Blowable insulation material with enhanced durability and water repellency

A blowable insulation material comprising natural fibers and short cut synthetic fibers or fiber balls. The natural fibers and short cut synthetic fibers or fiber balls are individually treated with a water repellent to impart water repellency to the fibers, and later aerodynamically blended together. The water repellent fibers constitute a part or most of the blowable insulation material, thus enhancing the durability of the structure as well as water repellency, which may be advantageous during washing or laundering.
