Product Description

Product BriefFSK aluminum foil tape is a high-performance, multi-layer adhesive tape designed for use in HVAC systems, insulation applications, and general construction. Composed of a reflective aluminum foil layer, a strong fiberglass scrim reinforcement, and a stable kraft paper backing, FSK tape provides superior strength, durability, and vapor barrier performance. Its pressure-sensitive acrylic adhesive ensures reliable bonding in both high and low temperature environments, making it ideal for creating airtight, energy-efficient thermal systems.

Key Features• Aluminum Foil Layer: Creates a highly effective vapor barrier, reflects radiant heat, and resists moisture, smoke, and UV light.
• Fiberglass Scrim: Enhances tensile strength and tear resistance, making the tape much more durable than standard foil tape.
• Kraft Paper Backing: Offers structural stability, prevents adhesive blocking during handling, and improves overall product strength.
• Strong Acrylic Adhesive: Provides excellent adhesion to a wide range of surfaces and performs reliably in extreme temperatures.
