- About
Widely used throughout the HVAC and insulation industries, FSK Tape (Foil-Scrim-Kraft Tape) and ASJ Tape (All Service Jacket Tape) are the two most common types of reinforced aluminum foil tapes. While both products serve similar structural and vapor sealing purposes, they are specifically designed to match different insulation facings and application environments. Designed to withstand harsh environmental conditions, these tapes offer excellent resistance to tearing, lifting, curling, humidity, UV exposure, and temperature fluctuations while maintaining strong adhesion on insulation facings and duct systems.
Whether sealing HVAC ductwork, pipe insulation systems, reflective insulation, or thermal barriers, these Reinforced Aluminum Foil Tape helps improve insulation efficiency, reduce condensation risks, and extend system lifespan.
A silver, metallic laminate combining an aluminum foil top layer, a bi-directional fiberglass mesh scrim, and a durable structural kraft paper backing.
Key Features: It is highly resistant to tearing, offers excellent thermal insulation properties, and uses a cold-weather acrylic adhesive so it won't peel off when temperatures drop.
Common Uses: Sealing seams on HVAC ductwork insulation, patching tears in reflective insulation, and wrapping high-temperature pipes.
A tri-directional reinforced laminate featuring a clean, white-bleached kraft paper or polymer top layer, a reinforcing fiberglass mesh scrim, and an inner aluminum foil vapor barrier.
Key Features: The defining feature of ASJ tape is its clean, white appearance. It blends seamlessly with ASJ-faced fiberglass pipe insulation, providing a professional, finished look without needing to be painted. It also maintains a zero-permeability vapor barrier to prevent pipe sweating.
Common Uses: Sealing joints and elbows on chilled or hot water pipe insulation, especially in exposed areas (like mechanical rooms or commercial ceilings) where aesthetics and a neat finish matter.
Both variations utilize high-performance pressure-sensitive adhesives protected by an easy-release silicone liner to ensure rapid, clean handling and maximum structural bond longevity on the job site.

Scrim-reinforced PE single-sided air sealing tape for OSB, plywood & membranes, designed for creating long-lasting airtight, moisture-resistant, and weatherproof seals
A: While both are high-strength variations of Reinforced Aluminum Foil Tape, they are designed to match distinct insulation facings. Foil-Scrim-Kraft Tape features a silver metallic finish optimal for sealing foil-faced duct wraps, rigid duct boards, and reflective bubble insulation. ASJ tape, or All Service Jacket Tape, features a heavy-duty white outer layer designed to match white-jacketed pipe insulation networks.
A: Yes. Despite their multi-layer mechanical reinforcement, our tapes apply easily to irregular, curved, or uneven geometric profiles without lifting or peeling.
A: No. The bi-directional or tri-directional fiberglass mesh layer provides outstanding puncture and tear resistance while in service, but when paired with our premium pressure-sensitive adhesive and release liner, it handles cleanly and cuts efficiently on the job site.
A: Our ASJ tape integrates an inner aluminum foil layer that maintains a zero-permeability vapor barrier, keeping moisture away from cold-water piping systems to prevent condensation and pipe sweating.
A: The scrim is a middle layer of bi-directional or tri-directional fiberglass mesh. It acts as a structural backbone, allowing the tape to bend cleanly with the primary insulation facing while providing the high tensile strength required to prevent tearing under pressure.
A: No. Our reinforced tapes are formulated with weather-resistant pressure-sensitive adhesives—such as cold-weather acrylics—ensuring they deliver solid holding power and resist lifting even under severe temperature fluctuations.
