Process energy / dust
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Vacuum insulated panel · A sealed vacuum sandwich — λ around 0.004–0.008 W/m·K until the envelope leaks.
Darker cells mean a higher score for this topic on that metric.

Declared reaction class in this atlas: system-dependent; core often A1-ish, skins not. Assemblies still need resistance tests.
Thermal mark 99/100 versus the atlas. Conductivity note: centre-of-panel λ ~0.004–0.008 (declared bands).
150–250 kg/m³ panels
Origin story: Dewar 1892 idea; building VIPs 1990s– (Scotland / Germany / Japan).
Circularity mark 40/100 — editorial, route-specific.

Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class system-dependent; core often A1-ish, skins not is reaction language unless an assembly test is cited.
Mills, fibres, isocyanates, metal fume or silica — name the actual agent.
Corrosion, moisture, UV or creep silently retire sections.
Smoke, drip, fibres or toxicants depend on chemistry.
Handling injuries are more common than brochure failures.
The wrong grade is the most expensive hazard.

Assemblies (EI, R, Type X) are not implied by the material letter.
EN 13501, ASTM E84, ISO 5660, KS F 2271 — they do not equal each other.
Clothing FR and steel R-ratings are different professions.
Primary production is energy-heavy; ask for a route, not a slogan.
Additives, dusts and processing aids (not always the polymer backbone) drive regulation.
Process water, leachate or moisture swelling.
Sortability beats theoretical recyclability.
Grade mix-ups scrap lots.
Fibres, isocyanates, UV, sharp edges — not a generic “chemicals” pictogram.
Coatings and cavities change the letter.
Installation is in the specification.
Codes move. Recheck KS, JIS, EN, NFPA and IBC editions for the job’s jurisdiction.
Melted rock or glass spun into A1 batts — the default non-combustible insulation of codes.
Overall 69 🧽The low-λ organic foam of fridges and buildings — excellent insulation, a fire design problem unless PIR and coverings are honest.
Overall 46 🕯️Latent-heat packets that flatten temperature swings — not a substitute for λ insulation, a complement.
