Product Data Sheet FOAMULAR Tapered Roofing Products Extruded Polystyrene (XPS) Rigid Foam Insulation Lightweight, durable rigid foam panels are easy to handle and install Easy to saw, cut or score Technical Information The roof designer must specify the number and location of roof drains as well as the minimum roof slope required for projects using Owens Corning THERMAPINK tapered roof insulation. Please note that Chapter 15 of the IBC requires a minimum slope of " per foot for many new construction roofing systems, while requiring only positive slope for reroof systems. Owens Corning THERMAPINK tapered roof insulation is available in " and 1 /8" slopes as well as other custom slopes on request. THERMAPINK tapered roof insulation has been tested over steel roof decks without a thermal barrier in accordance with UL Standard 1256 and is listed for use direct to deck in accordance with UL Roof Deck Construction #457. If the tapered maximum thickness exceeds that permitted by #457, a thermal barrier may be required. Check local codes for additional requirements. This product is combustible. For additional information, consult MSDS or contact Owens Corning World Headquarters at 1-800-GET-PINK . 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. It is recommended that all THERMAPINK tapered roof insulation printed surfaces be turned down to minimize potential sun exposure and localized heat accumulation on the print. FOAMULAR Extruded Polystyrene Insulation is a thermoplastic material with a maximum service temperature of 165F. In horizontal applications, FOAMULAR XPS Insulation may experience greater solar exposure than in vertical applications and it may be damaged by heat buildup. Simple precautions during construction can minimize the potential for Typical Physical Properties 1 FOAMULAR Tapered Roofing Products Exturded Polystyrene (XPS) Rigid Foam Insulation FOAMULAR Tapered Products Property Test Method 2 Tapered TP25 Tapered F400 Tapered F600 Thermal Resistance 3 , R-Value (180 day) minimum, hrft 2 F/Btu (RSI, Cm 2 /W) @ 75F (24C) mean temperature ASTM C518 5.0 (0.88) @ 40F (4.4C) mean temperature 5.4 (0.95) Compressive Strength 4 , minimum psi (kPa) ASTM D1621 25 (172) 40 (276) 60 (414) Flexural Strength 5 , minimum psi (kPa) ASTM C203 75 (517) 115 (793) 140 (965) Water Absorption 6 , maximum % by volume ASTM C272 0.10 0.05 Water Vapor Permeance 7 , maximum perm (ng/Pasm 2 ) ASTM E96 1.5 (86) 1.1 (63) 1.1 (63) Dimensional Stability, maximum % linear change ASTM D2126 2.0 Flame Spread 8, 9 ASTM E84 5 Smoke Developed 8, 9, 10 ASTM E84 45-175 Oxygen Index 8 , minimum % by volume ASTM D2863 24 Service Temperature, maximum F (C) - 165 (74) Linear Coefficient of Thermal Expansion, in/in/F (m/m/C) ASTM E228 3.5 x 10 -5 (6.3 x 10 -5 ) 1. 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. This laboratory test is 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. Smoke Developed is thickness-dependent, therefore a range of values is given.
