ECOSE® Technology
A revolutionary, bio-based binder with no added formaldehyde or harsh chemicals. This breakthrough technology ensures safer installation and a healthier living environment.
Cleanest Air Quality
Industry-leading low-dust technology means the healthiest insulation for your home. Precision fibre technology virtually eliminates airborne particles, keeping your family breathing cleaner air.
Sustainability
Manufactured from up to 80% recycled glass, Earthwool represents our commitment to environmental responsibility without compromising on performance.
VOC Mastery
Awarded the 'Red List Free' label, it creates a healthier indoor air environment with ultra-low emissions. Breathe easier knowing your insulation is certified safe.
Thermal Inertia
Higher R-values create a 'Thermal Shield' that prevents your HVAC system from constant cycling, prolonging equipment life and reducing energy bills significantly.
The Comfort Estimator
See how upgrading your insulation transforms your home's thermal protection.
Base efficiency: 20%
Understanding Thermal Bridging
Standard insulation leaves the ceiling joists exposed, allowing up to 30% of heat to bypass the barrier through thermal bridging. Only R7.0 and R8.0 provide "Complete Coverage" that eliminates these gaps.
