Flashing behind Hardie board siding, also known as joint flashing, is a weather-resistant material that's installed behind butt joints to prevent water from getting in.
James Hardie recommends using 6-inch wide flashing that overlaps the course below by 1 inch. However, some local building codes may require different sizes.
Sealant is not a recommended replacement for proper flashing.
