Insulated boards can be applied to internal or external walls to add to the thermal performance of a building. Employed with PVCu beads and an insulating render or plaster, they can dramatically reduce the amount of energy used during the lifespan of a building.

Internal beads are sometimes referred to generally as plaster beads, but they can also include edge beads, clip beads and shadow gap beads.

Ivory beads are made by Renderplas from recycled PVCu and offer an excellent colour match to many natural shades of render and external paint.
