Carbonzero Org

Our business is underpinned by a philosophy of creating better environments which extends to more than just the products we manufacture. It incorporates the way we operate the business, our manufacturing processes and the way we help our customers create warmer, healthier more energy efficient environments - all while protecting the largest environment of all, our planet.

We have proudly been awarded the World’s first insulation manufacturer to be carboNZero certified.

We feel it is important to consider the environment in all facets of our business and so measuring and monitoring our impact is the only way to understand how we can improve. Our measured carbon emissions will be offset, monitored and continually reduced through a variety of smarter business practices. We can also boast that all our Mammoth polyester insulation products are Red List Free.


The Living Building Challenge developed a Red List of prohibited materials under the Declare Programme to provide transparency around the building products. Declare is a ‘nutrition label’ for the international building industry and is a voluntary self-disclosure programme aiming for healthier and more ecological products in construction. Red List Free products are shown to be free from Declare’s red list of ingredients.
