1. A method for manufacturing an insulation product comprising mineral wool bound by an organic binder, comprising the following successive steps:
(a) humidifying a mineral wool to provide a humidified mineral wool that comprises from 0.2 to 1.5% by weight of water;
(b) placing the humidified mineral wool that comprises from 0.2 to 1.5% by weight of water in contact with particles of binder comprising a mixture of thermosetting reagents to provide a mixture of mineral wool and binder particles;
(c) shaping the mixture of mineral wool and binder particles to provide a shaped mixture; and
(d) heating the shaped mixture to a temperature and for a period sufficient to allow condensation of the reagents and the formation of the insulation product comprising mineral wool bound by the organic binder.
