On a current Wednesday afternoon at a 67,000-square-foot manufacturing facility in Reno, Nevada, a big machine moved fluffy, off-white material by means of a series of drum rollers. The substance was applied to thick insulation boards created of a material not usually discovered inside the walls of homes: wool.
“Hot, cold, warm, dry – wool does it all,” mentioned Andrew Legg, founder and managing companion of Havelock Wool.

The firm manufactures insulation solutions totally from sheep’s wool. Legge began the firm in response to the lack of healthier and sustainable alternatives in the insulation market.
“As an insulator, we’d like to say that the evolution occurred in nature’s R&D division — not in some lab producing a synthetic fiber that is just not going to be fantastic from the begin,” Legge mentioned.
According to the Environmental Operating Group, a nonprofit organization that advocates for environmental well being, generally utilized supplies such as fiberglass and spray foam can include toxic chemical compounds that can pose a well being threat to installers. Legge mentioned that is pushing a lot more property owners to say, “Wait, I do not want that.”
“And if we do our job,” he continued, “then when they go searching for an option, they come across us.”
And several folks did through the pandemic. Havelock Wool’s sales quadrupled through the very first year of COVID-19 and are up one more 25% in 2021. Legge mentioned sales had been flat final year since production could not maintain up with demand.
One more firm attempting to capture these customers is Hempitecture. Primarily based in Ketchum, Idaho, Hempitecture tends to make insulation from hemp sourced from farmers in neighboring Montana. Mattie Mead, founder and CEO, mentioned sales have doubled year-more than-year given that he launched the organization in 2018.
“Customer sentiment towards sustainability is a large issue,” Mead mentioned. “The pandemic has improved awareness of how a great deal time we invest indoors.

Havelock Wool and Hempitecture are just two organizations attempting to get a piece of the sustainable developing supplies marketplace, which is estimated to be worth practically $81 billion. One more that caters to environmentally conscious customers is Denver-primarily based RavenWindow. It tends to make “sensible windows” that automatically darken when it really is hot to lower heat and glare and enable for maximum light and warmth when it really is cold, assisting property owners use much less power.
Nevertheless, organizations with environmentally friendly options attempting to obtain a foothold in the building sector face a quantity of challenges, mentioned John Freer, director of the Sustainable Constructing Technologies System at the University of Montana’s Missoula College.
1 of the most significant obstacles? Numerous performers are resistant to modify and can be intimidated by a new material or strategy.
“They know the material they are functioning with, they know what it charges, they know how extended it requires them to set up it, they know its longevity and they know the warranty on it,” Freer mentioned.
Meanwhile, several purchasers are place off by the costs of solutions like sustainable insulation, which can expense twice as a great deal as other kinds. Fiberglass panels, for instance, run among 30 cents and $1.50 per square foot, according to HomeAdvisor. Havelock Wool’s site lists its wool panels for among $1.50 and $two.25 per square metre.
Insulation is ordinarily much less than two% of the total expense of developing a dwelling, and the typical expense for a standard single-household dwelling is just more than $five,000, according to a 2019 report from the National Association of Household Builders.
Nevertheless, it can add thousands of dollars to a project, mentioned Daniel Fraiman, who builds multimillion-dollar houses about Lake Tahoe and Truckee, Calif.
“Price becomes an inhibitor to generating some of these solutions,” Fraiman mentioned. “They like the notion and they get attached to it early on, and then when we get into how a great deal it charges, it does not function.”
Fraiman mentioned consumers who pick to use sustainable insulation study the added benefits and study the well being dangers of other kinds, specially for installers.

Andrew Legge, founder and managing companion of Havelock Wool, stands subsequent to boxes of insulation solutions inside the company’s facility in Reno, Nev.
“Spray foam insulation is a single of the roughest solutions out there,” Fraiman mentioned. “Those guys are wearing spacesuits. I imply, they are in complete hazmat suits since these factors are lumpy.”
Back at Havelock Wool, waves of wool could be observed wafting by means of the air as workers donned the standard face masks bagged and boxed solutions. The firm does not add any synthetic additives or binders to the material, but does add a compact quantity of non-toxic boric acid to repel insects.
Standing in the center of the factory, Legge mentioned the firm will ramp up production later this year. He invested in new machinery so they could triple their processing capacity to a lot more than 16,000 pounds of wool per day.
“We’re properly aligned with what extended-term demand appears like and this shift in customer demand for greater, healthier, a lot more sustainable solutions,” Legge mentioned.
