Create an efficient, well-protected sauna with a professional-grade vapor barrier.
Harvia Aluminium Paper is a high-quality reflective insulation barrier designed specifically for sauna construction. Installed behind the interior wall panels, it helps prevent moisture from penetrating the wall structure while reflecting radiant heat back into the sauna, improving both energy efficiency and long-term durability.
By acting as a vapor barrier, the aluminium paper protects wall insulation from moisture while helping the sauna heat more efficiently and maintain stable operating temperatures. When properly installed and sealed with Harvia Aluminium Tape, it creates a continuous protective layer that contributes to faster heat-up times, improved thermal performance, and extended structural longevity.
Its generous 1.25-meter width and approximately 30 m² coverage make it suitable for complete residential sauna projects as well as larger commercial installations.
Whether building a new sauna or renovating an existing one, Harvia Aluminium Paper provides the professional foundation needed for reliable insulation performance and lasting comfort.
