Overview

Movement beads accommodate movement tolerances in plaster and render finishes, which minimises cracking in the finished coat. Two plaster beads are joined with PVC, allowing movement between surfaces caused by differential expansion.

They can also act as a stop where the finish changes on either side.

ApplicationMovement joints and changes of finish.

  • Galvanised for internal use, stainless steel for external use.
