Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an insulating product with which production cost is not augmented, and emission of ammonia is reduced in the production line.SOLUTION: This insulating product is based on mineral wool sized with a binder based on a phenol-formaldehyde resin, in which the binder comprises, as a mixture, 60-90 pts.wt. of phenol-formaldehyde resol having a free formaldehyde content of less than or equal to 25% by weight with respect to the dry weight of resin, obtained by condensation in a basic medium of phenol (P) and formaldehyde (F) in an F/P molar ratio of around 2.5 to 4 until the condensation product neutralized by sulfuric acid has water dilutability of greater than 500% and less than or equal to 1,500%, and 10 to 40 pts.wt. of urea. Use of such a sizing composition for producing insulating products, while reducing the emission of ammonia gas on the production line, is provided.
