Method for preparing an insulating product based on wool, in particular mineral wool

A method for preparing a wool-comprising insulating product, the method comprising:

• aerating inside a device, the device comprising a chamber and a turbulent gaseous flow generator,
• wherein the aerating comprises introducing a stream of carrier gas into the chamber and subjecting a wool in nodule or flake form to a turbulent gaseous flow of the carrier gas, with entrainment of the wool in the turbulent gaseous flow in a direction A and in a direction B, the direction B being opposite to the direction A, such that within the chamber, there is at least one plane perpendicular to the direction A, in which wool entrained in the direction A crosses wool entrained in the direction B, and
• wherein the turbulent gaseous flow comprises a first turbulent gaseous flow in the direction A and a second turbulent gaseous flow in the direction B.
