3M FSK3 Fsk Facing Tape 72mm X 45.7m Foil Scrim Kraft

Product Description

The 3M FSK3 is an aluminum foil-scrim-kraft facing tape designed for sealing and joining FSK insulation facings in HVAC duct and pipe insulation systems. Supplied in 72 mm wide by 45.7 m long rolls, it provides a durable closure and vapor seal on FSK-faced duct wrap and board insulation materials. The tape is rated for a service temperature range of -20 degrees F to 260 degrees F, making it suited for both cold and high-heat insulation applications. HVAC technicians and insulation contractors install this tape as part of code-compliant duct insulation assemblies requiring a sealed FSK facing.

This tape is used in commercial and residential HVAC insulation work where FSK-faced duct wrap, duct board, or pipe insulation requires a proper closure at seams, joints, and butt edges. It is applied in situations where vapor control at the facing is required, including mechanical room and air handler insulation assemblies. Installation is typically performed by sheet metal workers, HVAC technicians, or insulation contractors working on new construction or retrofit duct systems.

Key Features

• Aluminum foil-scrim-kraft construction for durable FSK facing closures
• Service temperature range of -20 degrees F to 260 degrees F
• 72 mm wide format suitable for standard seam and joint coverage
• 45.7 m roll length reduces mid-job splicing on larger duct runs
• Intended for vapor seal and closure applications on FSK-faced insulation systems

Compatibility

Designed for use with foil-scrim-kraft faced duct wrap and insulation materials in HVAC applications. Confirm compatibility with specific insulation systems per official 3M technical documentation before installation.

Installation Notes

Installation is performed by qualified HVAC technicians or insulation contractors following applicable mechanical and energy codes. Ensure the FSK facing surface is clean, dry, and free of dust or debris before applying tape to achieve proper adhesion. Consult 3M technical data sheets for approved substrates and adhesive performance details specific to the installation environment. Do not apply over wet or frost-covered surfaces.
