Comparison: White Cedar vs. Red Cedar for Your Sauna

To choose the right wood for your sauna, it is important to understand the distinct characteristics of white cedar and red cedar. Here is a comparative analysis to help you make the best choice.

Thermal Insulation

White Cedar (Thuja occidentalis) :

• Density: Approximately 320 kg/m³.
• Thermal Insulation: Excellent. The less dense structure traps more air, which improves thermal insulation and helps retain heat better in the sauna.

Western Red Cedar (Thuja plicata) :

• Density: Approximately 385 kg/m³.
• Thermal Insulation: Good. Although red cedar is slightly denser, it provides effective thermal insulation, but slightly less than white cedar.

Structural Quality

White Cedar :

• Rigidity: Good, with a certain flexibility. This wood has fewer knots, providing a more uniform and elegant appearance, ideal for a streamlined design.
• Aesthetics: Fewer knots, more uniform appearance.

Red Cedar :

• Rigidity: Very good, suitable for structures requiring increased strength. Larger bows add character and a rustic touch.
• Aesthetic: Larger and more knots, adding rustic charm.

Sustainability

White Cedar :

• Resistance: Exceptional. Naturally resists rot, mold and insects. Requires little maintenance.
• Longevity: Very durable, perfect for outdoor and humid environments.

Red Cedar :

• Resistance: Very good, but slightly inferior to white cedar. Holds up well to the elements, but may require more maintenance.
• Longevity: Durable with regular maintenance.

Stability

White Cedar :

• Deformation: Very stable with a low tendency to deform under the effect of humidity or temperature variations.
• Shrinkage and Swelling: Less pronounced, ideal for environments with humidity fluctuations.

Red Cedar :

• Warping: Relatively stable, but more likely to warp than white cedar.
• Shrinkage and Swelling: More pronounced, requiring careful management of environmental conditions.

Conclusion: Which Wood Should You Choose for Your Sauna?

White Cedar (Thuja occidentalis)

• Thermal Insulation: Ideal for maintaining constant heat.
• Structural Quality: Good rigidity with a uniform and elegant aesthetic.
• Durability: Exceptional resistance to rot and insects.
• Stability: Very stable, low deformation and swelling.

Western Red Cedar (Thuja plicata)

• Thermal Insulation: Good, but slightly inferior to white cedar.
• Structural Quality: Very good rigidity, rustic aesthetic with larger knots.
• Durability: Very good resistance to rot and insects.
• Stability: Relatively stable, but more prone to deformation and swelling.

Recommendation

For optimal thermal insulation, exceptional durability and great stability, white cedar is an excellent choice for your sauna. If you prefer a more rustic aesthetic with added sturdiness, red cedar is also a very good option. Each type of wood offers unique benefits that can adapt to your specific preferences and needs.
