How do the interlocking boards meet their support?
Architectural contextFinished images locate a hypothetical condition. Diagrams show relationships, not approved geometry. Keep project dimensions, fastening and water-management details with the current technical submittal.
Read the relationship
The underside of a covered exterior ceiling
Identify actual board coverage rather than assuming nominal width is exposed width. The interlock is not a substitute for a documented overhead fastening schedule or site-specific movement allowance.
Profile and interface
Tongue-and-groove production section required. Tongue, groove and bevel geometry are not inferred from the family name.
