Excellent Insulation that’s Sustainable and Effective

When it comes to ensuring ultimate comfort in extreme weather, EarthWool® Insulation is an excellent, high performing option for your home or office building.

Knauf Insulation’s EarthWool® is an advanced generation of glasswool insulation that provides buildings with a number of protective features, all while looking after the environment. Up to 80% of its composition consists of recycled glass bottles. Furthermore, it can be recycled at the end of the building’s life, making it a highly sustainable choice.

Cost-effective Innovation

EarthWool® Insulation is a fantastic cost-effective option, combining innovative energy saving, sound-absorbing and fire resistance features. This makes it perfect for timber and metal frame applications within residential structures.

At the core of its innovation is a sustainable formaldehyde-free binder, made from rapidly renewable bio-based materials. This binder, known as ECOSE® Technology, is up to 70% less energy intensive than petroleum-based chemical binders. ECOSE® was crafted after five years of intensive research, resulting in natural insulation sheets that contain no dye or artificial colours. This gives it its organic brown colour.

EarthWool® Benefits

Although traditional glasswool insulation already boasts incredible environmental credentials, EarthWool® provides installers and homeowners with additional benefits that are not found in basic glasswool. These include:

  • ‘Super-soft’ glasswool that’s virtually itch free for easier installation
  • Low dust
  • No added artificial colour – it’s naturally brown
  • No chemical smell
  • No added phenol or formaldehyde for enhanced indoor air quality.

It’s also compression packed to reduce transport emissions and keep stockist storage costs low, saving you money while helping the environment.


EarthWool® – The Sustainable Option

EarthWool® Insulation also sets a new benchmark in insulation sustainability, boasting these values:

  • Lower embodied energy than traditional glasswool
  • Made using recycled glass bottles (up to 80%)
  • Can be recycled at the end of building life.
  • Vermin proof and fire resistant.


An R-value specifies the thermal resistance the insulation will provide. Insulation is designed to feature air pockets, with higher R-values signifying more air pockets and a higher level of efficiency.
