    Spruce Sauna Cladding T&G V-Joint (Extra) 19×146mm is a clean, stable and cost-effective solution for lining sauna walls and ceilings. Machined from high-quality Nordic spruce, this profile is designed specifically for internal heat environments where consistency, low resin content and a smooth tactile finish matter.

    The tongue and groove (T&G) system allows for tight, precise installation, while the V-joint detail creates a subtle shadow line between boards — delivering a crisp, uniform finish. The 19mm thickness provides structural stability for internal use, while the 146mm face width ensures efficient coverage and balanced proportions.

    Supplied planed all round (PAR) with a smooth finish, this cladding is suitable for direct use in sauna environments without additional machining. Spruce is widely used in sauna construction due to its light tone, consistent appearance, and comfortable surface temperature under heat.

    Why Spruce for Sauna Cladding

    Spruce is a proven choice for sauna interiors due to its reliable performance in high-temperature environments. It offers a balanced combination of stability, appearance, and cost efficiency.

    • Low thermal conductivity – comfortable to touch
    • Stable in controlled indoor conditions
    • Clean, uniform appearance
    • Cost-effective alternative to premium species

    Installation Overview

    Boards can be installed horizontally or vertically using the tongue and groove connection, fixed onto a timber batten substructure. A ventilated cavity behind the cladding is recommended to allow airflow and prevent moisture build-up.

    • Recommended batten centres: 400–600mm
    • Allow for expansion where required
    • Use stainless steel fixings
    • Ensure airflow behind boards

    Where to Use

    • Sauna wall cladding
    • Sauna ceiling lining
    • Internal spa and wellness rooms
    • Dry heat environments

    Important Considerations

    • For internal use only (not suitable for external applications)
    • Natural variation in colour and grain should be expected
    • For seating, use dedicated sauna bench boards
