what goes into a sauna?
how do you make a sauna?
Building a sauna is an art that combines craftsmanship with the use of high-quality materials. Each material plays a specific role in creating a functional, durable, and inviting space. Below, we explore the key materials used in constructing a sauna and their significance to the overall design and performance.
Dimensional Lumber for Framing
The backbone of any sauna, dimensional lumber is used for framing the walls, ceiling, and benches. It provides structural integrity and creates a foundation for the sauna's interior finish. Common choices include spruce, pine, or cedar, with a preference for knot-free wood to ensure a smooth, safe surface.
Plywood for Structural Components
Plywood serves as a strong and flexible material for the structural elements of the sauna, including walls and floors. Exterior-grade or moisture-resistant plywood is typically chosen to withstand the high-humidity conditions. Its versatility and affordability make it a practical choice for hidden but vital layers of the sauna's construction.
Mineral Wool for Insulation
Mineral wool is the preferred insulation material for saunas, providing excellent thermal resistance and soundproofing. Unlike foam insulation, it remains stable at high temperatures and is highly resistant to fire. Mineral wool ensures that heat stays within the sauna while keeping external noise out, creating a peaceful and efficient environment.
glass
High-quality glass is essential for sauna windows, as it allows natural light to enter and connects the sauna to its surroundings. Double-glazed and tempered glass is used to minimize heat loss and withstand the high temperatures and humidity of a sauna environment. Glass adds a touch of elegance and openness while preserving functionality.
something for the roof
A sedum green roof not only provides excellent insulation but also adds a sustainable and aesthetically pleasing element to the sauna. This living roof material retains heat in the winter and cools the building in the summer while blending seamlessly into a natural environment. It also reduces rainwater runoff, making it an eco-friendly option.
Tongue-and-Groove Paneling
Tongue-and-groove paneling is a hallmark of sauna design, used to line the interior walls and ceiling. This method of construction ensures a tight fit and prevents warping over time. Woods such as cedar, aspen, or hemlock are popular choices due to their resistance to heat, humidity, and decay, as well as their natural beauty and aroma.
Tile for Floors
Tile is an ideal material for sauna floors and drainage areas due to its durability, water resistance, and ease of cleaning. Non-slip tiles ensure safety in wet conditions, while their thermal properties help maintain a comfortable temperature underfoot. Proper tiling also enhances the sauna's ability to drain excess water efficiently.
Granite for Stove Stones
Granite is the go-to choice for sauna stove stones due to its excellent heat retention and durability. These stones can withstand extreme heat cycles without cracking, ensuring consistent and gentle steam (löyly) when water is poured over them. Properly chosen granite stones are central to the sauna's ability to deliver an authentic experience.
and everything else
Though less glamorous, high-quality screws, sealants, and finishes are critical for a long-lasting sauna. Stainless steel screws resist rust in humid conditions, while heat-resistant sealants ensure airtight joints around windows and doors. Non-toxic wood finishes preserve the natural look and feel of the wood while protecting it from wear.
