Oregon Shepherd’s PermaLoft

June 21, 2011

Made from natural and sustainable sheep wool, PermaLoft might be the only loose fill, blown-in wool insulation in the world, the company claims. It reduces heating and cooling costs by eliminating voids and air pockets common with other materials and does not require protective clothing for installation.
