Diamond® FSK Tapes

Diamond FSK Tape is a combination of Aluminum Foil, Scrim & Kraft Paper coated with a high performance adhesive and protected by an easy release silicone paper liner for specialized HVAC insulation applications. Diamond FSK Tape is available in two types: Rubber based and Solvent-based.

  • FSK backing provides a strong reinforcement and an excellent reflection of both heat and light.
  • The aggressive adhesive offers long service life in outdoor as well as high humidity atmosphere.
  • Suitable for masking in electroplating aluminum due to its non-contamination properties.
  • The high-strength adhesive gives strong adhesion and holding power that provides a reliable and durable joint & seam sealing in insulation applications.
  • For joining foil faced & rock wool insulation
  • For laminating parts of an air conditioning ducting system.
  • For roofing applications like flashing, joints and insulations.
  • Used for sealing and joining ducts which provides an excellent vapor barrier in refrigeration applications.
  • For general purpose holding, patching sealing applications for indoor.
