Choosing Sauna Wood: An Overview of Strength and Beauty

The term “sauna wood” describes the particular kinds of wood that are used to build saunas; these woods are selected for their strength, endurance to heat, and visual appeal. Enjoying the ultimate pleasure of sauna therapy is sweating out your everyday worries and tensions. A sauna built into a house is a dream come true for many homeowners.

There are a few things to think about while adding this, but the most important one is the kind of wood. Every kind of wood has distinct qualities that affect the environment and overall experience of the sauna. This post will go over all the elements to take into account throughout the decision process, the best wood choices for sauna construction, and the significance of picking the perfect sauna wood.

Hardwoods vs. Softwoods

It’s important to know the distinctions between hardwoods and softwoods when choosing sauna wood. Each kind has unique benefits and factors to take into account that affect the functionality and comfort of the sauna.

Hardwoods

Hardwoods are derived from trees that stop growing, including poplar, eucalyptus, and basswood. The wood from these trees is tougher and more solid because they grow more slowly than conifers. It’s crucial to remember that hardwood in a sauna absorbs heat, which can make the space unpleasant to touch.

Softwoods

Softwood is a softer and weaker wood that comes from firs that develop quickly. Still, a lot of saunas are built from strong, resilient softwoods like eucalyptus, thermo-spruce, basswood, and cedar. Softwoods are softer and simpler to light, which makes them a popular choice for burning.

Factors for choosing a Sauna Wood

The following factors should be considered while choosing a sauna wood:

Heat-Resistant

It is important to select heat-resistant wood while building your sauna. A wood type that doesn’t absorb heat is important for the best sauna experience because traditional wood-burning saunas can reach levels of up to 200 degrees Fahrenheit. Improper wood selection might compromise comfort and safety by making the sauna uncomfortable to touch. Because they emit less heat than hardwoods, softwoods like white fir or cedar are frequently used in sauna buildings.

Heat Conductivity

How energy moves from a warm to a cold area of wood is measured by its thermal conductivity. To properly retain the heat within the sauna, wood with a reduced thermal conductivity is preferred.

Water-Resistant

Water-resistant wood is essential for maintaining the cleanliness of your sauna, particularly if you use it to create steam by flowing water over hot sauna stones. Perfect wood keeps moisture out of the panels, which might eventually cause discoloration and mold due to moisture or sweat.

Cost

When choosing sauna wood, budget is a key factor to take into account. The least expensive alternative, meanwhile, might suggest a lesser grade. Achieving a cost-quality balance can be achieved by using premium wood in areas that come into direct contact with your skin, such as walls and benches, and using less expensive wood in other areas.

Hardness

Select strong sauna wood that can survive the weather without breaking down to extend the life of your sauna.

Scent

Some sauna fans enjoy the scents of aromatic woods, such as cedar, while others may be allergic or sensitive to the wood phenols that give them off. Select a wood that has a more neutral scent if that’s your preference. Before choosing sauna wood, it’s critical to ascertain your smell preferences.

Densities

Wood typically has a moisture content of 15%, however, this can vary based on the climate and age of the tree.

Opposition to Compression

This number represents the wood’s resistance to splitting, sometimes referred to as drying out. A lower number denotes superior wood suitable for use in saunas.

Antibacterial and anti-fungal

Microbes and molds may grow in a sauna’s warm, humid environment. Choosing a wood type naturally immune to these is a good idea.

Strong Insulator

To maintain the effectiveness and economy of your sauna, your wood should help retain heat.

Which woods are good for saunas?

The best wood can withstand mold, offer thermal comfort, and highlight the material’s inherent beauty now that you are aware of the variables to take into account when choosing sauna wood. The following premium woods offer these desirable qualities for your sauna:

Western red cedar

The most common wood used for outdoor saunas is cedar because it’s the best option overall for building a sauna. For indoor sauna construction, both the clear (knot-free) and rough (visible knots) versions are perfect. Western red cedar is the most widely used type of cedar and is frequently used for:

Roofing Materials.
Outdoor Deck Furniture.
Exterior structure.

Compared to other softwoods, cedar is more resilient and suitable for damp conditions, making it the perfect choice. It is reddish, with a variety of tones that shift with the light and smell characteristics that are appealing. Due to its low density, cedar is a great heat conductor and insulator. It is also strong to warping in the presence of humidity and temperature changes.

Heat-Modified Wood

An even better wood option for saunas is thermally treated wood. Any kind of wood gets harder and is made more durable by this technique. Wood such as spruce, aspen, or pine can be thermally modified to make it more durable and durable than natural wood.

Thermally treated wood has perfect performance and visual qualities, making it appropriate for outdoor construction as well as high-humidity indoor spaces like saunas. The process of treating wood in an air-less environment at high temperatures (185-205 degrees) results in thermowood, which is resistant to moisture absorption, rot, and cracking.

Thermowood offers a distinct feel, antibacterial qualities, and geometric stability. It doesn’t emit any toxic materials, doesn’t decay or mold, and keeps its shape despite variations in temperature and humidity. Companies such as Forever Saunas and Thermory Saunas promote these benefits:

High strength and resistance to wear.
Safe and doesn’t release any dangerous substances.
Increased durability and reduced heat conductivity
Different tones and colors.
Superior qualities for thermal insulation.

White Fir

Another common softwood used in sauna construction is Ross or white pine. It is employed for the following purposes as well:

General building.
Painting projects with hardwood.

More resilient and long-lasting than other softwoods, white fir is the chosen choice. Its light brown color and straight grains, with touches of red or yellow, give it a lovely, similar appearance. A White Fir sauna provides:

Very little to no smell.
Dark brown color with an appearance of either red or yellow.
Resistance to decay and loss of resins.
Unbroken, straight grains.

Best Sauna Woods: Important Mentions

Spruce

Compared to other softwoods, spruce is harder and more sturdy. Many sauna bathers find its unique, calming aroma to be pleasing, and its creamy-white color with hints of yellow. Spruce makes the perfect inside walls, sauna benches, and indoor saunas. Moreover, it’s employed for:

Fences.
Instruments of music such as violin and guitar.
Boards Made of Paper.

Redwood

Redwood’s resistance to warping and early decomposing makes it a great material for sauna building. It works well for garden borders and can withstand wetness.

Exteriors of homes.
Outdoor furniture.
Superior projects, such as artwork or church organs.

Maple

When stained, maple takes on a creamy, yellowish tone, as well as an amber-yellow hue. Maple is a timber that’s frequently used for:

Furniture.
Butcher blocks.
Cut Boards.
Light-colored wooden projects.

Pine

Without heat modification, pine is not the best material since it is weaker than other woods and has a tendency to release resin. Since thermally modified pine is so flexible, it may be easily shaped, easily available, and just as durable as cedar.

Importance of Selecting the Correct Sauna Wood

Choosing the appropriate sauna wood is essential for several reasons:

To Attain Partial Visual Appeal

There’s no better material to improve a sauna’s visual appeal than wood. You can create a sauna that precisely matches your preferred style and design and improves your steam bath experience with the proper wood selection.

To Handle Extreme Heat

A typical sauna session lasts 30 minutes or longer, and during that time, the temperature might vary from 150 to 200 degrees Fahrenheit. In such intense heat, many types of wood can expand, split, or change color; they can even get hot enough to burn your skin. Selecting the proper sauna wood will guarantee that it stays cool to the touch and stable, reducing the risk of burns or other pain while in use.

To Handling Wetness

Depending on the temperature they operate at, saunas can be classified as either wet or dry. While wet saunas create a high-humidity atmosphere by pouring hot water on sauna stones, dry saunas use heated lava stones that produce low humidity. The proper wood for a sauna can withstand high temperatures and humidity without losing its quality or durability over time.

To Offer an Organic Aroma

For frequent sauna users, the scent is just as essential as the temperature. Relaxation and mental health can be improved by a pleasing and well-balanced aroma. Certain woods, such as eastern red cedar, have pleasant scents that they naturally release. These scents can gently fill your sauna and provide an all-natural aromatic experience.

Conclusion

Sauna fans have lots of wonderful wood selections to choose from when building a sauna. When selecting the ideal sauna wood, take into account the things that are most important to you, such as your budget, the location of the sauna, and whether or not you want fragrant wood.

Because of their strength and resistance to the weather, thermally treated wood and cedar are excellent materials for outdoor saunas. You may choose the perfect wood that suits your tastes and guarantees an excellent sauna experience by weighing these important considerations.
