Sonya's Kitchen: sheep's wool

When insulating a stick frame house, wool is my go-to. Not only does it outperform conventional insulation in categories that people know to look for, like R-value (thermal performance), fire and pest resistance, and acoustic performance, it outperforms in areas that people don't even know to look for, like ethical production, improving air quality by neutralizing toxins, environmental sustainable production and lifecycle, and non-toxicity to producers, installers, occupants, and future generations.

Also, it's a joy to handle. Like playing with big cozy stuffed animals.
