What is the R-value of 2 Styrofoam?
STYROFOAM extruded polystyrene insulation is rated at an R-value of 5.0 per inch at 75°F.
Does polyisocyanurate lose R-value?
The trapped gases in the cells of polyiso and XPS foam assist to provide an initial high R-value. During the life of these foams, air from the atmosphere diffuses in and the trapped gases diffuse out. The result is polyiso and XPS lose R-value over their lifetime.

What is polyisocyanurate insulation?
Polyisocyanurate (Polyiso) is a closed-cell, rigid foam board insulation that is bonded to facers on both sides, which are composed of various organic and inorganic materials. Polyiso is used in roof, wall, ceiling and specialty applications within commercial and residential buildings of all types.
What is polyisocyanurate made out of?
Polyisocyanurate foam (polyiso foam) is a cellular, thermoset plastic formed when two basic liquid chemicals, isocyanurate and polyol, are combined in the presence of a catalyst that helps the molecules to rearrange and join, a blowing agent to create closed cells in the structure, flame retardents, and possibly other …
Is polyisocyanurate insulation flammable?
Polyiso insulation, like wood and other organic building materials, is combustible. Therefore, it should not be exposed to an ignition source of sufficient heat and intensity (e.g., flames, fire, sparks, etc.) during transit, storage or product application.
