Historically batts were made with toxic bonding agents necessary to create a low-cost insulating product with some ability to maintain shape. 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. This greatly reduces the net embodied energy in their production process as no high heat is required. Their batts are produced employing a mechanically-driven needle punch. As a result, they are malleable, not rigid or difficult to manipulate. Unlike other forms of insulation, Havelock Wool batts are easy to handle. They do not require protective clothing or safety equipment like respirators, gloves or heavy clothing to install: they are safe to the touch. The perfect insulation for a healthy space.
