Ideal for those projects that require high R-value and moisture resistance, but without the demands for a high-compressive strength product. UTILITYFIT™ XPS Insulation is effective in both commercial and residential applications.
UTILIYFIT™ Extruded Polystyrene (XPS) Foam Insulation is a STYROFOAM™ Brand solution manufactured as a versatile, utility-grade product for applications that require a high R-value and outstanding moisture resistance without the need for high compressive strength. UTILITYFIT XPS insulation is designed for use in the United States when a Type X, or lower-compressive strength, product is needed. If the superior properties of a Type IV 25 psi product are not required, UTILITYFIT XPS Insulation is a good choice for your application.
|East to use||
(1) Values are consistent with the criteria of ASTM C578 and the FTC R-value rule (16 CFR Part 460). R means resistance to heat flow. The higher the R-value, the greater the insulating power.
(2) Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since STYROFOAM™ Brand Extruded Polystyrene Foam Insulations are visco-elastic materials, adequate design safetyfactors should be used to prevent long-term creep and fatigue deformation. For static loads, 3:1 is suggested. For dynamic loads, 5:1 is suggested. Contact Dow for design recommendations
