As for vapor barriers, here are options:
Polyethylene Plastic Sheeting
Builders widely use polyethylene sheeting as a standard and highly effective vapor barrier in sauna construction. They typically recommend and install a 6-mil thick sheet on the sauna’s interior side of wall and ceiling structures before applying the sauna paneling. This method effectively blocks moisture from penetrating the walls or insulation.
Aluminum Foil Vapor Barrier
Designed for high-temperature environments like saunas, aluminum foil vapor barriers reflect heat back into the sauna while preventing moisture from escaping into the structure. This type of barrier stands out for its durability and effectiveness in handling the intense sauna environment.
Foil-Faced Insulation
Combining the benefits of insulation with a vapor barrier, you can use foil-faced insulation panels or batts for dual purposes. The insulation retains heat within the sauna, and the foil facing acts as a vapor barrier. This approach significantly enhances sauna efficiency and protects the building’s structure.
Vapor Barrier Paints and Primers
In areas where installing traditional barriers poses challenges, you can apply vapor barrier paints or primers to walls and ceilings. Designed to minimize vapor transmission, these products serve as supplementary measures alongside more robust barrier methods.
Reinforced Vapor Barriers
You can also select polyethylene or other plastic sheets reinforced with scrim or fabric for their added strength and durability in sauna applications. Reinforced vapor barriers, resistant to tearing and puncturing, are an excellent choice for protecting against rough framing or hardware contact.
5. Sauna Materials
Cedar
Cedar is the top choice for many sauna builders due to its natural resistance to moisture, decay, and insect damage. Its pleasant aroma contributes to the relaxing atmosphere of the sauna, and it doesn’t overheat, making it comfortable to touch.
Hemlock
Hemlock is another popular choice, known for its beautiful light color and smooth texture. It offers good resistance to heat and is less aromatic than cedar, which might be preferable for those sensitive to strong scents.
Spruce
Spruce is a traditional choice in many Scandinavian saunas. It features a light color and tight grain, providing excellent heat insulation. Spruce has a subtle, natural scent that can enhance the sauna experience without overwhelming it.
Aspen
Ideal for those with allergies, Aspen is hypoallergenic and does not emit resin or strong odors at high temperatures. Its light color and minimal grain pattern make it a visually appealing choice.
The Use of Stainless Steel
Using stainless steel screws, hinges, and other fasteners and Hardware ensures that your sauna’s structural integrity remains intact over time. They resist rust and corrosion, preventing unsightly stains on wood surfaces.
Installation Tips
1. Sauna Kit vs Custom Build Sauna
Sauna Kits
Pre-made sauna kits are a popular choice for DIY enthusiasts and first-time builders. They typically come with all the necessary components, including wood, heaters, and benches, designed to fit together seamlessly.
The main advantage is convenience and speed of installation, making them ideal for those looking for a straightforward project. However, kits may limit customization options and might not perfectly fit the dimensions or aesthetic preferences you have for your space.
