Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Thermo-Treated Solid Wood Construction: Crafted from dark thermo-treated Aspen, these boards are engineered to withstand extreme heat and humidity, making them ideal for sauna environments. The thermal treatment enhances durability and resistance to warping, ensuring longevity even under prolonged exposure to high temperatures.
  • Moisture and Decay Resistance: The solid wood material, combined with thermo-processing, prevents moisture absorption and fungal growth, maintaining structural integrity in steam-rich conditions.

Key features

  • 1. Thermo-Treated Aspen Wood for Enhanced Durability

    • With thermo-treated Aspen wood, you can achieve long-lasting durability in humid sauna environments, outlasting untreated wood by up to 50%* [*Disclaimer: Based on internal testing; actual results may vary]. The heat treatment process eliminates moisture absorption risks, ensuring resistance to decay and warping in high-humidity settings.

  • 2. Precision Tongue-and-Groove Design for Seamless Installation

    • With a precision tongue-and-groove design, you can ensure snug, gap-free installation for a seamless sauna floor or wall, simplifying professional installation compared to traditional interlocking systems*. This design enhances structural stability and heat retention in sauna applications.

  • 3. High Heat Resistance for Intense Sauna Sessions

    • With a heat resistance rating of up to 100°C (212°F), you can maintain structural integrity during intense sauna sessions, enduring temperatures 20% higher than standard sauna woods*. This ensures consistent performance even in commercial-grade sauna environments.

  • 4. Commercial-Grade Durability for Hotel Sauna Applications

    • Designed for commercial sauna environments, you can achieve durable, long-lasting performance in high-traffic hotel facilities, offering 30% better wear resistance than residential-grade sauna wood*. The solid wood construction withstands frequent use without compromising aesthetics or safety.

  • 5. Certified Safety and Compliance for Premium Assurance

    • With EN 322 sauna wood certification, you can ensure compliance with European health and safety standards, backed by eco-friendly and safety certifications. This guarantees non-toxic emissions when heated and adherence to rigorous quality benchmarks.
