Wall, Wall-to-Ceiling and Ceiling Expansion Joint Covers in Aluminium 

The Latham Wall-Line Series of expansion joint covers are specifically designed for wall and ceiling applications. There are a variety of systems which range from spring fixings details to mechanical fixed details in full aluminium or aluminium and Santoprene inserts. Some systems in the range allow 6 way movement, whilst the surface fixed products generally cover 2 directional movement. The systems offer thermal and structural movement and shrinkage and will accommodate limited seismic movement.

The Latham Wall-Line Series Standard wall and ceiling expansion joint covers are for internal and external applications. As standard all visual surfaces come with a 20 micron clear anodised finish (standard) or brass colour anodised finish (specify brass colour finish). The standard K range is 16mm deep and can carry a water/wind barrier if required. The range can be installed flush internally with 16mm wall board or the curvature of the profile 13mm board will appear almost flush, surface mounted or recessed brick, block work or concrete. When the expansion joint width is 50mm or wider, the range can accommodate the Latham Fire Barrier system.

All Wall-Line Series aluminium expansion joint covers can be successfully powder coated or anodised to harmonize with the wall and ceiling finish. If this is required please contact a Latham representative to discuss the application. The systems offer various movements in 6 directions. The actual movement available will depend on the physical structural joint width and the installation width for the expansion joint cover.
