What material are sauna boards made of?

2025-10-18

Sauna boards are made of solid wood and are specialized for bathrooms. They are typically made from imported pine and South Sea hardwood, and are treated with waterproofing and anti-corrosion treatments. They are environmentally friendly and water-resistant, eliminating the risk of mold or rot.

Sauna boards are the most mature technology, with two panels connected by a plug-in system. If used in bathroom ceilings, they require two coats of matte varnish for moisture resistance. Sauna boards are a type of wood specifically designed for sauna rooms, featuring plug-in connections for easy installation. They undergo a high-temperature degreasing process, making them heat-resistant and non-deformable. Sauna boards are primarily made from fir, camphor pine, white pine, red spruce, hemlock, and cedar.

Sauna panels have a wide range of uses, the most common being sauna rooms, where white pine and red cedar are generally chosen. Pinus sylvestris is best avoided due to its oiliness. Wall panels are used for large interior and exterior wall panels. Outdoor thickness is generally 15-16mm and width is 120-150mm, with smaller dimensions indoors. Bathroom and balcony ceilings can be used for partial applications, as can bay windows and partial walls. In short, the design and application should be tailored to the specific application.

Sauna panels are made from oven-dried Scots pine and red cedar lumber for sauna room siding. While sauna panels are typically oven-dried, some manufacturers, to save costs, skip the cost of degreasing, instead grading and removing any grease. Imported Canadian red cedar is currently popular, while Russian Scots pine is sometimes used in less demanding sauna rooms. However, oven-dried Scots pine and red cedar are more suitable materials due to their superior texture and attractive knotty texture. Other materials tend to release pine oil when heated. Three key considerations for selecting sauna panels are: aesthetically pleasing material, size, and finish.

Common sizes of red cedar: 10*100*2750 and 10x100x2750mm, divided into paint-free and non-paint-free, can be customized according to customer requirements.

1. Material: Sauna boards are primarily made from materials such as Finnish spruce, Scots pine, Korean cedar, as well as hemlock and Douglas fir. Red cedar sauna boards are knot-free, feature clear grain, a bright color, a superior texture, and fine workmanship. They are available in either paint-free or non-paint-free varieties. Scots pine sauna boards are the most popular, offering a low price and excellent quality. Red cedar sauna boards are dimensionally stable, resist deformation, and have a natural fragrance, making them ideal for sauna rooms. Red cedar is a naturally rot-resistant wood. Untreated, red cedar resists rot, mildew, and decay. Hemlock and Douglas fir also have their own unique characteristics, and customers often choose based on their preferences. Sauna boards are also available in either knotty or knotless varieties, with knotless materials being significantly more expensive.

Sauna board materials are mainly Finnish spruce and Scotch pine

2. Size of Pinus sylvestris: 10x100 is more commonly usedx4000mm and 12X100x4000mm, width 85-100mm are also more common.

3. Processing and production level: The first is processing accuracy, including dimensional error and surface finish; the second is sorting level, whether the grading is strict and defective plates are removed.

4. The sauna board is made of drying materials, so the product is not easy to deform or mold.
