Movement Beads are only available in one length of 3000mm. They are used to compensate for movement in plaster or in situations that must allow for thermal movement and prevent cracking. They can also be used as a stop barrier for a change in finish. They are made using a PVC extrusion covered with vinyl tape (removed after plastering) in the middle of two plaster stop lengths to allow up to 4mm of movement.
