Abstract

According to one embodiment, a polyisocyanurate foam board is described. The foam board includes a polyisocyanurate core that is produced from: an isocyanate, a polyol, and a phosphorous containing non-halogenated fire retardant. The foam board also includes a facer material that is applied to at least one surface of the polyisocyanurate core. The polyisocyanurate core has an isocyanate index greater than about 200 and is able to forms a sufficiently stable char when exposed to flame conditions to enable the polyisocyanurate core to pass the ASTM E-84 test. The foam board has an initial R-value of at least 6.40 and exhibits an ASTM E1354-11b test performance that is equivalent with or better than a similar foam board having a halogenated fire retardant, such as tris(2-chloroisopropyl)phosphate (TCPP).
