CPR Isolation Rails

Isolation Rails (CPR System) are engineered to sit between an existing roof curb and curb-mounted rooftop equipment to reduce vibration transfer to the building structure.

Built for performance and field efficiency, CPR Isolation Rails also act as integrated seismic and wind restraints, keeping units securely attached while limiting vibration and noise.

Why Choose Curbs Plus Isolation Rails?

✔ Vibration Control at the Source — Helps minimize energy transmitted from rooftop equipment into the building structure.

✔ Seismic and Wind Restraints Included — Integrated restraints help secure equipment for improved safety and performance under code loading.

✔ Custom Engineered to Fit — Each system is tailored to your specific roof curb and equipment requirements.

✔ Factory-Installed Components — Rails ship nearly assembled — including springs and restraints — reducing installation time and field labor.

✔ Flexible Spring Deflection Options — Choose 1″ or 2″ deflection to match vibration isolation needs.

✔ Easy, Tool-Friendly Installation — Designed for quick field assembly with basic tools.

CPR Isolation Rails

Standard Features
