We source our wool from New Zealand due to their expertise in cleaning and grading wool for professional building products. The U.S. lacks the infrastructure and consistent quality needed for our high standards, as New Zealand achieves far lower vegetable matter content during processing. While we continue to explore domestic options, none have met the rigorous standards required for our machinery and customer expectations.

Wool is naturally hypoallergenic, and reactions are often mistaken for irritation caused by coarse wool fibers used decades ago. Modern wools like merino are commonly worn without issue, and Havelock Wool has been installed in numerous sensitive environments without problems. If concerns persist, testing for reactions is recommended.

Havelock Wool is fire-resistant and conforms to Class A standards of the ASTM E84 test, which evaluates flame spread and smoke development. Wool's natural composition, with high nitrogen and water content, makes it self-extinguishing and resistant to combustion below 1,100°F. This ensures compliance with building codes and reduces fire risks, producing less smoke and no harmful drips, making it ideal for insulation and other fire-sensitive applications.

Havelock Wool contains less than 1% boric acid by weight to deter all insects, including moths, with zero reported infestations across over 40,000 projects. Boric acid is a naturally occurring compound deemed safe by the EPA, with no evidence of toxicity in common applications or inhalation scenarios. Our wool is also thoroughly washed and scoured to ensure purity.

Our wool may have a natural, mild scent when first unpacked, but it will fade quickly. To help it air out, simply open the box and allow the wool to expand for a day or two. Once aired, the wool not only becomes odor-free but also acts as a natural odor neutralizer in your space.

At Havelock Wool, we believe insulation should be both high-performing and sustainable. Wool is a natural, renewable fiber with incredible properties—it regulates temperature, resists fire, absorbs sound, and improves air quality by neutralizing toxins. Unlike synthetic materials, wool is non-toxic, biodegradable, and safer for homes, people, and the planet. It's simply a better choice for healthier, more sustainable living.

We source our wool exclusively from New Zealand, a global leader in wool production, where farmers follow rigorous standards for quality and sustainability. The wool is carefully cleaned, graded, and processed to meet our high-performance standards. By working closely with suppliers, we ensure our wool is ethically sourced and aligns with our commitment to environmental stewardship.

Havelock Wool combines cutting-edge technology with the timeless benefits of wool to deliver insulation that outperforms traditional options. Our product is non-toxic, fire-resistant, and eco-friendly, offering superior performance without compromising health or sustainability. With a focus on education and transparency, we empower customers to make informed decisions, ensuring a better-built environment for everyone.
