PRODUCT DATA SHEET FOAMULAR 250 Extruded Polystyrene (XPS) Rigid Foam Insulation Description Owens Corning FOAMULAR 250 Extruded Polystyrene (XPS) Insulation is a closed cell, moisture-resistant rigid foam board well suited to meet the needs for a wide variety of building applications. FOAMULAR 250 XPS insulation is great for many residential and commercial construction applications such as wall furring, perimeter/foundation, cavity wall, pre-cast concrete, under slab, crawl spaces, sheathing and other applications. Features Excellent long-term stable insulating performance at R-5 1 per inch Exceptional moisture resistance, long-term durability 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. Applications Slows the transmission of water vapor and moisture in masonry walls Provides continuous insulation over wood or steel stud framing, in insulated concrete sandwich panel walls, in masonry unit cavity walls, or when used with non-penetrating, surface mounted furring systems over masonry or concrete walls Insulates and retains its properties in below grade perimeter and foundation applications, or directly beneath the concrete slab to complement the insulating sheathing envelope around the building framing Physical Properties 2 Property Test Method 3 Value Thermal Resistance 4 , R-value (180 day) minimum, hrft 2 F/Btu (RSI, Cm 2 /W) @ 75F (24C) mean temperature ASTM C518 " Thickness 4.0 (0.70) 1" Thickness 5.0 (0.88) 1" Thickness 7.5 (1.32 2" Thickness 10 (1.76) 2" Thickness 12.5 (2.20) 3" Thickness 15 (2.64) 4" Thickness 20 (3.52) @ 40F (4.4C) mean temperature " Thickness 4.3 (0.76) 1" Thickness 5.4 (0.95) 1" Thickness 8.1 (1.43) 2" Thickness 10.8 (1.90) 2" Thickness 13.5 (2.38) 3" Thickness 16.2 (2.85) 4" Thickness 21.6 (3.80) Long Term Thermal Resistance, LTTR-value 4 , minimum hrft 2 F/Btu (RSI, Cm 2 /W) @ 75F (24C) mean temperature CAN/ULC S770-03 " Thickness N/A 1" Thickness 5.0 (0.88) 1" Thickness 7.8 (1.37) 2" Thickness 10.6 (1.87) 2" Thickness 13.4 (2.36) 3" Thickness 16.2 (2.85) 4" Thickness 22.0 (3.87) Compressive Strength 5 , minimum psi (kPa) ASTM D1621 25 (172) Flexural Strength 6 , minimum psi (kPa) ASTM C203 50 (345) Water Absorption 7 , maximum % by volume ASTM C272 0.3 Water Vapor Permeance 8 , maximum perm (ng/Pasm 2 ) ASTM E96 1.5 (86) Dimensional Stability, maximum % linear change ASTM D2126 2.0 Flame Spread 9, 10 ASTM E84 10 Smoke Developed 9, 10, 11 ASTM E84 175 Oxygen Index 12 , minimum % by volume ASTM D2863 24 ServiceTemperature,maximum F(C) 165 (74) LinearCoefficientofThermalExpansion,in/in/F(m/mC) ASTM E228 3.5 x 10 -5 (6.3 x 10 -5 ) 2. Properties shown are representative values for 1" thick material, unless otherwise specified. 3. Modified as required to meet ASTM C578. 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 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. 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.
