Radiant Barrier 48"x125'
Designed for high-performance building applications, the rFOIL 4800 NT Radiant Barrier is an ideal solution for use inside sauna rooms as a reflective vapor barrier. Installed behind your sauna wall and ceiling finishes, this foil insulation helps create a more efficient, longer-lasting sauna environment.
The reflective surface works to bounce radiant heat back into the sauna, helping the room heat up faster and maintain consistent temperatures during use. At the same time, the material acts as a moisture barrier, preventing steam from penetrating wall cavities and protecting your structure from mold, mildew, and long-term damage.
Key Benefits for Sauna Use
- Reflects radiant heat back into the sauna for improved heat retention
- Acts as a vapor barrier to control moisture and protect insulation and framing
- Helps maintain stable, even sauna temperatures
- Supports energy efficiency by reducing heat loss
- Lightweight, flexible, and easy to install behind sauna paneling
- Durable, non-toxic material suitable for enclosed environments
Ideal Applications
- Traditional indoor sauna walls and ceilings
- Steam and high-humidity environments requiring moisture control
Installation Notes
Install the foil with an air gap between the barrier and interior wood paneling for optimal reflective performance. Seal seams with foil tape to ensure a continuous vapor barrier.
