FSK Tape

FSK tape stands for Foil-Scrim-Kraft tape. It’s a specialized adhesive tape designed to seal and join insulation materials that have a Foil-Scrim-Kraft (FSK) facing. Available in various widths and lengths to accommodate different sealing tasks and insulation board sizes.

Foil-Scrim-Kraft (FSK) is a type of laminate composed of aluminum foil, scrim, and Kraft paper. This combination provides a robust barrier that is highly effective in both thermal insulation and vapor control. The tape is coated with a high-performance acrylic adhesive that ensures strong bonding and long-term durability, even under varying environmental conditions.

By effectively sealing joints and seams, FSK tape helps maintain the integrity of the insulation’s thermal barrier. The aluminum foil layer acts as an excellent moisture barrier, reducing the risk of mold and mildew development. The combination of materials makes FSK tape very durable, capable of withstanding chemical exposure, high temperatures, and humidity. The tape is easy to apply and requires no special tools, making it convenient for quick repairs and installations.
