IC-SONO
Sound Proofing Membrane

IC‑SONO is a two-component urethane hybrid membrane designed to reduce sound and noise in institutional, residential, and commercial buildings. It offers long-term durability, extended open time, and strong acoustical properties.
This membrane provides excellent adhesion to a variety of substrates and can be applied over damp concrete. It forms a dense, bacteria- and moisture-resistant surface that is easy to clean and resistant to thermal shock.
Advantages
  • 100% solids, low odor
  • Excellent sound dampening & anti-vibration properties
  • Moisture-resistant membrane
  • Easy to clean, seamless surface
  • Flexible with high elongation
  • Long open time for installation
  • Adheres well to many substrates including damp concrete
Primary Applications
  • Apartments / Condos
  • Hotels
  • Commercial buildings
  • Freezers / Refrigerated areas
  • Treatment plants
  • Mechanical & electrical rooms
  • Laboratories
  • Food processing areas
