STYROFOAMâ„¢ Brand CAVITYMATEâ„¢ Ultra Insulation uses patented carbon black materials in the foam for greater thermal performance over other extruded polystyrene foam insulations. This enhanced formulation helps the extruded polystyrene foam to absorb infrared radiation, slowing transmission through the foam and lowering heat flow. Special 16" (400 mm) width with square edges on all four sides makes it easy to fit between brick ties in cavity wall applications. It also offers high moisture resistance and durability, and is available in butt edge and shiplap edge treatments.
Building Code Compliance
Complies with ASTM C578 Type IV. Patented carbon black technology provides high R-value per inch of thickness. Meets IBC/IRC requirements for foam plastic insulation. Meets CAN/ULC S701 Type 3. See ESR-2142, BOCA-ES RR 21-02. UL Classified, see Classification Certificate D369.

| Nominal Board Thickness(1), in | R-Value(2) | Board Size, ft | Edge Treatment | Min Compressive Strength(3), psi |

(1) Not all product sizes are available in all regions. (2) R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2• h•°F/Btu. R-value determined by ASTM C518. (3) Vertical compressive strength is measured at 10% deformation (5% for STYROFOAM™ Brand PLAZAMATE™ Insulation and for STYROFOAM™ Brand HIGHLOAD 40, 60, and 100 Insulation products) or at yield, whichever occurs first. Since STYROFOAM™ Brand Extruded Polystyrene Foam and Dow polyisocyanurate insulation products are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep. For static loads, 3:1 is suggested. For dynamic loads, 5:1 is suggested. |
