What is FSK Tape Used for and How it Work?

Posted on February 26th, 2024

FSK tape, also known as Foil-Scrim-Kraft tape, is a type of adhesive tape specifically designed for sealing and joining insulation materials that have FSK facing. FSK tape is commonly used in HVAC systems and other applications where thermal insulation is employed. It plays a crucial role in maintaining the integrity and effectiveness of the insulation system.

What is FSK Tape Used for?

1. Sealing Insulation Joints: FSK tape is primarily used to seal and join the seams and joints of insulation materials that have Foil-Scrim-Kraft facing, such as fiberglass duct boards or insulation blankets. These seams and joints can be vulnerable to air leakage, which can compromise the thermal efficiency of the system. These tapes provides a strong and durable seal to prevent air infiltration and heat loss.

2. Vapor Barrier Protection: FSK tapes helps to maintain the vapor barrier properties of the Foil-Scrim-Kraft facing. The tape creates a continuous barrier that prevents the movement of moisture or water vapor through the joints and seams. This is crucial for preventing condensation and moisture-related issues within the insulation system.

3. Reflective Heat Barrier: FSK tapes reinforces the reflective heat barrier provided by the Foil-Scrim-Kraft facing. The aluminum foil layer in the  tapes reflects radiant heat, helping to reduce heat transfer and improve energy efficiency.

4. Easy Application: FSK tape is designed for easy application. It has a strong adhesive backing that allows it to adhere firmly to the FSK facing and other surfaces. The tape is flexible and can conform to irregular shapes and contours, making it suitable for various insulation applications.

How FSK Tapes Work?

FSK tape is commonly used in HVAC ductwork, where it is applied to seal the joints between duct sections, ensuring a tight and efficient system. It is also used to seal and join insulation materials in walls, roofs, and other areas where thermal insulation is necessary.

When applying FSK tapes, it is important to ensure that the surfaces are clean, dry, and free from dust or debris. The tape is typically applied by pressing it firmly onto the FSK facing or the insulation material joints, ensuring a secure bond. The tape should be applied in a continuous manner to create an effective seal.

FSK facing with insulation systems work by reducing radiant heat gain. To be effective, the Aluminum foil reflective surface must face an air space. Dust accumulation on the reflective surface will reduce its reflective capability. The tape should be installed in a manner to minimize dust accumulation on the reflective surface.

It’s worth noting that FSK tape is specifically designed for use with FSK facing and may not be suitable for other types of insulation or applications. It is important to follow the manufacturer’s instructions and guidelines for proper installation and use of FSK tape.
