A fibrous insulation has insulation fibers () with a fungicide in a dispersed additive affixed to the fibers (), and a method of making a fibrous insulation by dispersing a fungicide and a dispersed additive on the fibers () followed by affixing the dispersed additive on the fibers (). The method produces thermal, acoustic, duct liner or board insulation either as loose fill insulation or as an insulation mat.

Fibrous insulation with fungicide

A system for blowing loose-fill insulation includes a loose-fill blowing machine including a discharge hose. An ionizer is disposed in the flow path of the insulation through the discharge hose, wherein the ionizer reduces the static charge developed on the insulation prior to discharge thereof. A method of reducing static charge developed on loose-fill insulation during blowing is also provided and includes the step of ionizing the insulation in the flow path of the insulation while the insulation is being discharged to reduce the static charge.
