A composition includes glass fibers and a polyether antistatic agent. The polyether antistatic agent has a molecular weight of less than about 2000, or less than about 1000. Exemplary polyether antistatic agents include polyethylene glycol, polypropylene glycol, a glycerol polyether, and combinations thereof. The polyether antistatic agent has a viscosity of less than about 600 cSt at 75° F., or less than about 200 cSt at 75° F. The composition may further include a solvent for the polyether antistatic agent; the solvent may include one or more organic soluble electrolytes, water or a combination thereof. Exemplary organic soluble electrolytes include calcium acetate, lithium acetate, an amine acetate, sodium benzoate, and combinations thereof. The composition may be used in various insulation applications, including in an insulation batt, insulation roll, insulation board, insulation pipe or unbonded glass fiber insulation. Methods for making glass fibers for use in insulation and methods for installing unbonded glass fiber insulation are also described.
