01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become Mineralwolle.
Mineralwolle · Geschmolzenes Gestein oder Glas als A1-Matten — der unbrennbare Standard.
Making Mineralwolle is a chain: feedstock, conversion (Slag wool 19th c.; glass wool 1930s), forming, heat, finish, install.

Slag wool 19th c.; glass wool 1930s
Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
Coatings, sizings, facers, galvanizing, anodising, painting.
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
Virgin route around US / Germany / Denmark.
Recycling exists but quality or energy often disappoints.
High-spec grades leave the commodity mill.
Coatings, sprays, casts — the factory is sometimes a jobsite.
Feedstock to installed product.
Energy in, class out.
Melting/softening softens ~1000 °C class (stone); conductivity λ ~0.032–0.040 W/m·K typical batts.
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Mineralwolle.
Fire class A1 is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
Organischer Niedrig-λ-Schaum für Kühlschrank und Bau. Brandschutz braucht PIR und Bekleidung.
