Havelock Wool Insulation


Homes are increasingly sick. Sheep wool provides an unparalleled solution to an increasing challenge in the built environment.  “All other forms of insulation are unhealthy at best, toxic at worst and ineffective by comparison.”

Consider what happens to your indoor air quality when you insulate with subpar materials and your house doesn’t breathe properly. Per the EPA, indoor pollutants increase when there is not enough fresh air in a home.

Don’t let your builder, architect or insulation installer be in charge of your health.  Their interests are not always aligned with yours so make sure you inquire on all materials in your home.

Optimally, you should have a chemical-free passive filtration insulating material that insulates well, manages moisture and reduces sound. It’s good for your home, your family and the environment.

Why more people are using wool in their walls

  • Conventional insulation underperforms: subpar materials = subpar performance.
  • Indoor air quality matters: most conventional materials emit particulate or harmful chemicals.
  • Insulation needs to manage moisture:  with more and more air tight structures, condensation inside your walls is inevitable.
  • Sustainable building is the right thing to do for your family and for the planet

For those who want to know their home is built of high integrity materials that not only perform well but create a healthy environment, you are in luck as these materials are on the rise. Wool insulation is one of them.


Havelock Wool Insulation Improves Indoor Air Quality:

  • Wool insulation does not off-gas harmful chemicals.
  • Wool fibers serve as an air filter.
  • The amino acids in wool insulation bond with (and lock up) harmful chemicals such as formaldehyde, nitrogen oxide and sulphur dioxide on a molecular level.
  • Wool is hypo-allergenic – making it well-suited for those who are chemically sensitive.
  • The EPA suggests that indoor air quality is 2-5x worse than outdoor.

Havelock Wool Insulation Manages Moisture

  • Wool fibers manage moisture by absorbing and releasing moisture against 65% relative humidity.
  • Wool prevents condensation by generating heat from energy, making it warm when wet.
  • Moisture is inevitable; wool’s inherent management capabilities allow for longer lasting products.
  • Wool is a keratin and will not support the growth of mold.

Havelock Wool Insulation Absorbs Sound

  • Wool exceeds other forms of insulation as an acoustic buffer.
  • Sheep’s wool absorbs 90 & 95% of airborne sound.
  • Unique visco-elasctic properties of wool assist in the conversion of sound energy to heat
  • The fibrous nature of a wool fiber means that, unlike many other materials, wool products can reduce airborne sound, surface noise and sound transmission all at the same time.
