(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 HIGHLOAD 40, 60 and 100 Insulation products) or at yield, whichever occurs first. Since STYROFOAM™ Brand Extruded Polystyrene Foam 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. |
