Product Data Sheet FOAMULAR 400/600/1000 Extruded Polystyrene (XPS) Rigid Foam Insulation 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 Extruded Polystyrene Insulation has a maximum service temperature of 165F. Taking simple precautions during construction can minimize the potential for heat related damage. Install only as much FOAMULAR XPS Insulation as can be covered in the same day. For 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, raising the temperature of the foam under the print to an unacceptable level. Provide a final finish covering or temporary white opaque covering to avoid possible damage when dark (non-white) surfaces are used over FOAMULAR XPS Insulation. 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, FOAMULAR XPS Insulation deformation damage may occur rapidly. See Owens Corning publication number 10015704, "Heat Build Up Due to Solar Exposure" for more information. Standards, Codes Compliance Meets ASTM C578 Type VI (FOAMULAR 400 XPS Insulation), Type VII (FOAMULAR 600 XPS Insulation), or Type V (FOAMULAR 1000 XPS 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.
