Earth Wool

Description
Knauf Insulation’s EarthWool® Wall and Ceiling Batts are made from highly resilient, inorganic glass fibres bonded by ECOSE® Technology, a revolutionary new binder based on rapidly renewable bio-based materials rather than non-renewable petroleum-based chemicals. ECOSE®Technology reduces Knauf Insulation binder embodied energy and contains no phenol, formaldehyde, acrylics or artificial colours found in traditional glasswool insulation.

Application
EarthWool® Wall and Ceiling Batts provide a cost-effective thermal and acoustical barrier for energy-efficient construction. The batts’ consistent quality, low dust, and clean-cutting resilient wool makes installation fast. EarthWool® Wall and Ceiling Batts can be used in timber and metal frame applications in residential structures. These applications include thermal and acoustical treatments to walls, ceilings and floors. Knauf Insulation offers EarthWool® Wall and Ceiling Batts in a wide range of sizes and R-values.

ECOSE® Technology
Knauf Insulation’s EarthWool® products with ECOSE® Technology benefit from a formaldehyde-free binder made from rapidly renewable bio-based materials instead of petroleum-based chemicals which is up to 70% less energy intensive. The technology has been developed for Knauf Insulation’s glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. EarthWool® products made with ECOSE® Technology contain no dye or artificial colours – the colour is completely natural.
