To combat moisture, wood must be dried sufficiently. Wood should be split, stacked and covered in the summer months so that it is ready when needed. A woodpile should be protected from precipitation, but the sides should remain exposed to allow the stack to continue drying. A moisture content of 20 percent or less is ideal. Green birch and aspen can contain up to 80 percent moisture by weight. The inefficiency of burning anything more than 20 percent moisture leads to progressive increases in creosote and particulates.
If you want the full story on wood-burning in the Interior, along with a wealth of information regarding proper burning techniques, the Fairbanks North Star Borough is putting on two open houses on wood burning and PM 2.5 next week.
The open houses take place Tuesday at the Morris Thompson Cultural and Visitor’s Center and Wednesday at the North Pole Middle School cafeteria.
The “Ask a Builder” series is dedicated to answering some of the many questions Fairbanks residents have about building, energy and the many other parts of home life.
