Roca o vidrio fundidos hilados en paneles A1: el aislamiento incombustible por defecto.
También llamado: lana de roca · stone wool · glass wool
Lana mineral 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 Lana mineral 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.
Introducción profunda
Lana mineral (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.
Lana mineral 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 Lana mineral as a system: mill route, coatings, tests and the cavity it sits in.
Conductivity note: λ ~0.032–0.040 W/m·K typical batts. Insulation score 86/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Slag wool 19th c.; glass wool 1930s, US / Germany / Denmark. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: polyurethane-foam.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 58/100. Ask which scrap, which certificate, which year.
