Extreme Temperature Aluminium Foil Tape - 45m x 50mmExtreme Temperature Aluminium Foil Tape

Extreme Temperature Aluminium Foil Tape is a professional-grade sealing and joining tape for HVAC and insulation work where wide service temperatures and reliable adhesion are essential. It installs cleanly thanks to a peel-away liner and provides a durable, weather-resistant seal on smooth, dust-free surfaces. Service range −35 °C to +120 °C. 

Key Features & Benefits

• Wide Temperature Range: Suitable for cold and warm applications from −35 °C to +120 °C. 
• Weather & Moisture Resistant: Helps create long-lasting, air-tight seams on ducts and foil-faced insulation.
• Clean Application: Peel-off release paper enables accurate placement with fewer wrinkles.
• Reflective Foil Face: Assists with radiant heat reflection at joints and seams.

Instructions for Use

1. Ensure substrates are clean, dry and free from dust, oil and release agents.
2. Measure and cut the tape; peel a short section of the liner to start.
3. Apply with firm, even pressure from the centre outward; remove the liner progressively to avoid creases.
4. Overlap joints by at least 25 mm; press down with a roller or squeegee for best adhesion.

Limitations & Precautions

• Not a structural fixing; do not use where mechanical fastening is required.
• Adhesion may be reduced on damp, dusty, textured or low-energy plastics—test small areas first.
• Apply in dry conditions; avoid prolonged water immersion or direct flame contact.
