A method and an apparatus for recycling glass fibre material are disclosed, as well as products fabricated by the disclosed method. The invention deals with mechanically transforming glass fibre material extracted from a composite material in a first form to glass fibre material in a second form. The glass fibre material is further treated into a third form, the glass fibre material is further treated into a third form, the glass fibre material in the third form being suitable for insulation material. The glass fibre in the third form may be such insulation material as wool or cotton-like insulation material, insulation bats, insulation rolls, insulation pellets, insulation panels, such as curved panels and self-sustaining panels.
