Aspen Sauna Material Information

Weight per m³

400 > 425kg per m3 which is very light

Certification

The material is FSC Mix Credit (FSC-MC) certified.

Storage Guidance

It is recommended not to store the material outside, especially in direct sunlight. Thermo Aspen can become lighter in tone, while White Aspen may develop a yellow tint when exposed to prolonged sunlight. To maintain the original appearance, storage away from direct sun exposure is advised.

Maintenance Guidance

Aspen is generally considered a low-maintenance timber for sauna applications, which is one of the reasons it is so popular. The main requirement is ensuring the sauna is properly ventilated and allowed to dry thoroughly after use.

Fitting Tips

Our customers are primarily sauna manufacturers, so we do not directly install the products ourselves. Installation methods can vary between manufacturers. Some use hidden panel clips only, while others use a combination of panel clips and adhesive.

Typical Lengths

Standard stock lengths are:

1800mm, 2100mm, 2400mm, 2700mm and 3000mm

Occasionally, depending on profile and size availability, shorter lengths may also be available:

1000mm, 1200mm, and 1500mm

Lifespan

The lifespan will depend greatly on the environment and level of use, for example whether the sauna is for private or commercial use.

Aspen is regarded as a long-lasting sauna material because it performs very well under repeated heat and humidity cycles. In a properly ventilated sauna, it can remain stable and comfortable for many years.

Key factors affecting lifespan include:

1. Good ventilation
2. Proper drying between sessions
3. Correct installation

External Use

Aspen is intended for internal sauna use only and is not recommended for external cladding applications.

The timber is not treated with oils or varnishes to protect it from weather exposure, and prolonged outdoor use would significantly reduce performance. Additionally, external cladding is generally completed using lower-cost softwoods such as pine.

Key Selling Features of Aspen for Saunas

Aspen offers several advantages over hardwoods and other thermally modified species:

1. Low thermal conductivity, meaning surfaces remain comfortable in high temperatures
2. No resin or sticky sap release when heated
3. Smooth surface with low risk of splintering
4. Excellent stability during repeated heat and humidity changes
5. Reduced likelihood of cracking or twisting over time
6. Thermally modified for superior durability and stability

Recommended Fixings

Fixing methods vary between sauna manufacturers. Common approaches include hidden panel clips, or Stainless Steel Pins. These fixings can be aided with an adhesive.

Recommended Treatment

High-quality sauna Aspen is normally left untreated on walls and ceilings to allow the timber to breathe naturally in high-temperature environments.

Unfinished Use

Aspen sauna materials can absolutely be left unfinished if preferred. Oils and varnishes are not required.

Cleaning Guidance

No specialist cleaning treatment is typically required. The most important factor is ensuring the sauna is properly ventilated and allowed to dry thoroughly after use.
