Abstract
A method of producing a sandwich panel core of mineral wool fibres from a cured mineral fibre product includes the steps of providing a cured mineral fibre product with a dual density having a top layer with mineral fibres with a first density and a base layer having mineral fibres with a second density, the second density is at least two times lower than said first density. The top layer and the base layer have different fibre orientations. Further steps including cutting the mineral fibre product into a plurality of lamellae, rotating the lamellae 90 degrees, and re-joining the lamellae so that the top layers with the first density are vertically oriented.

A method of producing a sandwich panel core of mineral wool fibres from a cured mineral fibre product, said method comprising the steps of:
- providing a cured mineral fibre product with a dual density comprising a top layer comprising mineral fibres with a first density and a base layer comprising mineral fibres with a second density, said second density being at least two times lower than said first density, and said top layer and said base layer having different fibre orientations;
- cutting said mineral fibre product into a plurality of lamellae;
- rotating each of said lamellae 90 degrees;
- and
- re-joining said lamellae so that said top layers with said first density are vertically oriented.
