Ultra is a highly insulating lightweight lime render and lime plaster base coat that is five to ten times thermally more efficient than other lime renders by using lightweight glass bubbles instead of sand. Lime Green's Ultra lime plaster base coat is a lightweight insulating lime plaster base coat that is five to ten times thermally more efficient than other lime plasters. This makes it the perfect plastering base coat for building renovations, where it gives an additional insulation layer to internal walls and protects against salt damage. As an insulating lime plaster, Ultra Lime Plaster is such an effective insulator because it contains an aggregate of hollow beads made from recycled glass, which can make up to 55% of its bulk. This replaces the sand conventionally used in standard commercial lime plasters, which means Ultra Lime Natural uses less energy to manufacture and is significantly lighter to transport, so cutting down on distribution costs and energy. Ultra lime plaster base coat is applied to walls in the same way as conventional lime plasters. It has good ‘workability' and there are no complicated fixings or problems achieving the right depth of coat. PLEASE NOTE: Ultra is made to order and therefore only available for delivery.
