WebOct 22, 2015 · The fire must still be hot enough to then transfers enough heat to the inside layer (another EPS foam layer) which also must be consumed before transferring enough heat to ignite the drywall or interior finish. BuildBlock ICFs are tested by Intertek and the wall will last 4+ hours. Untreated EPS foam burns at 650° to 700°F with a flame source. WebPUR foams are essentially made by reacting a “polyol” component and an “iso” component in which the OH groups of the polyol component chemically balance the NCO groups of the iso component and form urethane linkages. In PIR foams, the iso components react with each other in trimerization reactions to form isocyanurates.
