Division 7 Ebook Page 265 DURAPINK® XPS Insulation Product Data Sheet

Product Data Sheet FOAMULAR DURAPINK Extruded Polystyrene (XPS) Rigid Foam Insulation When installing DURAPINK roofing recovery board beneath a dark-colored, mechanically attached membrane, Owens Corning recommends the installation of eight fasteners and stress plates per 4'x8' panel. The diagram shows the recommended fastener placement. For fully adhered and ballasted systems, contact the specific membrane manufacturer or Owens Corning for fastening recommendations. When installing DURAPINK roofing recovery board beneath a white, mechanically attached roof system, a minimum of one fastener per eight square feet is required to secure the board, placed within 6" of each corner of 4'x8' panel. This limited amount of fasteners is acceptable but may allow some board movement. Install two to four additional fasteners in the center field as shown in the fastening diagram for enhanced flatness. The membrane should be laid out perpendicular to the long dimension of DURAPINK roofing recovery board panels. Some membranes, such as PVC containing plasticizers, will require a separator between DURAPINK roofing recovery board and the membrane. For roofing and other horizontal applications, product should be installed with the printed surface facing downward. DURAPINK roofing recovery board can be installed over coal tar pitch (CTP) provided the existing coal tar is at least ten years old and has not been re- saturated in the last four years. If those age criteria are not met, a 6 mil polyethylene sheet will serve as an adequate separator between CTP and XPS.

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. The " is actually a nominal half-inch of 9/16th needed to achieve 3.0 R-value. 5. Values at yield or 10% deflection, whichever occurs first. 6. Value at yield or 5%, whichever occurs first. 7. Data ranges from 0.00 to value shown due to the level of precision of the test method. 8. Water vapor permeance decreases as thickness increases. 9. These laboratory tests are not intended to describe the hazards presented by this material under actual fire conditions. 10. Data from Underwriters Laboratories Inc. classified. See Classification Certificate U-197. 11. ASTM E84 is thickness-dependent, therefore a range of values is given.
