ASTIYI E 84 Test for Surface Burning Characteristics of Buildings,;, Materials W 2. NFPA 286 Standard Methods of Fire Tests for Evaluating Contribution of Wall and Ceiling Interior Finish to Room Fire NFPA 286 as modified in AC 377, Appendix X Summary: 1. Based on the test data submitted and the reference documents, SES Foam %2 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 an' d 2009 IRC. 2. Based on the test data submitted and the reference documents, SES Foam %2 lb Spray spray polyurethane foam at a maximum thickness of 11.5 inches may be applied to all geometric construction planes in attics aInd 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 limitations are followed: 1) Entry to the attic orb 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 air -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 proivided 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. Fit C��Op yr Deer Ridge Consulting, Inc. Labeling Requirements: A- and B-components for SES manufacturer's name (SES Foam, L product SES Foam %2 lb Spray); the third -party inspection agency. Discussion: Surface burning unless otherwise allowed, fc having a flame spread index than 450. Intertek Test Reports 1 28, 2011) report the fi E 84: Flame Spread Index Smoke Developed It Therefore, SES Foam %2 lb stipulated in the IBC and IF Page 2 of 4 lb Spray insulation must be identified with the address and telephone number; the name of the insulation spread and smoke developed indices; and the name of the ks: The 2009 IBC and IRC (and earlier editions) require that i plastic must be tested in accordance with ASTM E 84 as not more than 75 and a smoke -developed index of not more 7SAT-003A (June 28, 2011) and 100432887SAT-003B (June at a thickness of four (4) inches in accordance with ASTM 450 insulation meets the surface burning characteristics as 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 (IZ316.3, Exception) provide for testing greater thicknesses in accordance with the Special (Approval and Specific Approval sections, respectively. To this end, SES Foam %2 lb 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 1/2L 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 % lb Spray insulation meets the IBC Special Approval and the IRC Specific Approval sections for application thicknesses up to 11.5 inches when covered with an approved thermal barrier or an approved equivalent thermal barrier. 1 3. Use in attics and crawl spaces: Both the IBC and IRC provide exceptions to the thermal barrier requirement for the us',e 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 • www.deer-ridge-consulting.com Deer Ridge Consulting, Inc. Omitting the prescriptive under the IBC Section 2 Approval. However, neit approval of alternate mats ICC Evaluation Service, in Insulation, provides a prob assemblies to those using f results for the purposes of is accepted within the buildii under IBC Special Approv, Page 3 of 4 lition barriers is permitted under both model building codes .9 Special Approval and the IRC Section R316.6 Specific the IBC or the IRC provides a specific test method for the Is or assemblies to prescriptive ignition barriers. C 377 Acceptance Criteria for Spray -Applied Foam Plastic J in Appendix X based on NFPA 286 to qualify alternate Icriptive ignition barriers. ICC-ES accepts Appendix X test ing Evaluation Reports. Furthermore, this protocol is widely construction community as providing acceptable evidence and IRC Specific Approval sections. Intertek Test Report No. 100432887SAT-002A, June 28, 2011 reports that SES Foam % lb Spray passes the AC 377, A pendix 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). Therefore, SES Foam %21b 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 %21b Spray insulation beets the requirements of IRC Section R316.5.1 I for 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 as specified and as limited in the Respectfully submitted, Deer Ridge Consulting, Inc. Roger V. Morrison, PE, RRC President Reference Documents: n meets the requirements and intent of the IBC and IRC section above. 1. 2009 International Building Code: Sections 803.1.2.1; 2603. 2. 2009 International Residential (Code: Sections R302.9.4; R316. 505 Deer Ridge Lane • Ararat, VA 24053 • 276-755-9162 • www.deer-ridge-consulting.com Deer Ridge Consulting, Inc. 3. 4. 5. 6. 7.
