Abstract

A process for making a fibrous product using a binder based on a formaldehyde-containing resin and especially for making fiberglass insulation products, and to the fibrous products themselves, wherein the fibrous product [11] is placed in a mass transfer relationship with a formaldehyde scavenger, such as by having a backing sheet [12] affixed thereto arid the backing sheet [12] is coated or impregnated with a formaldehyde scavenger composition, or by isolating the insulation product in an enclosed space with a formaldehyde scavenger, with the result that the fibrous product [11] exhibits a reduced level of formaldehyde emission.
