacing creates a sophisticated, modern look. It can be combined with other wood profiles for a contrasting appearance and to create your own unique, personalized look.

PROSAUNAS carefully selects only the finest wood from Northern Europe and Canada, assuring that the quality and consistency of our wood selection is the best available. Our team has more than 55 years of experience crafting premium sauna rooms across North America, and we only offer wood that meets our stringent standards. Because of our total commitment to quality, we can ensure your wood order will arrive to your satisfaction.

Wood Sizing - Nominal vs. Actual Lumber Sizes: In North America, wood sizes are given in "nominal" measurements, which is the lumber’s size when it is cut from moist logs. After shrinkage from drying and surfacing, the actual size of lumber will be less than its nominal size. Please see the diagram for actual dimensions.
