3M™ Venture Tape ™ FSK Facing Tape 1525CW
3M™ Venture Tape FSK Facing Tape 1527CW is a high-performance foil/scrim/kraft (FSK) tape engineered for insulation system sealing, vapor barrier applications, and facing repairs. Designed to work with FSK-faced duct board and blanket insulation, 3M 3320 bonds quickly to a variety of insulation materials and provides a reinforced surface with excellent moisture resistance, tear strength, and thermal stability. The kraft component adds rigidity, while the aluminum foil layer reflects heat and helps maintain energy efficiency.
Applications include: Sealing joints and seams on FSK-faced duct board and fiberglass blanket insulation, repairing damaged FSK insulation facings, vapor barrier integrity, thermal insulation wrap.
- Adhesive can bond in temperatures as low as -10°F (-23°C)
- Reinforced structure for added tear strength and durability
- Excellent moisture resistance and vapor barrier integrity
- Bonds quickly to FSK-faced insulation materials
- Ideal for sealing, repairing, and insulating duct and blanket systems
