Winstone Wallboards Ltd is New Zealand’s only manufacturer and largest marketer of gypsum plasterboard, drywall systems, associated products and services. The company has been operating since 1927 and manufactures plasterboard systems under the GIB® brand name. Winstone Wallboards Ltd, has facilities in Auckland, Wellington and Christchurch. The GIB® brand is a New Zealand icon brand and Winstone Wallboards has a proud heritage of being a New Zealand focused and New Zealand based company. Locally made for local conditions, the products meet or exceed the New Zealand building code, are BRANZ appraised and are backed by full technical information and support to give complete confidence in using GIB® Plasterboard Systems.
The Winstone Wallboards warranty covers GIB® products and/or systems for a minimum of 10 years from the date of purchase. Winstone Wallboards warrants that GIB® products will be free from defects caused by factory workmanship or materials and, subject to compliance with the conditions attached, that the product or system will perform to the extent set out in relevant Winstone Wallboards published literature current at the time of installation.
GIB® plasterboard is a sustainable, non-toxic, compostable product made from natural gypsum and 100% recycled paper. GIB® plasterboards do not use fly ash, a derivative of coal extraction, as a bulk filler* in place of naturally occurring gypsum.
Our GIB® products have an EPD developed in accordance with ISO 14025 and EN 15804 and have achieved Environmental Choice New Zealand accreditation which may help your project achieve points under ISv1.2 Mat-2 and ISv2.0 Rso-7. In addition, our EPD data has been included in the ISv2.0 Materials Calculator meaning when you use our product on your project/asset, you can select the appropriate GIB® product within the calculator.
Winstone Wallboards works closely with local waste companies on initiatives to recycle plasterboard waste. Plasterboard is collected separately from general building and construction waste and the waste volumes and tonnages are recorded and reported per project for contractors and their customers. This allows plasterboard recovery statistics to be provided as part of total site landfill diversion and environmental reporting for ISCA (ISv1.2 Was-2, ISv2.0 Rso-4), Greenstar and Homestar accreditation.
In Christchurch, plasterboard manufacturing waste from Winstone Wallboards in Christchurch is processed by Canterbury Landscape Supplies with off-cuts shredded and screened to return it to gypsum form. The recycled gypsum is supplied as a soil conditioner to farmers, freight companies, orchards and vineyards.
GIB® plasterboard and compounds are manufactured in New Zealand**. We have complete oversight of our factory conditions and the teams who work in our manufacturing plants. Our decision to manufacture locally supports local jobs and directly supports the country’s economy and may support your sustainable procurement strategy (ISv2.0 Spr-1).
* 10mm GIB Aqualine® board uses less than 0.7% fly ash as a processing agent, not as a bulk filler.
**Note: GIB Barrierline® plasterboard is manufactured to Winstone Wallboards’ specific specification from a reputable overseas manufacturer.
