Aluminum Foil Tape Description


The reinforced aluminum foil tape consists of a layer of aluminum foil on one side, which provides heat reflection and moisture barrier properties. The foil is often reinforced with a scrim (a type of fabric) for added strength and durability. The other side of the tape have a layer of kraft paper, which helps with adhesion and provides a surface for writing or labeling. FSK foil tape different to foil fiberglass cloth tape. They are both reinforced aluminum tape that have different structure. Scrim is superior to other fabrics because the fibers are not crimped. Scrim is strong, flexible, and can be fire retardant.

The Foil-scrim backing is 18um aluminum foil laminated with the 2-way scrim 5x5mm. The scrim formed by a set of fiberglass yarns, in a transverse arrangement, where these are spaced from each other at a distance of 5mm. FSK foil tape is highly resistant to temperature changes, UV radiation, and chemicals, making it an ideal choice for use in demanding environments such as industrial facilities, commercial buildings, and residential homes.

FSK foil tape is used to seal joints, seams, and connections in HVAC ductwork to prevent air leakage and improve energy efficiency. It is also used for insulation applications where a vapor barrier is needed. The tape is durable, heat-resistant, and easy to apply, making it a popular choice in the HVAC industry for various sealing and insulating needs

Tape Applications:

  • FSK foil tape applied for the coating and insulation in the air conditioning and ventilation sector.
  • General patching, sealing and fastening applications.
  • Union of fiberglass sheets or duct joints.
  • Insulation sealing of cold rooms.
  • Recommend use as sheet metal duct water vapor seal.
  • Rigid insulation of closing air ducts.

Tape Features:

  • Excellent level of adhesion and performance at higher temperatures.
  • High-strength foil-scrim laminate backing resists tearing.
  • High quality adhesive capable of bonding on a wide variety of substrates in cold climates.
  • High-tack synthetic rubber adhesive forms an instant bond.
  • Vapor barrier, reflecting heat, reflecting light, and UV-resistant design.
