ASTM E 84 Test for Surface Burning Characteristics of Building Materials 2. NFPA 286 Standard Methods of Fire Tests for Evaluating Contribution of Wall and Ceiling Interior Finish to Room Fire Growth 3. NI PA 286 as modified in AC 377, Appendix X I Summary: 1. Based on the test data submitted and the reference documents, SES Foam % lb Spray spray polyurethane foam at a maximum thickness of 11.5 inches in walls and/or ceilings, covered with an approved or equivalent thermal barrier meets the requirements for use under 2006 IBC, 2006 IRC, 2009 IBC'land 2009 IRC. 2. Based on the test data submitted and the reference documents, SES Foam''/z lb Spray spray polyurethane foam at a maximum thickness of 11.5 inches may be applied to all geometric construction planes in attics and crawl spaces without the prescribed protection from ignition as required in 2009 IBC Section 2603.4.1.6 or 2009 IRC Sections R316.5.3 and R316.5.4 provided the following limi tations are followed: 1) Entry to the attic or crawl spaces is only to service utilities and no storage is permitted. 2) There are no interconnected attic or crawl space areas. 3) Air in the attic or crawl space is not circulated to other parts of the building. 4) Attic ventilation is provided when required by IBC Section 1203.2 or IRC Section R806, except when 6ir-impermeable insulation is permitted in unvented attics in accordance with Section R806.4 of IRC, Under -floor (crawl space) ventilation is provided when required by IBC Section 1203.3 or IRC Section R408.1, as applicable. 5) Combustion air is provided in accordance with Sections 701 and 703 2006 IMC) and Section 701 (2009 IMC). 3. Based on the test data submitted and the reference documents, SES Foam %2 lb Spray spray polyurethane at a maximum thickness of 3.25 inches would not need to be covered with a thermal barrier when applied'to sill plates and headers in accordance with 2009 IRC Section R316.5.11. FILE Deer Ridge Consulting, Inc. Labeling Requirements: Page 2 of 4 A- and B-components for SES Foam %2 lb Spray insulation must be identified with the manufacturer's name (SES Foam, LLC), address and telephone number; the name of the insulation product SES Foam %2 lb Spray);,the flame spread and smoke developed indices; and the name of the third -party inspection agency. Discussion: 1. Surface burning characteristics: The 2009 IBC and IRC (and earlier editions) require that unless otherwise allowed, foam plastic must be tested in accordance with ASTM E 84 as having a flame spread index of not more than 75 and a smoke -developed index of not more than 450. Intertek Test Reports 1004132887SAT-003A (June 28, 2011) and 100432887SAT-003B (June 28, 2011) report the following at a thickness of four (4) inches in accordance with ASTM E 84: Flame Spread Index 5 Smoke Developed Index 450 i 1 Therefore, SES Foam %2 lb Spray insulation meets the surface burning characteristics as stipulated in the IBC and IRC. 2. Maximum thickness: The maximum thickness that can be tested in accordance with ASTM E 84 is four (4) inches. For thicknesses greater than four inches, the IBC (Section 2603.3, Exception 4) and the IRC (R316.3, Exception) provide for testing greater thicknesses in accordance with the Special Approval and Specific Approval sections, respectively. To this end, SES Foam %2 'alb Spray has been tested in accordance with NFPA 286 and reported in Intertek Test Report No. 100432887SAT-001, June 28, 2011. The foam plastic was tested covered with 1/2-inch gypsum wall board (an approved thermal barrier) at a thickness of 11.5 inches in the walls and ceiling. The test assembly met the pass/fail criteria of IBC Section 803 (IRC has a similar pass/fail criteria but the IBC criteria is more stringent). Therefore, SES Foam''/2 lb Spray insulation meets the IBC Special Approval and the IRC Specific Approval sections fo'r application thicknesses up to 11.5 inches when covered with an approved thermal barrier or an approved equivalent thermal barrier. 3. Use in attics and crawl spaces: Both the IBC and IRC provide exceptions to the thermal barrier requirement for the use of foam plastic insulation in certain attics and crawl spaces. Specifically, both model building codes provide for protecting the foam plastic from ignition through the use of coverings described as prescriptive ignition barriers (2009 IBC Section 2603.4.1.6 or 2009 IRC Sections R316.5.3 and R316.5.4). 505 Deer Ridge Lane • Ararat, VA 24053 • 276-755-9162 Deer Ridge Consulting, Inc. Page 3 of 4 Omitting the prescriptive ignition barriers is permitted under both model building codes under the IBC Section 2603.9 Special Approval and the IRC Section R316.6 Specific Approval. However, neither the IBC or the IRC provides a specific test method for the approval of alternate materials or assemblies to prescriptive ignition barriers. ICC Evaluation Service, in AC 377 Acceptance Criteria for Spray -Applied Foam Plastic Insulation, provides a protocol in Appendix X based on NFPA 286 to qualify alternate assemblies to those using prescriptive ignition barriers. ICC-ES accepts Appendix X test results for the purposes of issuing Evaluation Reports. Furthermore, this protocol is widely accepted within the building construction community as providing acceptable evidence under IBC Special Approval and IRC Specific Approval sections. i Intdrtek Test Report No!1 100432887SAT-002A, June 28, 2011 reports that SES Foam %2 lb Spray passes the AC 377, Appendix X protocol at a maximum thickness of 11.5 inches in the walls and ceiling. No prescriptive ignition barriers covered the foam plastic in this test; neither were there any coatings or other coverings applied (i.e., the foam plastic was left exposed for this test). I Therefore, SES Foam V21b Spray meets the Special Approval and Specific Approval sections of the IBC and IRC respectively for use in attics and crawl spaces. The limitations as stipulated in AC 377, Appendix X apply. 4. Sill plates and headers: Based on the surface burning characteristics referenced above, SES Foam %2 lb Spray insulation meets the requirements of IRC Section R316.5.1 Ifor use on sill plates and headers without being covered with a thermal barrier at a maximum thickness of 3.25 inches. Conclusions: SES Foam %21b Spray foam plastic insulation meets the requirements and intent of the IBC and IRC as specified and as limited in the Summary section above.
