PRODUCT DATA SHEET FOAMULAR CW15/CW25 Extruded Polystyrene (XPS) Rigid Foam Insulation Description Owens Corning FOAMULAR CW15 and CW25 Extruded Polystyrene (XPS) Insulation are closed cell, moisture- resistant rigid foam boards designed for cavity wall applications. Pre-cut 16" wide boards yield fast, labor-saving installation. Features Excellent long-term stable insulating performance of R-5 1 per inch Exceptional moisture resistance, long-term durability Reusable Lightweight, durable rigid foam panels are easy to handle and install Easy to saw, cut or score 1. R means the resistance to heat flow; the higher the R-value, the greater the insulating power. Technical Information FOAMULAR XPS insulation is a non-structural material and must be installed on framing which is independently braced and structurally adequate to meet required construction and service loading conditions. 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. This product is combustible. A protective barrier or thermal barrier is required to separate this product from interior living or conditioned spaces as specified in the appropriate building code. All construction should be evaluated for the necessity to provide vapor retarders. See current ASHRAE Handbook of Fundamentals.

Properties shown are representative values for 1" thick material, unless otherwise specified. 3. Modified as required to meet ASTM C 578. 4. 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 C 578) 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. 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 E 84 is thickness-dependent, therefore a range of values is given.
