DC5040 is a water based thin film intumescent coating used to provide fire resistance to engineered wood framing members such as I-Joists. Applied to the I-Joist only, once the components are installed, DC5040 provides equivalence to the 2- by-10-dimension lumber prescribed in Section R302.13, Exception 4 of the 2015 IRC® and Section R501.3, Exception 4 of the 2012 IRC®. DC5040 has been fire tested in accordance with a full-scale ASTM E-119 and meets IAPMO UES Acceptance Criteria EC017 for Field-Applied Fire Protective Coatings. Other coating testing requires BOTH the I-Joists and the sub floor to be coated. DC5040’s superior performance is tested, as a single coat, applied to the I-Joist only. Subfloors can add up to 50% more surface area to be coated, DC5040 maximizes yield, reduces labor and provides a cost effective solution to meeting IRC Code requirements. Read More
