What is Wool Insulation?

Healthy, high-performance insulation made from 100% wool.

Insulation Solutions is a preferred installer of Havelock Wool. Havelock Wool is used in residential and commercial construction as thermal and acoustic insulation. It can be used in open attic areas, enclosed walls, floors, ceilings, basements and crawl spaces.

The wool comes from New Zealand because a wool is a significant industry in that country. They are the leaders with the science, engineering, and infrastructure to properly clean wool used as a professional building product. 

Havelock processes the raw wool material thru a production line of high tolerance machines to make a finished end product with a guarantee above and beyond other manufacturers.

The Many Advantages of Wool Insulation

Moisture Management

Wool insulation actively manages moisture, helping keep your house or business dry and free of mold and mildew.

Expand to Learn More About Moisture Management

Wool fibers inherently manage moisture, absorbing and releasing it against 65% relative humidity. This allows for condensation to be minimized as wool generates heat from energy, thus making it warm when wet.

Equally important, wool is a keratin and therefore will not support the growth of mold. These characteristics, on their own, make wool an outperformer as an insulator; on a relative basis it is second to none.

Air Quality

Wool is devoid of harmful chemicals and actually helps absorb them! Wool fiber can absorb and regulate indoor pollutants.

Expand to Learn More About Air Quality

The inherent construct of a wool fiber traps air and in turn insulates your home. It also does much more.

Wool insulation removes dust particles which may contain harmful chemicals such as formaldehyde, nitrogen oxide and sulphur dioxide. No other type of insulation offers these unique capabilities. 

Sound Absorption

Havelock Wool excels at absorbing sound and reducing unwanted noise. All this makes your living space a more pleasant place to be.

Expand to Learn More About Sound Absorption

Visco-elastic properties of a wool fiber assist in the conversion of sound energy to heat. What’s more, a wool fiber is unique in its ability to simultaneously reduce air born sound, surface noise and sound transmission.

Insulation Performance

Havelock Wool's measure of performance is an impressive R Value Per Inch of 3.6 for Batts and 4.3 for Blown-In.

Expand to Learn More About R-Value & Performance

R-value denotes resistance to heat flow. The higher an insulation’s R-value, the greater its insulating power. Sheep wool insulation R-value equals or often surpasses that of other insulation materials.

The extremely high integrity of a wool fiber allows it to outperform the synthetic competition, while decreasing impact on the environment.

Highly resistant

Wool insulation is highly resistant to negative enviromental factors like fire, mold, mildew, and compresssion.

Expand to Learn More About Resistance

Havelock Wool conforms to Class A of the building code for flame spread and smoke development. Wool has a high nitrogen and water content so it needs higher levels of oxygen to burn than the surrounding environment provides.

Havelock Wool is a protein-based keratin meaning it resists mold and mildew to avoid an unhealthy living environment. And wool actively manages relative humidity. The interior of the wool fiber is actually hygroscopic meaning it has a high moisture buffering capacity.

Havelock Wool insulation was also evaluated to be highly resistant to compression at >35 micron.


Havelock Wool is renewable, sustainable, biodegradable and compostable. Its overall carbon footprint is extremely low.

Expand to Learn More About Sustainability

Havelock Wool is a truly sustainable building material, from its production to the end of its life. Overall carbon emissions stack up extremely favorably compared to any other insulation material. The raw material is not petrochemical-based and the Havelock production process is not energy-intensive.

Wool is biodegradable and compostable meaning wool can be placed back in the earth where it will break down on its own and actually fertilize the soil.

Questions? Want to Talk to an Wool Insulation Expert?

Havelock sources only the best fibers for use in our wool insulation. The fibers are a certain dynamic, sheared from a specific breed of sheep best suited for insulation.

Havelock processes high quality wool fibers through their proprietary manufacturing process. This yields a uniform, high-performance, long-lasting product.


Wool is an Effective Insulator

Wool Provides a Sustainable, Non-Toxic, High Performance Insulation Alternative

Wool’s natural structure makes it incredibly effective as an insulator. Each wool fiber is composed of protein molecules (keratin) organized into five follicles. These fibers effectively trap air, moisture and harmful chemicals. Using wool as insulation actually helps keep your home warm in the winter and cool in the summer, while improving indoor air quality.

What Makes Wool So Good?

Wool is composed of proteins known as keratins.

A wool fiber’s chemical complexity makes it resilient and elastic.

Each fiber can be bent on itself over 20,000 times.

Wool’s scaled structure allows for absorption and retention of airborne dust.

All natural – wool insulation is entirely renewable and sustainable.

Wool is biodegradable and compostable.

No off-gassing – natural characteristics make our insulation devoid of harmful chemicals.

Installs easily – blown-in and batts are installed like other mediums but with no protection required.
