FSK Insulation Tape

• Tape Description

  This heavy-duty aluminum foil tape features a multi-ply backing consisting of aluminum foil, flame-retardant kraft paper, and a reinforcing fiberglass scrim, all laminated together with a high-performance adhesive. This unique construction serves as an effective flame-retardant vapor barrier, making it one of the most reliable facings used in the insulation industry to stop vapor transmission and air leakage.

  The primary function of FSK insulation tape is to create airtight seals and joints in HVAC setups, preventing energy loss and optimizing thermal performance. It is commonly used to seal the seams and edges of foil-scrim-kraft-faced fiberglass duct boards and pipe insulation. Additionally, it provides structural reinforcement when used with fiberglass duct wraps and acts as an efficient patch for rips and tears in foil-facing insulation. Despite its rugged strength, the tape is designed to be easily torn by hand, offering maximum convenience during complex installations.

• Features & Benefits

  • Superior Moisture & Vapor Barrier: The aluminum foil and kraft backing protect against moisture penetration, effectively preventing the growth of mold and mildew within ductwork.
  • Thermal Resistance: The reflective properties of the foil layer help reflect heat, prevent heat loss, and maintain strict temperature control across various systems.
  • High Durability & Tear Resistance: Embedded fiberglass scrim adds incredible strength, ensuring the tape withstands tough environmental conditions without degrading.
  • Strong, Reliable Adhesion: The high-performance adhesive delivers a secure, long-lasting bond to metal surfaces, fiberglass duct boards, and insulation blankets.
  • Flame-Resistant Safety: Engineered with flame-retardant components to meet critical safety requirements in residential and commercial HVAC applications.

• Applications

  FSK Insulation Tape is a versatile product relied upon across multiple trades, including:

  • HVAC Systems: Sealing joints, seams, and ductwork in heating, ventilation, and air conditioning networks to eliminate air leakage.
  • Piping & Duct Insulation: Wrapping insulated pipes to prevent heat loss or gain and secure insulation blankets in place.
  • Building & Construction: Sealing insulation joints within walls, roofs, and floors to enhance overall building energy efficiency.
