Product Details

Acoustex is a high-quality open-cell acoustic insulation material from Aeroflex, specifically designed for HVAC ducts. Made from a specialized porous open-cell rubber structure, it effectively absorbs sound waves, refracts frequencies, and reduces noise transmission from motors, fans, or airflow. With a Noise Reduction Coefficient (NRC) of up to 0.65, it is health-safe and eliminates issues with dust or fibers contaminating the air conditioning system.

 

Size: 1.2 x 7.2 m, 25 mm thick

Acoustex (Open-cell foam) for duct systems in central HVAC and ventilation systems. Noise from machinery vibration and airflow within steel ducts is a primary cause of indoor disturbance. Acoustex was developed as the premier solution for these noise issues, utilizing open-cell technology that outperforms traditional insulation.

Key features of Acoustex (Open-cell foam)

  • High Noise Absorption: With an NRC (Noise Reduction Coefficient) of up to 0.65, it significantly captures and attenuates sound frequency energy.
  • Special Open-Cell Foam Structure: The open-pore structure forces incoming sound waves to refract and rapidly convert into heat energy.
  • Safe, Dust & Fiber-Free: Unlike traditional fiberglass insulation, Acoustex does not shed particles or dust. This prevents airflow contamination, keeping Indoor Air Quality (IAQ) pure and safe for the respiratory system.
  • Non-Eroding at High Air Velocity: The insulation material is robust and resistant to high-pressure airflow within ducts. It will not deteriorate, crumble, or become brittle throughout its service life.
  • Flexible & Easy Installation: Supplied in rolls, this lightweight material can be easily cut to fit duct curves or tight spaces, saving time and labor costs.

 

Ideal Applications

  • HVAC Duct Lining: Internal acoustic lining for supply, return, and exhaust air ducts in offices, hotels, malls, and hospitals.
  • AHU & FCU Insulation: Internal acoustic lining for Air Handling Units and Fan Coil Units to reduce motor noise.
  • Acoustic Enclosures: Used for lining machine rooms, soundproof rooms, or music studios requiring echo control.
