Aerogel in 2010s: EN 13501 blankets · 402
amily of grades whose density ~0.003–0.15 g/cm³, heat band silica sinters; organic aerogels burn, and fire let Scores compare Aerogel with the rest of the atlas on strength, heat, fire behaviour, insulation, workability a Read the condition on Aerogel before the nickname. Year 2010s, line “EN 13501 blankets,” figure 13501. TEOS chemistry, supercritical drying cost. A material is what it is made of, the condition it survives, and where it goes afterward. Aerogel under “EN 13501 blankets” in 2010s should say which, with 13501 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
Scores compare Aerogel 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.
Aerogel (SiO2 network + >90% air) is a family of grades whose density ~0.003–0.15 g/cm³, heat band silica sinters; organic aerogels burn, and fire letter silica A1; polymer aerogels not. Aerogel is sold as grades, not as a single substance. Chemistry SiO2 network + >90% air, density ~0.003–0.15 g/cm³, heat band silica sinters; organic aerogels burn.
This atlas treats Aerogel as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: silica blankets ~0.015–0.025 W/m·K class. Insulation score 98/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: silica A1; polymer aerogels not. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
The label keeps Aerogel, 2010s, and 13501. “EN 13501 blankets” is the condition on the figure.2010s
