## Summary description

Reinforced aluminum tape K‑flex ALU AR CW is a foil tape with a 25 µm aluminum layer, 75 mm width and 50 m roll length (MPN 85NRCL75050AR18). Designed for sealing, vapor barrier and insulation finishing on ductwork, pipes and HVAC systems. Features reinforcement for increased tear resistance and good conformability for curved surfaces.

## Long description

Reinforced aluminum tape K‑flex ALU AR CW is a foil tape with a 25 µm aluminum layer, 75 mm width and 50 m roll length designed for sealing, vapor barrier and finishing insulation on ductwork, pipes and HVAC systems. The tape combines an aluminum facing with an internal reinforcement that increases tear resistance while maintaining good conformability around curved surfaces and irregular profiles.
Advantages
The reinforced construction provides higher tensile strength and reduced risk of tearing during application compared with non‑reinforced foil tapes. The 25 µm aluminum layer offers effective vapor and light barrier properties and supports easy contact welding or mechanical fastening where required. The tape’s adhesive system is formulated for secure adhesion to metal, insulated surfaces and many common HVAC materials, enabling reliable long‑term joints and seams.
Suitable for
 Sealing longitudinal and circumferential seams on ductwork
 Forming a vapor barrier on insulated pipes and fittings
 Repairing minor damage to insulation jacketing and foil facings
 Fixing and finishing insulation edges and overlaps
 Temporary or permanent repairs in HVAC installations
Key specifications
 Aluminum layer thickness: 25 µm
 Tape width: 75 mm
 Roll length: 50 m
 Reinforced foil construction for improved tear resistance
 Conformable to curved surfaces and irregular profiles
 Adhesive suitable for metal and common insulation facings
How to use
Ensure surfaces are clean, dry and free of dust, oil or loose particles before applying the tape. Measure and cut the required length, peel the release liner (if present) and apply the tape along the joint or seam with even pressure to ensure full contact. For best adhesion, use a firm roller or hand pressure to remove any trapped air and to conform the tape to bends and corners. Overlap tape edges where continuous vapor barrier coverage is required. On outdoor or exposed runs consider additional mechanical fastening or protective jacketing as appropriate to the installation environment.
Usage recommendations
Store rolls in a dry, shaded area at moderate temperature to preserve adhesive performance. Apply at temperatures recommended for typical aluminum foil tapes (above freezing) and avoid stretching the tape excessively during application to maintain barrier integrity and reinforcement performance.
