K Wall-Line Series

Latham Wall-Line Series expansion joint covers create a neat, reliable junction in both walls and ceilings, indoors or outside. Visible surfaces are supplied in a durable 20-micron clear anodised aluminium as standard, with a brass-colour anodised option on request. The K-range profile is 16 mm deep and can accept an optional water or wind barrier. It installs flush with 16 mm wallboard, while 13 mm board sits almost level with the curved profile, and it can also be surface-mounted or recessed into brick, block or concrete. When the structural joint is 50 mm or wider, the cover can integrate with the Latham Fire Barrier System for added protection.

Every aluminium cover in the Wall-Line Series can be powder-coated or anodised in custom colours to blend seamlessly with the surrounding finishes. Speak with a Latham representative to discuss project-specific requirements. The system accommodates movement in six directions, with the exact range determined by the joint’s physical width and the selected cover size, ensuring long-term performance even in demanding conditions.
