FAQ’s

  • Frequently Asked Questions
  1. What is the required dryness for wood?

    Construction lumber requires less than 15% moisture content.
    Internal projects require less than 8% moisture content.

  2. How long does wood take to kiln dry lumber?

    Kiln-dried refers to dried in an oven (kiln). With a kiln, you can control the environment such as temperature, humidity, and steam levels for a set period of time. Allowing you to dry wood to the desired moisture content faster than air-drying.

    Softwood takes approximately 10 days and hardwood takes 14 days to reach 8% moisture content, depending on thickness and species.

  3. What is the difference between linear foot vs board foot?

    -Linear Foot is 1 foot in length or 12 inches. It is a measurement of a straight line.
    -Board Foot is a measurement of volume. A board foot is one square foot, one inch thick. Board footage is calculated by multiplying the nominal thickness in inches (T) by the nominal width in inches (W) by the actual length in inches (L) and dividing by 144. The formula is: T x W x L  / 144 = Board ft.
    These measurements are often confused. When calculating amount of materials and prices, check the measurement units being used in calculations.

  4. Graded lumber versus non-graded, what is the difference?

    Graded lumber will be available from Malwood Sawmills in the future.

    As per the Ontario Building Code: “Ungraded lumber may be used for wood posts, joists, rafters, lintels, beams and wall studs in a farm building of low human occupancy of not more than one storey in building height.”

    Graded or stamped lumber pertains to the rules for lumber used in the actual structure of the home or occupied dwelling. Lumber for trim, flooring, paneling are not required to be graded.

    The National Lumber Grades Authority (NLGA) is the organization responsible for the establishment, issuance, publication, amendment and interpretation of Canadian lumber grading rules and standards.  NLGA is the only recognized rules writing body for lumber grades and standards in Canada.

    The Canadian Lumber Standards Accreditation Board (CLSAB) is the official body that monitors the quality of Canada’s lumber grading and identification system. For more information, visit: https://www.clsab.ca/

  5. Is a 2×4 a 2×4?

    In the past, when a timber was called a 2×4 [or “two-by-four”], it actually measured 2 inches by 4 inches. Now, most timber is milled to 2’ x 4” and planed for a smoother surface and finished look. Instead, a 2×4 is really only 1 1/2″ by 3 1/2″.
