Fire requires three components: ignition, oxygen, and fuel. Greenix Panels have no “air” within the solid core of the insulation. The fire cannot “run up the wall” cavity, as is the case with traditional stud construction. Polyurethane foam does not melt. The Greenix Panel system has passed every standard fire test that is required of wood-based or “Type V” construction. To the surprise of some building researchers, data from extensive laboratory fire testing as well as reports from actual house fires indicates that Greenix Panel made structures tend to be more resistant to house fires than standard stud structures.
We test our panels to the American Society for Testing and Materials (ASTM) E84-04 “Standard Test Method for Surface Burning Characteristics of Building Materials” for smoke spread and flame spread. Greenix Panels have a Class 1 foam core. The foam components are formulated to have a flame spread of less than 25 units and smoke spread of less than 400 units.
