HVAC tape is Aluminum foil duct tape designed for use in heating, ventilation, and air conditioning (HVAC) systems. It is commonly used to seal joints and seams in ductwork, as well as to provide insulation and prevent air leaks.
HVAC tape typically consists of a flexible backing material, such as aluminum foil or reinforced foil, coated with a strong adhesive. The backing material is often resistant to moisture, heat, and chemicals, making it suitable for the demanding conditions found in HVAC systems. The adhesive provides a secure bond and helps to maintain the integrity of the seal.
The primary purpose of HVAC tape is to create an airtight seal between ductwork components, such as sections of metal ducts or flexible ducting. By sealing the joints and seams, HVAC tape helps to prevent air leaks, which can result in energy loss, reduced system efficiency, and poor indoor air quality. It can also be used to provide insulation, particularly when applied to ducts in unconditioned spaces.
HVAC Tape Selection Guide
HVAC tape is available in a variety of types, from different adhesives to different backing materials.
- Synthetic rubber resin adhesive, also known as hot melt.
- Water based acrylic adhesive.
- Solvent-based acrylic adhesive.
The standard HVAC tape is made of pure aluminium foil, the foil thickness from 18um to 150um. But the thicker the foil, the more expensive it is. So the actual common thickness is up to 50um.
We usually use reinforced aluminium foil to increase its tensile strength but not much production cost.
Reinforced Aluminum Foil HVAC Tape
- FSK tape
- Aluminum foil glass cloth tape
- Foil scrim tape
- PET laminated foil tape
The table below shows the features of HVAC aluminium foil tapes, as well as the technical information for each type.
