18 Claims

1. A method for manufacturing an insulation product comprising mineral wool bound by an organic binder, the method comprising the following successive steps:

(a) providing mineral wool at room temperature;

(b) applying, to the mineral wool, an aqueous thermosetting binder composition;

(c) drying the mineral wool impregnated with the aqueous thermosetting binder composition, to obtain thermosetting mineral wool;

(d) shaping the thermosetting mineral wool; and

(e) heating the shaped thermosetting mineral wool at a temperature for long enough to enable the constituents of the binder to be condensed and an insoluble binder to be formed.
