Knauf Insulation’s Earthwool® glasswool is a new generation of insulation made using patented ECOSE® Technology, designed to reduce embodied energy and improve environmental performance.

ECOSE® Technology uses a bio based binder with no added formaldehyde, replacing traditional petroleum based chemicals with renewable materials. This gives Earthwool® its natural brown colour and supports a healthier, more environmentally responsible insulation product.

Made with recycled glass bottles and highly compressed for efficient transport and storage, Earthwool® glasswool offers a more sustainable insulation choice without compromising on performance.

Along with its sustainability benefits, Earthwool® glasswool maintains the thermal, acoustic and fire performance expected from high quality insulation, making it a reliable option for homes, renovations and commercial projects across Northland.

Earthwool glasswool insulation represents a new benchmark for sustainability in construction in New Zealand.
