Using spray foam in exterior wall cavity applications? Compliance with NFPA 285 is required by code. You probably already know that DC315 provides thermal and ignition barrier compliance! However, there are other ways to use thermal barriers to provide property protection. Did you know that you can use DC315 with a protective topcoat where foam is applied to the exterior of a building envelope? Using DC315 allows designers to use a broad range of architectural cladding, such as aluminum panels.
Fire-resistant contracting products are manufactured to inhibit the spread of flames and reduce the combustibility of building surfaces. Our DC315 Intumescent Coating is an internationally popular fire-resistant product with a protective topcoat for use on exterior walls. Unlike conventional exterior paints, which may contribute to the rapid spread of fire, fire-resistant paint for wood and other exterior building materials creates a protective barrier that helps delay ignition. They also help to slow down the progression of flames in case of fire.
Why Use Spray Foam in Exterior Wall Cavities?
The primary benefit of using spray foam in exterior wall cavities is energy efficiency. SPF provides a robust all-in-one-insulation, air barrier and vapor control layer. Much like putting on a jacket in winter, the full building envelop is protected, not just the space between studs. Using DC315 intumescent coating with a weather protective topcoat allows compliance to NFPA 285 and meets or exceeds regulatory standards. This ensures compliance with local building codes and contributes to a safer community.
Most international fire codes reference the NFPA, which makes our NFPA-compliant intumescent coatings the easy choice for builders, contractors and property renovators all over the world. Keep your properties up to local codes, meet international fire safety standards, and feel confident that every property your team constructs will keep its inhabitants as safe as possible.
