The GIB Ultraline® PLUS Lining System has been specifically designed and tested to enhance New Zealand homes. The system is a complete lining system specification of GIB® ‘s best practice materials, systems and installation practices. In addition to a high quality interior finish, it can also provide extra performance such as noise control, bracing and even fire rated protection for the home. This can be achieved while using only the one plasterboard product, 13mm GIB Ultraline® PLUS, on walls and ceilings. Winstone Wallboards Limited has received Environmental Choice certification for GIB® plasterboards 13mm or greater in thickness.
