Quick answers
Is Perovskite (PV) non-combustible?
Declared reaction class in this atlas: device, not a building class. Assemblies still need resistance tests.
Does Perovskite (PV) insulate?
Thermal mark 8/100 versus the atlas. Conductivity note: modest; not an insulator product.
What is the density band?
thin-film
How is it made?
Origin story: Miyasaka 2009 DSSC; 2012 solid-state jump (Japan / Oxford / Korea).
Can it be recycled?
Circularity mark 40/100 — editorial, route-specific.
Typical melting or failure heat?
soft lattices; heat-sensitive

Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class device, not a building class is reaction language unless an assembly test is cited.
Hazards
In service
Corrosion, moisture, UV or creep silently retire sections.
Fire products
Smoke, drip, fibres or toxicants depend on chemistry.
Cut / puncture
Handling injuries are more common than brochure failures.
Mis-specification
The wrong grade is the most expensive hazard.
Fire class
Reaction
device, not a building class
Resistance
Assemblies (EI, R, Type X) are not implied by the material letter.
Test families
EN 13501, ASTM E84, ISO 5660, KS F 2271 — they do not equal each other.
People vs structure
Clothing FR and steel R-ratings are different professions.
Environment
Carbon / energy
Primary production is energy-heavy; ask for a route, not a slogan.
Toxics / fibres
Additives, dusts and processing aids (not always the polymer backbone) drive regulation.
Water
Process water, leachate or moisture swelling.
End of life
Sortability beats theoretical recyclability.
Handling
Store dry and labelled
Grade mix-ups scrap lots.
PPE for the actual agent
Fibres, isocyanates, UV, sharp edges — not a generic “chemicals” pictogram.
Do not improvise fire class
Coatings and cavities change the letter.
Follow the WPS / DFT / compression
Installation is in the specification.
Codes move. Recheck KS, JIS, EN, NFPA and IBC editions for the job’s jurisdiction.

Carbon fibre
Polymer-derived filaments with graphite-like sheets — aero, bikes and a fire story that is about the resin, not the fibre.

A one-atom carbon sheet — Nobel-era physics, composites hype, and a few honest electronics and barrier uses.
Overall 50 ☁️Aerogel
A nanoscale silica sponge — among the lowest solid λ values, fragile unless blanketed, and A1 when purely inorganic.
