When sourcing wood flooring, especially for the Australian market, you must prioritize Janka Hardness ratings to ensure durability against heavy foot traffic. For solid timber, look for species like Spotted Gum or Blackbutt, which offer high density. For engineered options, ensure a wear layer of at least 3mm to 6mm to allow for future sanding and refinishing. Additionally, verify the moisture content is stabilized between 8% and 12% to prevent warping or cupping after installation in varied climates.
