Earthwool Insulation

 

 

Knauf Insulation's EarthWool™ Ceiling rolls and 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™ Ceiling rolls provide a cost-effective thermal and acoustical barrier for energy-efficient construction. The products consistent quality, low dust, and clean-cutting resilient wool makes installation fast. EarthWool™ Ceiling rolls can be used in timber and metal frame applications in residential structures. These applications include thermal and acoustical treatments to ceilings. Knauf Insulation offers EarthWool™ wall and ceiling insulation in a wide range of sizes and R-values.

Performance

Thermal Conductivity

ASTM C 518 and AS/NZS 4859.1: 2002

Thermal Resistance

ASTM C 653 and AS/NZS 4859.1: 2002

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.
