Vybond 1087653 Fsk Tape 3 Inches X 60 Yards

Product Description

The VYBOND 1087653 is a diamond-pattern FSK (Foil/Scrim/Kraft) tape designed for sealing and securing insulation in HVAC and mechanical insulation applications. The three-layer construction combines an aluminum foil face, fiberglass scrim reinforcement, and a kraft paper backing to deliver a durable, vapor-retarding seal on duct wrap, duct board, and pipe insulation. At 3 inches wide and 60 yards per roll, a single roll covers substantial linear footage on a jobsite, making it a practical choice for both new construction and retrofit insulation work. HVAC technicians and insulation contractors are the primary installers.

FSK tape is standard on residential and commercial HVAC ductwork insulation, particularly where a vapor barrier seal is required at seams, butt joints, and longitudinal laps of fiberglass duct wrap or rigid duct board. It is also used on mechanical pipe insulation in plenum and non-plenum environments. The diamond scrim pattern adds tensile strength across both axes of the tape, reducing the risk of tearing during application in tight or confined spaces.

Key Features

• Three-layer FSK construction: aluminum foil face, fiberglass scrim, kraft paper backing
• Diamond scrim pattern for balanced tensile strength in both directions
• 3-inch width covers standard insulation seams and lap joints efficiently
• 60-yard roll length reduces mid-job roll changes on large projects
• Vapor-retarding face layer suitable for HVAC insulation sealing

Compatibility

Designed as a standard FSK seam tape for use with fiberglass duct wrap insulation, rigid duct board, and faced pipe insulation in residential and commercial HVAC mechanical systems.

Installation Notes

FSK tape is applied by HVAC technicians and insulation contractors as part of ductwork insulation sealing. Shut down the air handling system before sealing duct insulation seams to prevent dust contamination of adhesive surfaces. Surfaces should be clean, dry, and free of oil or dust before tape application to ensure full adhesion. Follow local mechanical codes and SMACNA guidelines for insulation seam sealing requirements.
