Safety is a Huge Concern When Using a Sauna.
Many users look to QCA Saunas for health and detoxification purposes, so we want to make sure our saunas are made of the safest components to enhance the benefits of infrared, rather than hinder it. This is why our saunas are hand-crafted in the USA; we have an attention to detail that we feel is important when making saunas and it cannot be achieved by cookie-cutter production.
Far-infrared energy heats objects directly and penetrates up to 2 inches below the surface. This means the infrared heat also penetrates the sauna wood in addition to your skin, so the wood that a sauna is made of is very important. Cedar and redwood contain a natural insecticide within these wood called terpenes. When a sauna made of cedar or redwood is turned on, these naturally occurring oils within the wood become heated and gas off a substance called Cedrine. It attacks the central nervous system of insects and kills them. In some cases, it can also cause vomiting and convulsions in humans.
Aspen is a light wood that is a member of the poplar genus of trees in the willow family. It is native to the Rocky Mountain Region and Colorado, and is closely related to cottonwood. Aspen wood is known for its rustic look and is often used for furniture, paneling, veneer products, and more.
QCA Saunas are made of 99% non-toxic aspen hardwood, which is a clear wood grown at elevations where the trees do not produce an insecticide. Our aspen wood is carefully chosen, and we make sure that all of our aspen wood is furniture grade. Other saunas have thinner wood and are much less durable, where we use only the thickest and most durable wood, 2-3 times thicker than our competitors!
