Why Global Clients Choose ISVPL
Ultra‑Low‑Frequency Technology
Steel mass‑spring isolation systems tuned down to about 1.4 Hz vertical and 1.0 Hz horizontal, targeting frequencies that drive severe earthquake and vibration demands.
Data‑Driven Engineering
Every solution is backed by on‑site measurements, simulation and standards‑based design, providing traceable, defensible performance.
Proven Vibration Reduction
Systems designed to achieve around 42 VdB attenuation across the 0–250 Hz band, significantly lowering transmitted vibration to people, equipment and structures.[web:142][web:148]
