 * <u>CAN / ULC S704-01 (CGSB 51-GP-21M)</u> applies to unfaced polyisocyanurate rigid insulation boards intended for applications where the continuous use surface temperature does not exceed +110&#176;C (+230&#176;F). This standard establishes one type (Type 4) and three classes (Class 1, 2 or 3) of polyisocyanurate insulation. The type is determined by the physical properties of the material and the class is determined by its surface burning characteristics.

This standard establishes four types (Type 1, 2, 3, or 4), four facing categories (Facing 1, 2, 3, or 4), and two surface burning characteristic classifications (surface burning characteristic &#8220;a&#8221; or &#8220;b&#8221;). The type is determined by the physical properties of the material, the facing is determined by the product the insulation is foamed between, and the surface burning characteristic is derived from the final product's flame spread classification. <i>RGC Guarantee Standards</i> require that polyisocyanurate insulation manufacturers clearly identify the manufacturing date on product labels.
