Polyurethane foam in 1987: Montreal Protocol
Read the condition on Polyurethane foam before the nickname. Year 1987, line “Montreal Protocol,” figure 0. DFT, moisture meters and compression of batts are quality tools, not bureaucracy.
This atlas treats Polyurethane foam as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: λ ~0.022–0.028 W/m·K (aged PIR boards, bands). Insulation score 88/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: typically E–B with facers; not A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Otto Bayer 1937; fridge foam 1950s, Germany. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: mineral-wool. Circularity mark 32/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Polyurethane foam honest.
The coating that sometimes protects foam cores. FR fibre vs FR foam — different jobs. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation. Declared performance after blowing-agent or moisture drift. The zone where heat or chemistry changes the datasheet.
The label keeps Polyurethane foam, 1987, and 0. “Montreal Protocol” is the condition on the figure.1987
