Why CPVC for Fire Protection

Self-extinguishing. Corrosion-free. Faster to install.

CPVC compound is the internationally accepted alternative to steel in fire-sprinkler installations — lighter, corrosion-free and faster to install with solvent cement rather than threaded steel fittings.

  • CPVC compound is inherently self-extinguishing — does not sustain combustion once ignition source is removed
  • Rated for fire-protection sprinkler systems in residential and commercial buildings
  • Higher heat deflection temperature than standard uPVC — maintains integrity in elevated ambient temperatures
  • Solvent-cement jointing — fast, leak-free installation by certified fire-plumbing contractors
  • Corrosion-free — no rust, scale or pitting over the system life
  • Lightweight vs. metal sprinkler pipe — reduces installation time and cost on high-rise projects
  • Colour-coded (typically red or orange) for easy identification as fire-service pipework
