Foil Tape Insulate HVAC System


Adhesive tape is used for various applications in many industries. Tapes come in wide variety of different types and each of them is designed to serve specific tasks. For example, in the heating, ventilation, and air conditioning system (also called HVAC system), adhesive tape or so called pressure sensitive adhesive tape are used to seal mechanical ventilation systems and insulation joints.

Generally, the kind of tape that will be chosen for specific application depends on four main aspects, say, the surface, the application conditions, the service temperature and moisture conditions, and the specific service requirements.

As for the insulation industry these days, it is a common practice to use fiberglass insulation covered with the vapor and radiant barrier. Since vapor/radiant barrier is, typically, aluminum foil reinforced with kraft paper and fiberglass yarn scrim, another kind of adhesive tape is designed to seal joints of radiant and vapor barrier. Usually, adhesive FSK tape is applied on the similar insulation facing. Thus, FSK tape is used for FSK faced duct wrap, FSK faced duct board, or FSK faced insulation in many types of residential and commercial buildings. Simply speaking, for the normal performance of insulation facing or radiant barrier, every joint has to be sealed with the adhesive FSK tape.

Well, there are many other kinds of adhesive tape used for the air-conditioning, heating, ventilation industry as well as for the insulation. Various types of adhesives provide broad range of application conditions from a very cold (-35 degrees F) temperatures up to very hot temperatures (250 degrees F). There are also flame retardant adhesives, high stick adhesives, etc. There are also many more types of reinforcement, which are designed for different surfaces, applications, insulation facings and radiant barriers. When choosing these products, you can merely depend on your project, and then made an appropriate choice.

For example, foil tape, or the most common aluminum foil tape, is used to seal seams and joints of the sheet metal ducts and their connections to the flexible duct. Foil tape is also often used in the air conditioning to seal joints of flexible ducts to the air grills. So to speak, foil tape in the air conditioning and ventilation industries is used as often as a thread in the garment industry. Whenever you need to join parts and seal the seam from leaks, aluminum foil tape comes handy.
