What profile should I specify for larch cladding?

Profile selection depends on architectural intent and performance requirements. For maximum durability, specify open-jointed profiles (shadow gap or board-on-board) that allow rapid drying and air circulation.

Profile selection depends on architectural intent and performance requirements. For maximum durability, specify open-jointed profiles (shadow gap or board-on-board) that allow rapid drying and air circulation. Shiplap and tongue-and-groove profiles trap moisture at joints and have shorter service lives. Recommended profiles: feather-edge (traditional), board-on-board (contemporary), open rainscreen (high-performance), or hit-and-miss (ventilation applications). Board thickness should be minimum 19 mm for stability, with 22–25 mm preferred for premium installations.
