This atlas treats Mineral wool as a system: mill route, coatings, tests and the cavity it sits in. Conductivit Read the condition on Mineral wool before the nickname. Year 1980s, line “Binder formaldehyde,” figure 0. After cladding fires, non-combustible insulation gained code weight.
This atlas treats Mineral wool 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. Circularity mark 58/100. Ask which scrap, which certificate, which year.
Related atlas entries, a short glossary, and three threads that keep Mineral wool honest. Lower λ, combustible unless protected. When service temperature exceeds stone wool. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation.
