Thermal modification is a completely organic process that uses heat, steam, and pressure to physically enhance the properties of the wood. Sauna wood that is thermally modified is more dimensionally stable, more water-resistant, has an ideal moisture content, and is far superior to untreated wood for resisting decay, pests, and harmful fungi.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003ePROSAUNAS carefully selects only the finest wood from Northern Europe and Canada, assuring that the quality and consistency of our wood selection is the best available. Our team has more than 55 years of experience crafting premium sauna rooms across North America, and we only offer wood that meets our stringent standards.
