Product Data Sheet FOAMULAR INSUL-DRAIN Extruded Polystyrene (XPS) Insulation Board It is suggested that a bead of waterproof sealant be applied in the edge groove area in order to retard water penetration to the foundation wall. Additional INSUL- DRAIN boards should be installed in a similar fashion. The remaining fabric overhang on the tongue side should be overlapped onto the adjacent board and secured with a bead of compatible adhesive. 5. INSUL-DRAIN boards can be trimmed to fit project dimensions or protrusions by scoring with a utility knife or cut with a handsaw. It is recommended that all length cutting take place on the bottom of the board. 6. At wall corners where two INSUL-DRAIN boards intersect, one board should be trimmed flush with the wall and the second board trimmed to overhang the wall, by the thickness of the product, to produce a continuous thermal envelope. A bead of waterproof sealant should be applied vertically where the boards join each other. The fabric overhang should then be attached to the surface of the adjacent board with compatible adhesive. 7. Additional tiers of INSUL- DRAIN boards should be installed the same as the first tier. Be certain to secure all fabric overhangs to adjacent boards with compatible adhesive. 8. Owens Corning recommends that INSUL-DRAIN boards be at least partially backfilled the same day as installation to stabilize and secure the boards in place. The balance of the backfill should be added as soon as practical to fully secure the boards and protect them from jobsite damage and UV exposure. Care should be exercised during the backfill operation as to not allow soil penetration between INSUL-DRAIN board and the foundation wall. As an alternative, in conjunction with partial backfilling, compatible construction adhesives can be used to temporarily secure INSUL-DRAIN boards. Beads or spots of compatible adhesive can be dabbed to the backside of INSUL-DRAIN board and then pressed firmly in place against the wall. 9. INSUL-DRAIN board should not be installed unprotected above grade. In order to achieve a continuous thermal envelope, standard FOAMULAR insulation panels should be installed against the foundation wall from the top Typical Physical Properties 1 FOAMULAR INSUL-DRAIN Extruded Polystyrene Insulation Board Property Test Method 2 Value Thermal Resistance 3 , R-Value (180 day) minimum, Fft 2 hr/Btu (RSI, Cm 2 /W) @ 75F (24C) mean temperature ASTM C 518 1" Thickness 4.4 (0.77) 1" Thickness 6.9 (1.21) 2" Thickness 10.6 (1.87) @ 40F (4.4C) mean temperature 1" Thickness 4.7 (0.83) 1" Thickness 7.4 (1.31) 2" Thickness 11.4 (2.01) Compressive Strength 4 , minimum psi (kPa) ASTM D 1621 25 (172) Drainage Capacity 5 , ASTM @ 500 psf, gal/min/ft ASTM D 4716 12.0 Water Absorption 6 , maximum % by volume ASTM C 272 0.10 Water Vapor Permeance 7 , maximum perm (ng/Pasm 2 ) ASTM E 96 1.5 (86) Dimensional Stability, maximum % linear change ASTM D 2126 2.0 Flame Spread 8, 9 ASTM E 84 5 Smoke Developed 8, 9, 10 ASTM E 84 45-175 Oxygen Index 8 , minimum % by volume ASTM D 2863 24 Service Temperature, maximum F (C) - 165 (74) Linear Coefficient of Thermal Expansion, in/in/F (m/m/C) ASTM E 228 3.5 x 10 -5 (6.3 x 10 -5 ) 1. Properties shown are representative values for 1" thick core material, unless otherwise specified. 2. Modified as required to meet ASTM C 578 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 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. 4. Values at yield or 10% deflection, whichever occurs first. 5. Per lineal foot of width. Tested at a uniform load of 500 psf for 300-hour duration according to ASTM D4716. 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 E 84 is thickness-dependent, therefore a range of values is given.
