Wool insulation

Instead of opting for traditional fiberglass insulation that can release minute particles into the air that subsequently cause lung and respiratory problems, sheep wool has several added benefits while also delivering optimum thermal performance. The fibers in sheep wool can absorb and exude moisture without altering the energy efficiency performance. This hygroscopic feature means that your home will stay well insulated while also benefitting from a natural air dehumidifying process that sheep wool offers. Some wool insulation products can absorb up to 35% of their weight in moisture without reducing their insulation abilities. Wool insulation can also reduce noise levels, thus acting as an acoustic insulator for people who live next door to raucous neighbors or loud highways.

Havelock Wool

Havelock Wool manufactures high-performance, all-natural wool insulation using sheep's wool from New Zealand. Their processing involves the lowest net embodied energy in the industry while making insulation products that meet or exceed industry standards. Installation doesn't require protective clothing. From Reno, Nevada, they're always looking to work with those who appreciate the value of alternative building products and a healthier, more sustainable ecosystem.

Wool carpeting

Another common use of sheep wool in the home is for carpeting alternatives. Whereas most carpets in America´s homes are made from nonrenewable synthetic fibers such as nylon and polypropylene, wool carpets have been made for thousands of years. Unlike other commercial and synthetic carpets, wool carpets and rugs can actually purify indoor air quality instead of releasing potentially dangerous VOCs. The natural crimp in wool fiber will prevent dirt, dust mites, and other allergens from penetrating deeply into the fabric. It can also absorb and hold other common indoor contaminants such as nitrogen dioxide from gas appliances and sulfur dioxide malfunctioning chimneys.

As we mentioned above, wool can absorb water vapor while simultaneously repelling spills, helping regulate humidity levels in homes while also naturally deterring stains. Because sheep wool contains lanolin, it will not support combustion and can protect your home from fires.

One company specializing in non-toxic carpet alternatives is Earth Weave. Their Bio-Floor™ Carpet models are made from 100% undyed and untreated wool. The primary backing of this carpet option is made from a blend of cotton and hemp, both of which are also natural materials. Even though their carpets contain no artificial or synthetic dies, there is a wide range of earth tone colors that will fit in with almost any interior design palette.
