One、Differences betweenWeather-resistant wood andSauna board
Weather-resistant wood is ordinary wood that has been treated with chemical preservatives to provide properties such as corrosion resistance, moisture resistance, mold and insect resistance, and waterproofing. It is commonly used in contact with soil and damp environments, such as outdoor flooring, construction projects, landscaping, and weather-resistant wooden structures for relaxation and enjoying natural scenery. Weather-resistant wood is also highly favored by landscape designers. However, with the development of scientific technology, weather-resistant wood is now very eco-friendly and is also commonly used in indoor decoration, flooring, and furniture. Interior designers also favor weather-resistant wood.Another type of weather-resistant wood is heat-treated wood, also known as charcoal wood. Charcoal wood is produced by charring the wood's essential nutrients, which eliminates the nutrients that fungi need to survive, thereby preventing decay.

Sauna boards are specialized wood panels specifically designed for sauna rooms. Commonly made from imported softwood and hardwood species like Merbau, these panels undergo special treatments for waterproofing and protection against rot and moisture. This ensures they are environmentally friendly, resistant to water damage, and free from mold and decay. During installation, the two boards are connected using an interlocking system. When used in bathroom ceiling applications, two coats of matte varnish should be applied to protect against moisture. After a heat-degrading treatment, sauna boards are highly heat-resistant and resistant to deformation. Common types of sauna boards include: Larch, Cypress, Pine, Red Cedar, Fir, and Cypress.
Second, which is better for balcony decoration: wood treated for corrosion resistance or sauna boards?
Weather-resistant wood is wood that has been treated to resist decay and is used in outdoor environments. It is available in both board and strip form, and should not be used indoors.
The sauna boards are untreated wood, primarily used for sauna room renovations. They can also be used for creating decorative features in the room.
If the balcony is open, it is recommended to use anti-corrosion wood, which can extend the lifespan of the wood; if the balcony is enclosed, it is recommended to use sauna boards.
