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

Numbers below are bands used by working engineers, not live quotes. Tensile note: not a structural material — a semiconductor film.
Fire performance in this atlas is editorial. Real projects need the assembly report.
Mechanical
Stiffness
Modulus follows chemistry and orientation — not the marketing nickname.
Toughness
Crack growth, not peak stress, retires most real parts.
Fatigue / creep
Cyclic and time-dependent damage dominate certificates issued on static coupons.
Hardness / hand
Indentation, drape or compressive class — whichever the trade actually measures.
Thermal
Conductivity
modest; not an insulator product — Perovskite (PV) is not a substitute for a dedicated λ layer.
Service temperature
Melting / softening / decomposition band: soft lattices; heat-sensitive.
Expansion
Joints and clearances must follow the expansion class of Perovskite (PV), not of steel-by-habit.
Thermal mass
Density thin-film sets how fast a section changes temperature.
Ageing of λ
Foams, VIPs and moist batts drift; quote aged values.
Electrical
Conductor or dielectric
Perovskite (PV) is generally a dielectric or semiconductor film, not building wire.
Static / EMI
Fillers and moisture change resistivity more than brochures admit.
Standards language
IACS, volume resistivity or dielectric strength — pick the quantity the job uses.
Fire
Reaction to fire
Typical declared class: device, not a building class. This is not a universal passport.
Resistance vs reaction
Euroclass is reaction. EI/R ratings are assemblies — boards, coats, cavities.
Melt-drip / char
Perovskite (PV) can burn or drip; do not treat it as A1 without a system test.
Smoke / toxicity
CO, HCN, HF or fibres — the species depend on chemistry. Name the test (ISO 5659, EN 45545, NFPA 1971).
If a salesperson quotes a single “safety score”, ask which standard, which thickness, which year.
