A 3-layer insulation material comprising
- a first fabric layer, a second fabric layer and a third fluted intermediate fabric layer between the first and the second fabric layers, the third fluted intermediate fabric layer being attached alternately to the first and the second fabric layer with longitudinal seams forming longitudinal bundle channels for insulation material, and
- an individual insulation material bundle inside each longitudinal bundle channel,
- wherein the longitudinal seams are laser welded seams and the first fabric layer and the second fabric layer are infrared radiation transparent fabric and the third fluted intermediate fabric layer is infrared radiation absorbing fabric.
A method for producing a 3-layer insulation material comprising the steps of:
- introducing a first fabric layer, a second fabric layer and a third fluted intermediate fabric layer between the first and the second fabric layers, the first fabric layer and the second fabric layer being infrared radiation transparent fabric and the third fluted intermediate fabric layer being infrared radiation absorbing fabric, and
- attaching the third fluted intermediate fabric layer alternately to the first fabric layer and the second fabric layer to form a plurality of longitudinal bundle channels, wherein
- the first fabric layer and the second fabric layer are attached to the third fluted intermediate fabric layer by laser welding.
