ProSaunas Alder 1x4 T&G STP

Sauna Wood, Tongue & Groove, STP Profile, Medium-Gap, Wall Material

Prosaunas Alder tongue and groove 1x4 STP profile is a silky-smooth timber that feels comfortable against bare skin in a hot sauna, and is recommended for walls and ceilings.

Prosaunas selects the highest quality Alder with an attractive light color and subtle grain pattern. Alder is durable and naturally water-resistant with a uniform pore structure and even color consistency. Because of its low heat conductivity, Alder is a popular choice for sauna surfaces and will remain comfortable to the touch even in the extreme heat of a sauna.

STP is an elegant profile that produces a refined and attractive wall surface for your sauna with its narrow grooves between broad cladding boards with rounded edges. It can be combined with other wood profiles for a contrasting appearance and to create your own unique, personalized look.
