Product Data Sheet FOAMULAR DURAPINK Extruded Polystyrene (XPS) Rigid Foam Insulation See DURAPINK roofing recovery board guide specifications for complete installation details. All construction should be evaluated for the necessity to provide vapor retarders. See current ASHRAE Handbook of Fundamentals. FOAMULAR XPS Insulation can be exposed to the exterior during normal construction cycles. During that time some fading of color may begin due to UV exposure, and, if exposed for extended periods of time, some degradation or "dusting" of the polystyrene surface may begin. It is best if the product is covered within 60 days to minimize degradation. Once covered, the deterioration stops, and damage is limited to the thin top surface layers of cells. Cells below are generally unharmed and still useful insulation. FOAMULAR XPS Insulation is a thermoplastic material with a maximum service temperature of 165F. For DURAPINK XPS that is of proper thickness and installed per manufacturers recommendations, installation under a dark membrane is an acceptable application. However, until properly placed and secured, if stored under dark (nonwhite) or clear (non-opaque) materials, in horizontal applications (such as on roof decks), it may experience greater solar exposure and it may be damaged by heat buildup. Simple precautions during construction can minimize the potential for heat related damage. For all horizontal applications always turn the print side down so the black print does not show to the sun which may, at times, act as a solar collector and raise the temperature of the foam surface under the print. Do not cover FOAMULAR XPS Insulation either stored (factory wrapped or unwrapped), or partially installed, with dark colored (non-white), or clear (non-opaque) coverings and leave it exposed to the sun. Examples of such coverings include but are not limited to filter fabrics, membranes, temporary tarps, clear polyethylene, etc. If improperly covered, and exposed to the right combination of sun, time and temperature, deformation damage may occur rapidly. When covering is necessary, use only white opaque material, or, cover with the final approved finish material as soon as possible. A white opaque cover reflects energy from the sun rather than absorbing it or passing it which reduces the potential for excessive heat exposure. Clear (non-opaque) coverings allow light energy from the sun to pass through rather than reflect it which may produce a partial greenhouse effect, trapping hot air and raising the temperature below the cover.
