Havelock Wool batts are comprised of 100% wool for a healthy home. Unlike other options, there is no synthetic mix in their products, which means there is no glue, no formaldehyde, and no harmful chemicals of any sort. They do not require protective clothing or safety equipment like respirators, gloves or heavy clothing to install: they are safe to the touch.
