FSK Foil Tape

FSK foil tape is a type of pressure-sensitive insulation tape that is made with a foil/scrim/kraft (FSK) backing. FSK foil tape, also known as FSK facing tape or FSK insulation tape, The acronym FSK stands for Foil/Scrim/Kraft. The foil provides a barrier against heat and moisture, the scrim adds strength and tear resistance, and the kraft backing provides a smooth surface for the adhesive to adhere to.

FSK foil tape is primarily used for sealing and joining FSK-faced insulation materials. It is commonly used to seal the seams and joints of ductwork, pipes, and other HVAC components to prevent air leakage and ensure proper insulation performance. The adhesive used on FSK foil tape is typically a high-performance acrylic adhesive that provides strong adhesion to various surfaces, including metal, insulation materials, and other commonly used building materials.
