Mineral Wool Insulation
In many ways, mineral wool is a superior insulation product. It has a higher R-value per inch compared to fiberglass, about a 22-37% higher R-value. It contains 70% recycled material, making it a greener product than fiberglass at 20-30% recycled material..
While termites don't actually eat the material used in insulation, they can easily tunnel through it, negating its energy-saving benefits.
Exposure to fiberglass can cause irritation in the eyes, nose, or throat. It may also cause itching and irritation when the fibers get stuck in the skin.
