Western red Cedar processing

Western Red CedarUnlike other infrared sauna manufacturers, INFRADOC® has one very significant difference. Mostly the cedar that is cut and to be dried it's put to the high-temperature thermal cabins or stoves to accelerate the drying process. The disadvantage of this method of drying is that all natural essential oils kept inside the wood is burning out with water molecules under the high-temperatures.

The cedar that is used for INFRADOC® cabin production is naturally dried for minimum of 6 weeks under the sun to preserve the wood's natural state. This method also guarantees that the wood will keep all essential oils that has the unique ability to kill bacteria and mold, keeping your sauna smelling fresh. The wood will never bend out of form, crack or lose its colour. The rich, inviting aroma of grade-A cedar will smell the same from the time you first brought it into your home; so natural and pleasing to be surrounded by. Cedar has been used over the centuries because of its ability to be anti-bacterial and naturally keep away pests and insects.
