Exterior applications: must be covered with weatherproof facing. Extend the foam 4 inches past the walls, so that you can add foam to the walls later and tie it in to the roof. 1. Rigid foam board is more expensive than batt insulation, but for good reason because the R-values of foam board are much higher. Cost-wise, spray foam roofs are comparable to many other commercial roofing systems, however, they are significantly more expensive than standard roof coating systems. R-Value is a measure of insulation's ability to resist heat traveling through it. Model # 90014713. Extruded polystyrene (XPS) Easily recognized by its blue, green, or pink color.
