Why You Should Specify & Recommend Wool Insulation

Insulation has been overlooked in the built environment for far too long. We assume it’s only because there hasn’t been a product worth talking about – now there is.

We all have a responsibility to use healthy, safe, high-performance materials whenever possible. Wool is unlike any other insulation medium available on the market.

You’re driving industry change when you combine wool insulation to create thermally efficient air-tight enclosures that also address inherent vapor drive.

Hear what Mike Strong from Charles Pankow Builders has to say about Havelock Wool

As a proud member of the Embodied Carbon Network we are increasingly aware of the role the built environment plays in what is none other than a global problem. For perspective, at current rates another New York City is built every 35 days. The energy employed in the construction is important as is the operational costs that follow. Given the sheer scale, equally important is material selection and its subsequent performance, followed by what is entailed in discarding those materials. The carbon question and potential solutions are a gargantuan undertaking; however, there are options available for consideration today. In our (insulative) world the chart below makes those options clear. We are honored to be among them.

Insulation R-Value Map

The built environment is perhaps the single largest contributor to the outsized carbon footprint that humans account for. Yes – structures need to be more efficient, but not at the risk of utilizing building materials that produce grave side-effects.

Wool Insulation Benefits

Make the World Better One Structure at a Time

Consider the benefits of improving a building’s thermal efficiency, indoor air quality, moisture management, and sound absorption, while simultaneously making a commitment to sustainability and renewable resources.

We all have a responsibility to do better, which is why we’ve returned to nature for an elegant solution to a set of complex problems.

  • Wool insulation is your long-term insulation solution.
  • It is entirely renewable and sustainable.
  • Wool insulation has the lowest net embodied energy than any other medium available.
  • The wool trade is responsible for the sequestration of more than 500k tons of atmosphere-derived carbon each year.
  • Wool insulation is natural and high-performing.
  • There is no insulation medium available that offers passive air filtration.
  • Havelock Wool insulation produces no waste in production.
  • Wool insulation can be composted, if not reused, when the structure is repurposed.

Biomimicry – The design and production of materials, structures and systems that are modeled on biological entities and processes.

Instead of turning to synthetics and man-made products, sheep’s wool insulation employs the time tested functionality of nature. This is true biomimicry. By virtue of the arrangement of the fibers, natural wool insulation provides superior passive air filtration, natural moisture management and exceptional sound absorption.

Wool Insulation Applications

Our wool insulation is well suited for any residential or commercial application. We offer various products from wool insulation batts to loose fill wool insulation, all designed to solve thermal efficiency and insulation problems.
