## Summary description

K-flex K-FLEX® ALU AR CW is a reinforced aluminium tape designed for insulation and surface protection. Specified at 25 µm thickness, 50 mm width and 50 m length, it provides a durable metallic facing for thermal insulation joints, vapour barriers and pipe wrapping. Suitable for sealing seams, repairing foil-faced insulation and improving weather resistance in HVAC and refrigeration applications.

## Long description

K-flex K-FLEX® ALU AR CW is a reinforced aluminium tape with a 25 µm metallic foil designed for insulation and surface protection. With a width of 50 mm and a roll length of 50 m, this tape provides a continuous aluminium facing for sealing joints in foil-faced insulation, wrapping pipes and protecting thermal insulation surfaces against moisture and mechanical wear. The product is intended for HVAC, refrigeration and other building services where a durable vapour-tight or weather-resistant layer is required.
Advantages
The tape combines a thin yet reinforced aluminium foil with a pressure-sensitive adhesive to ensure good adhesion to metal, foil-faced insulation and many common building substrates. Its 25 µm thickness balances flexibility and mechanical resistance, allowing it to conform to curved surfaces and pipe bends while providing an effective barrier against vapour and external contaminants. The 50 m length of the roll reduces the need for frequent joins in longer runs.
Suitable for
 Sealing longitudinal and transverse seams in foil-faced insulation
 Wrapping and repairing insulation on pipes and ducts
 Creating vapour barriers and improving weather resistance of external insulation surfaces
 Temporary protection of surfaces during installation and maintenance
Key specifications
 Material: reinforced aluminium foil with pressure-sensitive adhesive
 Foil thickness: 25 µm
 Width: 50 mm
 Length: 50 m per roll
 Surface: metallic aluminium facing suitable for thermal insulation applications
 Flexibility: conforms to curved and cylindrical surfaces
How to use
Ensure surfaces are clean, dry and free of dust, oil or loose particles before application. Measure and cut the required length of tape, then apply by pressing firmly along the length of the seam or wrapped surface to achieve full contact and an even adhesive bond. Smooth the tape with a roller or hand pressure to remove trapped air and improve adhesion, especially around bends and joints. Overlap adjacent strips where continuous coverage is required and trim excess material for neat edges. For long-term external exposure, check compatibility with the insulation facing and consider additional mechanical fastening where necessary.
Usage recommendations
Store rolls in a dry, cool place away from direct sunlight. Apply at moderate ambient temperatures for best adhesion and allow the adhesive to set before subjecting the taped area to mechanical stress or high humidity. For critical vapour barrier applications, inspect joints after installation to verify continuity and re-seal any gaps.
