Adhesive aluminum tape Tesa 25 mm x 0.05 mm roll

Adhesive aluminum tape Tesa 25 mm x 0.05 mm roll is a thin metallic tape with an adhesive backing designed for sealing, shielding and small surface repairs. The narrow 25 mm width and 0.05 mm thickness make this tape suitable for precise application in HVAC joints, cable shielding, and minor insulation or repair tasks where a slim, conformable metal barrier is needed. The tape provides a quick, adhesive solution for creating an electrically conductive surface and protecting small areas from moisture or air leakage.

Advantages

The tape combines a thin aluminum carrier with an adhesive layer that adheres to metal, plastic and many common building materials. Its narrow width allows for accurate placement in confined or irregular spaces, and the low thickness ensures good conformity to curved or uneven surfaces. The metallic surface offers electrical conductivity and reflective properties while the self-adhesive backing enables fast, single-step application without additional tools.

Suitable for

• Sealing HVAC duct joints and seams
• Shielding cables and cable splices against electromagnetic interference
• Minor insulation repairs and patching small gaps
• Surface protection and temporary repairs on metal or painted surfaces

Key specifications

• Carrier material: aluminum foil
• Adhesive type: pressure-sensitive adhesive
• Width: 25 mm
• Thickness (total): 0.05 mm
• Form: roll
• Surface finish: metallic / reflective

How to use

Clean and dry the surface before application to ensure optimal adhesion. Measure and cut the required length from the roll, then press the tape firmly onto the target area using your thumb or a roller for improved contact. For curved or uneven surfaces, apply gradually and smooth the tape to remove air pockets. Overlap adjacent strips where continuous coverage is needed. For long-lasting seals, ensure edges are firmly pressed down and environmental exposure is considered.

Usage recommendations

Use the tape at moderate temperatures and on clean, dry substrates for best results. Avoid prolonged exposure to direct sunlight or extreme moisture if a permanent seal is required; consider combining with appropriate sealants for heavy-duty or exterior applications. When electrical conductivity is needed, ensure proper contact and continuity between overlapping strips.
