Frequently Asked Questions


Does sheep wool insulation work as well as man-made products?

Better! Sheep wool insulation is more efficient than man-made products like mineral wool.

BACK TO TOP


Is sheep wool insulation sustainable?

We believe it is the most sustainable insulation product available commercially. Sheep are shorn yearly for their wool at the appropriate time of year, and typically the coarsest and darkest available are used-the insulation is thus essentially made from a waste product. Also, only a fraction of the energy required to make man-made insulation is required to make sheep wool insulation.

How easy is it to install?

Very. The sheep wool material is made to fit into existing blow-in insulation equipment.

BACK TO TOP


Is sheep wool insulation resistant to pests?

Yes. The wool is treated with Borax, a non-toxic natural mineral used for this purpose in many natural materials.

Does sheep wool insulation burn?

Wool is naturally fire-resistant. This is why, in the past, wool was used for flash fire protection for firemen.

Why is wool insulation so effective in dealing with moisture?

Wool can absorb up to 40% of its own weight in moisture and still remain dry. As it absorbs moisture it warms up, reducing the risk of condensation. Conversely, as the moisture evaporates from the wool it cools down. Less energy is required for heating and cooling. Sheep wool insulation is not susceptible to mold like man-made products.

BACK TO TOP


How long will sheep wool insulation last?

Significantly longer than many commercially available man-made materials. Wool insulation retains its loft and performance for 50 years and beyond-compare to man-made products that require "topping" every ten years.

Does sheep wool insulation have good acoustic performance?

Sheep wool is denser than fiberglass, and performs particularly well in dampening airborne sound.

Why is sheep wool insulation a good fit for older properties?

Older properties often don't have vapor barriers. Man-made insulation is thus even more susceptible to condensation, resulting in mold, timber rot etc. Sheep wool's natural moisture wicking properties make it the ideal solution to this problem.
