Go to this website and check out the various supplier's ES reports. http://www.icc-es.org/reports/index.cfm?list=list I found one that is listed at 4.1 at one inch but at 3 inches totals R 11. Open cell foam tends to have less R value per inch at thicker applcations OK, I found a total of 4 systems that report 4.0 or higher R values at one inch and 2 that have 4.0 R value per inch at 4 inches or more. These are the reports. NCFI ESR 1154. R value 4.1 at one inch but 3.7 per inch at 3.5 inches Demilec ESR 2600 R value 4.6 at one inch and 17.8 at 4 inches (4.45 per inch) Gaco Western ESR 2478 4.2 at one inch and at 3.9 per inch at 4 inches Urethane Soy Systems 4.0 at one inch at 4.27 per inch at 4 inches. Let me know if I missed a few. |
