Heating, Ventilation, and Air Conditioning (HVAC) systems are among the most important mechanical components of modern buildings, providing indoor comfort, energy efficiency, and high indoor air quality. These systems consist of air ducts, piping networks, air handling units, ventilation fans, and a wide range of mechanical equipment.
Within HVAC systems, adhesives and sealants are used to prevent air leakage, damp vibration, support equipment installation, and seal service penetrations.
Poorly sealed duct joints or service penetrations can result in energy loss, condensation issues, and reduced system efficiency. For this reason, achieving optimum performance depends not only on selecting the appropriate product but also on applying it correctly.
Products are commonly used in the following HVAC applications:
Air duct joints
Air handling unit (AHU) installation
Duct flange joints
Mechanical equipment connections
Pipe penetrations
Installation of vibration-generating equipment
Rooftop HVAC units
Duct insulation details
Sealing of technical service areas
Maintenance and repair applications.
Technologies Used
Neutral Silicones
Neutral-cure silicones are used in HVAC applications exposed to significant temperature fluctuations and outdoor environmental conditions.
Typical applications include exterior duct penetrations, rooftop equipment, perimeter joints around air ducts, and metal frame connections.
Polyurethane Sealants
Polyurethane sealants are suitable for creating flexible joints in mechanical installations incorporating vibration-generating equipment.
Typical applications include air handling unit bases, structural steel details, and mechanical equipment connections.
Fire-Resistant Acrylic Sealants
Fire-rated acrylic sealants should be used for air ducts and service penetrations passing through fire-rated compartments, in accordance with the requirements of the relevant tested firestop systems.
These applications should always be designed and executed as part of the project's passive fire protection strategy.
Hybrid Polymer Technology
Hybrid polymer-based products are widely used in HVAC applications as both adhesives and sealants.
Their key advantages include excellent adhesion to galvanized steel and pre-painted metals, permanent elasticity, vibration damping, low shrinkage, and UV resistance for exterior applications.
These characteristics make them reliable solutions for ductwork systems and mechanical equipment installation.
