Abstract
A process is for insulating an appliance, in particular a three-dimensional appliance likely in particular to be exposed to high temperatures, such as a domestic oven. The appliance has one or more internal spaces to be insulated. Flakes and/or nodules of wool(s) and/or fibers, in particular mineral wool(s) and/or fibers, are blown into the space(s) to be insulated without adding binder or water.
Claims12
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.
