Just like other insulation products, except you don’t need gloves, a mask or protective clothing. Wool batts fit into cavities like other insulation and our blown-in product (loose fill) is blown behind an insulation retainer mesh using an insulation removal vacuum which virtually every installer has in their possession. You can also find them at any tool rental center. Please see below for a complete overview of batt and blown-in (loose fill) installation. Our YouTube channel also has these videos separated out…. blown-in installation and batt installation.
