Safe homes use fire-safe claddings, which include vinyl siding. Why does vinyl siding provide good fire performance? It is composed mainly of polyvinyl chloride, more commonly known as vinyl or PVC. Due to its chlorine base, vinyl siding does not ignite quickly and is inherently flame-retardant.

What’s more, the facts show that exterior cladding is involved in only a fraction of all residential fires. According to the National Fire Protection Agency, only 4 in 100 house fires start on the outside of a structure and fewer than 2 of 100 house fires originate with the exterior wall surface.

Additionally, vinyl meets the stringent National Fire Protection Association (NFPA) requirements. The NFPA Electrical Code recognizes the strong fire-safe characteristics of vinyl through its approved use as a residential wiring insulator. Millions of homes have been wired using safe vinyl-sheathed electrical systems for decades.¹
