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

Installing ACOUSTEX acoustic insulation in AC ducts<\/p><\/div>\n

 <\/p>\n

Key features of Acoustex (Open-cell foam)<\/h3>\n
    \n
  • High Noise Absorption:<\/b> With an NRC (Noise Reduction Coefficient) of up to 0.65, it significantly captures and attenuates sound frequency energy.<\/span><\/li>\n
  • Special Open-Cell Foam Structure:<\/b> The open-pore structure forces incoming sound waves to refract and rapidly convert into heat energy.<\/span><\/li>\n
  • Safe, Dust & Fiber-Free:<\/b> 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.<\/span><\/li>\n
  • Non-Eroding at High Air Velocity:<\/b> 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.<\/span><\/li>\n
  • Flexible & Easy Installation:<\/b> Supplied in rolls, this lightweight material can be easily cut to fit duct curves or tight spaces, saving time and labor costs.<\/span><\/li>\n<\/ul>\n

     <\/p>\n

    Ideal Applications<\/h3>\n
      \n
    • HVAC Duct Lining:<\/b> Internal acoustic lining for supply, return, and exhaust air ducts in offices, hotels, malls, and hospitals.<\/span><\/li>\n
    • AHU & FCU Insulation:<\/b> Internal acoustic lining for Air Handling Units and Fan Coil Units to reduce motor noise.<\/span><\/li>\n
    • Acoustic Enclosures:<\/b> Used for lining machine rooms, soundproof rooms, or music studios requiring echo control.<\/span><\/li>\n<\/ul>\n
