A method of sizing insulating glass fibers, comprising: preparing glass fibers by a high temperature aerodynamic procedure in which glass fibers are drawn out by a gas current and collected in a hood; spraying a size diluted in water onto said glass fibers in said collection hood, said size consisting essentially of an epoxy resin, an amino hardening agent and, as additives, 0.1 to 2.0% of a silane and 0 to 15% of a mineral oil, each calculated on 100 parts of dry resin, wherein said epoxy resin is a condensation product of epichlorohydrin and bisphenol A having a polymerization index n of less than 1 and the equivalent molar mass of the hardening agent is less than 100 g and said size is free of formaldehyde and components which release formaldehyde when baked; and recovering a sized insulating glass fiber product.
