All About Duct Liner Adhesive: Enhancing Efficiency and Performance in HVAC Systems


Duct liner adhesive plays a crucial role in the HVAC (Heating, Ventilation, and Air Conditioning) industry. Developed by Aeroflex USA, a leading manufacturer of EPDM insulation solutions, duct liner adhesive offers a high-performance solution for enhancing energy efficiency and reducing noise levels in HVAC systems.

What is Duct Liner Adhesive?

Duct liner adhesive is a specially formulated adhesive designed for securing and attaching duct liner insulation materials to the internal surfaces of air ducts. It is a key component in creating a well-insulated and acoustically efficient HVAC system.

Effective insulation is essential in HVAC systems to optimize performance and energy efficiency. Duct liner adhesive serves as a binding agent that securely holds the insulation material in place, preventing air leakage and maintaining consistent thermal insulation throughout the ductwork. By reducing heat transfer and minimizing air leakage, duct liner adhesive helps HVAC systems operate more efficiently, resulting in energy savings and improved comfort.

Common Applications of Duct Liner Adhesive

Duct liner adhesive finds wide-ranging applications across various HVAC installations, including:

  • Commercial and residential buildings: In commercial and residential settings, duct liner adhesive is used to line and insulate air ducts, ensuring effective thermal insulation and noise reduction. It is commonly employed in offices, retail spaces, hotels, apartments, and houses, among other structures.
  • Hospitals and healthcare facilities: In healthcare facilities, maintaining clean and sterile environments is critical. Duct liner adhesive helps prevent the growth of mold and bacteria, providing a hygienic solution for duct insulation in hospitals, clinics, laboratories, and cleanrooms.
  • Schools and educational institutions: Educational buildings, such as schools and universities, require efficient HVAC systems to provide a conducive learning environment. Duct liner adhesive helps in reducing noise transmission and improving energy efficiency in educational facilities.
  • Industrial and manufacturing facilities: Industrial and manufacturing facilities often have complex HVAC systems with extensive ductwork. Duct liner adhesive is used to insulate and dampen noise in these environments, contributing to worker comfort and productivity.

Variations of Duct Liner Adhesive

Aeroflex USA offers a range of duct liner adhesives tailored to specific requirements. These variations include:

Solvent-based adhesive:

Solvent-based duct liner adhesive is known for its quick-drying properties, making it ideal for applications that require faster installation times. This adhesive offers excellent bond strength and is suitable for various HVAC projects, including large-scale commercial installations and time-sensitive construction projects.

Low-VOC adhesive:

Low-VOC (Volatile Organic Compounds) duct liner adhesive is designed to meet stringent environmental regulations and indoor air quality standards. This adhesive emits minimal VOCs during application, ensuring a healthy installation environment, and for low chemical emissions post installation. It is a recommended choice for environmentally conscious projects and locations with strict air quality regulations.

These variations of duct liner adhesive provide options for different project requirements, allowing HVAC professionals to choose the most suitable adhesive based on factors such as installation time, bond strength, environmental impact, and indoor air quality considerations.

Technical Specifications and Limitations

To ensure optimal performance and longevity, it is important to consider the technical specifications and limitations of duct liner adhesive. Some key factors to keep in mind include:

Bond Strength:

Aeroflex duct liner adhesive offers exceptional bond strength to securely attach the insulation material to the duct surfaces. This ensures that the insulation stays in place and maintains its effectiveness over time, even in high-pressure airflow conditions.

Temperature Resistance:

Duct liner adhesive should be able to withstand the temperature variations typically encountered in HVAC systems. Aeroflex’s adhesives are formulated to provide excellent temperature resistance, allowing them to perform effectively in both hot and cold environments.

Moisture Resistance:

Moisture can degrade the performance of duct liner adhesive and compromise the insulation system. Aeroflex’s duct liner adhesives are designed to be highly resistant to moisture, ensuring long-lasting insulation integrity even in humid conditions.


Ensure that the adhesive is compatible with the specific insulation material and the surface of the ducts. Aeroflex’s duct liner adhesives are formulated to work effectively with a wide range of insulation materials and duct surfaces, providing a reliable and secure bond.

By considering these technical specifications and limitations, HVAC professionals can make informed decisions when selecting the appropriate duct liner adhesive for their projects, ensuring optimal performance, and long-term durability of the HVAC system.

Acoustic Duct Liner: Enhancing Sound Control

What is Acoustic Duct Liner?

Acoustic duct liner is a specialized type of duct insulation that is specifically designed to provide sound control and reduce noise transmission within HVAC systems. It is composed of a open-cell fibrous or closed-cell non-fibrous material that absorbs and attenuates sound waves, preventing them from traveling through the ductwork and into occupied spaces.

Common Applications of Acoustic Duct Liner

Acoustic duct liner is widely used in various applications where noise control is a priority. Some common applications include:

  • Commercial Buildings: Acoustic duct liner is installed in commercial spaces such as offices, conference rooms, performing arts centers, and theaters to create a quieter and more comfortable environment for employees, customers, and patrons.
  • Hospitals and Healthcare Facilities: In healthcare settings, maintaining a quiet and peaceful atmosphere is crucial for patient recovery. Acoustic duct liner helps reduce noise levels, ensuring a conducive environment for healing and rest.
  • Schools and Educational Institutions: Educational buildings require quiet classrooms and study areas for effective learning. Acoustic duct liner helps minimize noise distractions, improving concentration and academic performance.
  • Residential Buildings: Acoustic duct liner is used in residential HVAC systems to create a peaceful living environment by reducing noise transmission from the ductwork into living spaces.

Variations of Acoustic Duct Liner

Aeroflex USA offers a FIBER-FREE acoustic duct liner product to suit different project requirements and performance needs. Variations include different thicknesses of the non-fibrous material, allowing HVAC professionals to select the most appropriate acoustic duct liner for their specific application, while also meeting energy code requirements.

Technical Specifications and Limitations

When selecting an acoustic duct liner, it is essential to consider the technical specifications and limitations to ensure optimal performance. Some factors to consider include:

  • Noise Reduction Coefficient (NRC): The NRC indicates the sound absorption capability of the duct liner material. Higher NRC values indicate better sound absorption performance.
  • Flame Spread and Smoke Generation: Acoustic duct liner should comply with fire safety standards and have low flame spread and smoke generation characteristics to ensure the safety of the HVAC system and occupants.
  • Installation Considerations: Proper installation techniques are crucial to achieve optimal sound control. Following manufacturer guidelines and industry best practices is essential for maximizing the effectiveness of acoustic duct liner.

By selecting high-quality acoustic duct liner and considering the technical specifications and limitations, HVAC professionals can effectively control noise levels and provide a quieter and more comfortable environment for building occupants.
