the foam surface under the print. Additional protection over FOAMULAR XPS Insulation such as added cover boards, reflective membrane surfaces, or pavers may be required in areas adjacent to reflective walls, parapets, rooftop equipment areas or other vertical surfaces that may reflect and intensify the sun's energy. 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. See Owens Corning publication number 10015704, "Heat Build Up Due to Solar Exposure" for more information. FOAMULAR XPS Insulation can be stored outdoors 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 installed within 60 days to minimize degradation. Once installed and 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.

Properties shown are representative values for 1" thick material, unless otherwise specified. 2. Modified as required to meet ASTM C578. 3. R means the resistance to heat flow; the higher the value, the greater the insulation power. This insulation must be installed properly to get the marked R-value. Follow the manufacturer's instructions carefully. If a manufacturer's fact sheet is not provided with the material shipment, request this and review it carefully. R-values vary depending on many factors including the mean temperature at which the test is conducted, and the age of the sample at the time of testing. Because rigid foam plastic insulation products are not all aged in accordance with the same standards, it is useful to publish comparison R-value data. The R-value for FOAMULAR XPS Insulation is provided from testing at two mean temperatures, 40F and 75F, and from two aging (conditioning) techniques, 180 day real- time aged (as mandated by ASTM C578) and a method of accelerated aging sometimes called "Long Term Thermal Resistance" (LTTR) per CAN/ULC S770-03. The R-value at 180 day real-time age and 75F mean temperature is commonly used to compare products and is the value printed on the product. 4. Values at yield or 10% deflection, whichever occurs first. 5. Value at yield or 5%, whichever occurs first. 6. Data ranges from 0.00 to value shown due to the level of precision of the test method. 7. Water vapor permeance decreases as thickness increases. 8. These laboratory tests are not intended to describe the hazards presented by this material under actual fire conditions. 9. Data from Underwriters Laboratories Inc. classified. See Classification Certificate U-197. 10. ASTM E84 is thickness-dependent, therefore a range of values is given.
