This is a self-adhesive aluminium foil tape on a 45 m roll, 100 mm wide, with a peel-off paper liner for accurate placement. It is built for HVAC and insulation work: sealing duct seams and end caps, joining foil-faced insulation boards and quilts, and wrapping pipes and vents. The foil reflects radiant heat and light and is flame retardant and moisture resistant, so it suits warm-side insulation joints and weather-exposed seams. Against ordinary duct tape it trades cloth strength for heat and moisture resistance and reflectivity, but it needs a smooth, dust-free surface to bond well.

Aluminium Foil Tape is a self-adhesive sealing and joining tape for HVAC and insulation work. It is made of reflective silver foil. It resists moisture, heat, flame and weather, and it reflects radiant heat and light at joints and seams.
A peel-away backing paper lets you place the tape accurately with fewer wrinkles. It seals on smooth, dust-free surfaces. Uses include joining foil-faced insulation boards and quilts, sealing HVAC ducting seams and end caps, and general sealing around pipes, vents and services.
Clean, dry surfaces free from dust, oil and release agents give the best result. Start by peeling a short section of liner, then press on from the centre outward, removing the liner as you go. Overlap joints by at least 25 mm and press down with a roller or squeegee. The tape is not a structural fixing. Adhesion may be reduced on damp, dusty, textured or low-energy plastic surfaces, so test a small area first. Apply in dry conditions and avoid prolonged water immersion or direct high-temperature flame contact.
