  1. Unfaced only
  2. Per ASTM D5385 / C1306
  3. Properties shown are representative values for 1-inch-thick material unless otherwise specified. Cellular glass may exhibit different physical properties based upon thickness. Certain physical properties are listed by minimum and maximum values per ASTM C1902. For details on specific test methods, please contact Owens Corning at 1-800-GET-PINK.
  4. Maximum change in any dimension.
  5. These laboratory tests are not intended to describe the hazards under actual fire conditions. Verify compliance with all required applicable fire assemblies.
  6. 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 market R-value. Follow the manufacturer’s instructions carefully. The U.S. FTC requires the R-value of home insulation to be measured at 75°F mean temperature. R-value claims should always be compared at the same mean temperature. 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.
