Sustainability
GIB® plasterboard and compounds are manufactured in New Zealand to support local jobs and our environment1..
GIB® plasterboard is a sustainable, non-toxic, compostable product made from natural gypsum and 100% recycled paper.
The full lifecycle of our products are considered and Winstone Wallboards supports waste minimisation and recycling initiatives both from our manufacturing processes and on construction sites.
GIB® plasterboards do not use fly ash, a derivative of coal extraction, as a bulk filler2. in place of naturally occurring gypsum.
