Mineral wool in 1990s: EN 13162 · 509

Melted rock or glass spun into A1 batts — the default non-combustible insulation of codes. Mineral wool is one of 32 materials in this atlas, grouped under thermal: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue. Scores compare Mineral wool with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number. Mineral wool (Ca-Mg-Al silicates / soda-lime glass fibres) is a family of grades whose density 20–150 kg/m³ products, heat band softens ~1000 °C class (stone), and fire letter A1.

Mineral wool is sold as grades, not as a single substance. Chemistry Ca-Mg-Al silicates / soda-lime glass fibres, density 20–150 kg/m³ products, heat band softens ~1000 °C class (stone). This atlas treats Mineral wool as a system: mill route, coatings, tests and the cavity it sits in.
