Protect I-Joists

DC5040 is a water based thin film intumescent coating used to provide fire resistance to engineered wood framing members such as I-Joists.

Evaluation Report

ER-0568 Evaluation Report

DC5040 has been evaluated for use as a fire-protective coating for wood-based products. The coating has been evaluated as part of a fire-resistance-rated assembly and for interior finish. The fire resistance, surface burning characteristics, durability, and effects on mechanical properties of the I-joist comply with the intent of the provisions of the following codes and regulations:

  • 2018, 2015 and 2012 International Residential Code® (IRC)

DC5040 is a water based thin film intumescent coating providing fire resistance to I-Joist and engineered wood framing members. Applied to the I-Joist only, once the I-Joist 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.

SAVE MONEY USING DC5040

National averages confirm that the cost per sq. ft. to install a coating vs. ½” Gypsum is about the same.  Given the fact that, when using DC5040, all you must coat is the I-Joist you reduce the square footage required to be protected by 20-30% over the installation of Gypsum and hence reduce the overall cost by 20-30%!!
