A process for producing a molding from glass fiber material and/or mineral fiber material with an inorganic binder, comprising the steps of:
- providing a mold to shape the glass fiber material and/or mineral fiber material to form the molding;
- introducing the glass fiber material and/or mineral fiber material and an inorganic binder into the mold;
- curing the inorganic binder by subjecting it to electromagnetic radiation within a range from 1×104 Hz to 4×1014 Hz to form a cured molding;
- removing the cured molding from the mold,
- wherein the mold is transparent at least in subregions to the electromagnetic radiation for curing, and wherein the inorganic binder is curable with the electromagnetic radiation.
