Common Types of Wood Used in Saunas

When selecting wood for saunas, it is essential to consider factors such as heat resistance, durability, and minimal resin content. Here are the most common types of wood used:

  • Cedar: Known for its natural resistance to moisture and decay, cedar is a popular choice. Its pleasant aroma and beautiful appearance enhance the sauna experience.
  • Hemlock: This wood is less aromatic than cedar but is often favored for its strength and stability. Hemlock is also less expensive and provides a clean, modern look.
  • Spruce: A cost-effective option, spruce is lightweight and has good insulation properties. It is less durable than cedar and hemlock but can be treated for improved longevity.
  • Pine: Although it can release resin at higher temperatures, pine is still used in some sauna constructions. It is essential to choose kiln-dried pine to minimize resin issues.

Characteristics of Ideal Sauna Wood

The ideal wood for sauna construction should exhibit specific characteristics to ensure a comfortable and safe environment:

  • Low Thermal Conductivity: This property allows the wood to remain cool to the touch, preventing burns.
  • Minimal Shrinkage: Wood that shrinks less when heated maintains structural integrity and appearance.
  • Natural Resistance to Decay: Resistance to moisture and insects is crucial for the longevity of the sauna.
  • Aromatic Qualities: Many users appreciate the pleasant scent that certain woods emit when heated.
Wood Type Moisture Resistance Aroma Cost
Cedar High Strong High
Hemlock Moderate Minimal Medium
Spruce Moderate Minimal Low
Pine Variable Strong (when heated) Low

Wood Treatment and Maintenance

Proper treatment and maintenance of sauna wood are crucial for longevity and performance. Here are some guidelines:

  • Kiln Drying: Ensures that the wood is moisture-free, reducing the risk of warping and cracking.
  • Regular Cleaning: Use a mild soap solution to clean the surfaces without damaging the wood.
  • Avoid Chemicals: Refrain from using harsh chemicals or cleaners that can harm the wood’s finish.
  • Inspection: Periodically inspect for signs of wear, such as splintering or discoloration, and address issues promptly.

By selecting the right wood and adhering to maintenance practices, sauna owners can enjoy a beautiful and functional sauna for many years.
