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. 

 1.GIB Barrierline® is manufactured to Winstone Wallboards’ specific specification from a reputable overseas manufacturer.
 2.10mm GIB Aqualine® board uses less than 0.7% fly ash as a processing agent, not as a bulk filler.
