Aluminum Foil Tape AWTools AW26230 48 mm × 50 m, heat-resistant, conductive

AWTools Aluminum Foil Tape AW26230 48 mm × 50 m is a self-adhesive metal tape designed for sealing, patching and reflecting heat in heating, ventilation and air-conditioning (HVAC) systems, ductwork and thermal insulation applications. The tape combines a metal foil carrier with a pressure-sensitive adhesive to provide a durable, conductive and heat-resistant layer that supports electrical shielding, surface protection and moisture-resistant joints. Its 48 mm width and 50 m length make it suitable for continuous runs or spot repairs in both professional and DIY projects.

Advantages

The aluminum foil construction offers thermal reflectivity and inherent corrosion resistance while the conductive adhesive layer supports electrical continuity for shielding and grounding. The tape adheres to metal, insulation facings and many building materials, forming a stable seal that resists temperature changes and air leakage. Its conformable nature allows it to follow curved or irregular surfaces, and the product is sized to balance ease of handling with coverage efficiency.

Suitable for

• Sealing and joining HVAC ducts and ductboard seams
• Patching insulation facings and vapor barriers
• Reflecting heat from surfaces and preventing radiant heat transfer
• Electrical shielding, grounding and EMI/RFI mitigation tasks
• Repairing metal surfaces, flashing and reflective barriers

Key specifications

• Material: aluminum foil carrier with pressure-sensitive adhesive
• Width: 48 mm
• Length: 50 m
• Properties: heat-resistant, conductive, moisture-resistant sealing
• Surface: conformable to curved and irregular substrates

How to use

Ensure surfaces are clean, dry and free from dust, oil or loose particles before application. Measure and cut the required length, then press the foil tape firmly onto the surface, smoothing from the center outward to remove air pockets and ensure full contact. For best adhesion, apply consistent pressure along the tape using a roller or firm hand pressure. Overlap seams where necessary to create continuous coverage and improve sealing performance. Use appropriate personal protective equipment when working near sharp metal edges or hot surfaces.

Usage recommendations

Store the tape in a dry environment away from direct sunlight and extreme temperatures. For long-term or structural sealing on critical systems, inspect applied tape periodically and reapply or replace when adhesion degrades. Do not use the tape as the sole method of mechanical support where load-bearing is required.
