Product Description

All model Building Codes mandate that polyurethane spray foam be separated from the interior of the building by a 15 minute thermal barrier or other approved covering. DC315 has passed certified ULC S101, NFPA 286 and UL 1715 testing, at recognized 3rd party testing facilities, over a variety of open and closed cell spray polyurethane foams. It complies with all the requirements of 2006 IBC Section 803.2.1; 2009 IBC Section 803.1.2 and Section 2603.9; 2012 IBC Section 803.1.2 and Section 2603.10 & & 2015 IBC Section 803.2.1 and IBC Section 2603.9 under “Special Approvals for Thermal Barriers over Foam Plastics”. DC315 also meets the requirement as an Ignition Barrier per AC 377, Appendix X at an incredible spread rate of 400 sq. ft. per gallon.

DC 315 applied over Spray Polyurethane (SPF), is an Alternative Barrier System in "Section 2603.9 Special Approval" as a thermal barrier. To be approved as an Alternative Barrier System, DC 315 is applied over a manufacturer's SPF and tested to the criteria of an NFPA 286, UL 1715, UL 1040, or FM 4880 for duration of 15 minutes by an accredited fire testing facility. Products that pass an ignition barrier tested under AC 377 Appendix X are not appropriate alternative thermal barriers and cannot be used. Depending on your particular application, either ignition or thermal barriers are required by the International Building Code (IBC).
