| Nominal Board Thickness(1), in | R-Value(2) | Board Size, ft | Edge Treatment | Min Compressive Strength(3), psi |
| 2.0 | 10.0 | 2 x 8 / 4 x 8 | Square Edge | 25 |
| 2.5 | 12.5 | 4 x 8 | Square Edge | 25 |
| 3.0 | 15.0 | 2 x 8 / 4 x 8 | Square Edge | 25 |
| 4.0 | 20.0 | 2 x 8 / 4 x 8 | Square Edge | 25 |

(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. RSI values are expressed in m2°C/W. 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 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. |
