1. A process for insulating an oven, the oven having one or more internal spaces, to be insulated, the process comprising:
blowing flakes and/or nodules of wool(s) and/or fibers into the space(s) to be insulated without adding binder or water,
wherein at least 50 wt. % of the flakes have a largest dimension in a range of from 5 to 25 mm,
wherein the flakes and/or nodules are made of glass or carbon or ceramic wool(s) or fibers, with a micronaire of less than 25 L/min, and/or are made of rock wool(s) or fibers, with a fasonaire of greater than 150 mmwc,
wherein the blowing gas pressure is in a range of from 12 to 45 kPa and/or in that the blowing flow rate is in a range of from 40 to 90 g/s,
wherein the flakes from an insulating layer with a density in a range of from 40 to 120 kg/m3, and
wherein the insulating layer takes a final shape without requiring a subsequent shaping.
