**Not all product sizes are available in all regions.
† 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.
†† Vertical compressive strength is measured at 10% deformation (5% for STYROFOAM HIGHLOAD 40, 60 and 100 insulation products) or at yield, whichever occurs first. Since STYROFOAM extruded polystyrene insulation products are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep and fatigue deformations.
