Introducing Havelock Wool: A Truly Sustainable Insulation


In the green building world we sometimes take time, effort, and research to replicate natural processes. Bill McDonaugh puts this eloquently when he notes we should create objects that aspire to the performance abilities and services of trees:

What if our homes and workplaces were like trees, living organisms participating productively in their surroundings? Imagine a building, enmeshed in the landscape, that harvests the energy of the sun, sequesters carbon and makes oxygen...

The best case scenario for the things we create and put out in the world, we aim toward biomimicry in order to mirror the already amazing effects of natural materials. And sometimes you just have to say, we are not going to do any better than this, and use that natural material as it is. That summarizes a key reason 475 is partnering with Havelock Wool. We focus on building healthy and safe buildings free from mold and rot, and wool insulation manages to be a highly effective solution toward those ends, without the aid of additives, chemical processes, or binding agents.



A message from Havelock Wool owner / founder, and wool services evangelist, Andrew Legge:

Wool is one of the oldest insulation’s we know of. Its usage has diminished simultaneously to the conversant and never-ending proliferation of synthetics. In other parts of the world, sheep (and wool) are a more significant component of GDP thus such a move has been muted whilst alternative usages sought. Accordingly, sheep’s wool insulation is quite common in Australia, New Zealand, the UK and various parts of Europe.

To further this sensible cause here in the US we are greatly appreciative of a recent collaboration with 475, which will allow for a natural, high-integrity fiber to enter the world of high performance building.

The US insulation market is continually dominated by products that are either not good for us or are mildly better than those we have become accustom to using. In either case, there is now a viable alternative that is based on one simple reality: the extremely high integrity of a wool fiber.

It is scientifically understood that wool manages moisture against 65% relative humidity, irreversibly bonds with formaldehyde, nitrogen oxide and sulfur dioxide, and the trade is responsible for the sequestration of


some 525,000 tons of pure, atmosphere-derived carbon. It is also entirely renewable and sustainable in its creation, a great insulator that has evolved over thousands of years, and compostable at the end of an extended useful life. These claims are fact, not conjecture or marketing speak.

Havelock Wool is sourced in New Zealand and manufactured in the USA. Our products are fully tested, conform to the building code and are available in both batts and loose-fill.
