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 binder embodied energy and contains no phenol, formaldehyde, acrylics or artificial colours found in traditional glasswool insulation.
Ecomad have chosen Earthwool as their preferred insulation due to eco-friendliness, performance and ease of use. Having looked at all the aspects of Earthwool, the only thing we found that might be a negative, is the carbon miles created due to Earthwool coming in from various destinations overseas. There is rumour a factory might be built in Australia which would greatly reduce carbon miles.
EarthWool™ Wall and Ceiling Batts and Rolls 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 and Rolls in a wide range of sizes and R-values.
Ecomad does not recommend anything less than R3.5 going into your roof cavity unless there is adequate existing insulation already (but under the minimum recommended values for ceilings) which might only require a top-up. insulation with values less than R3.5 determine
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.
