Aluminium Tape

Aluminium tape, also known as alu tape or foil tape, provides watertight sealing, lasting adhesion, and heat resistance, withstanding temperatures of up to 150°C or more, depending on the grade. 

This essential finishing touch for ductwork and insulation is a favourite among UK builders, HVAC installers, and DIY users alike.

What Is Foil Tape? 

Foil tape, sometimes called alu tape, aluminium foil adhesive tape, or tape for aluminium surfaces, is a specialised sealing tape made from aluminium foil backed with a strong adhesive. 

It securely sticks to surfaces exposed to vibration, heat, or moisture, where ordinary tapes lose adhesion. The tape’s adhesive backing ensures a long-term grip on various materials, including insulation boards, vapour barriers, ducting, plastic, and metal surfaces. The reflective foil layer provides excellent resistance to light and heat.

What Is Foil Insulation Tape Used For?  

A versatile binding tape for aluminium ducts, vapour control layers, and insulation, foil insulation tape securely joins and seals materials. Typical applications include:

• Sealing lagging and pipework.
• Sealing joints in foil-faced insulation boards and reflective rolls.
• Improving airtightness by closing seams and gaps.
• Patching tears in vapour barriers and foil surfaces.
• Wrapping and repairing ductwork in HVAC systems.
• Reflecting heat in thermal or radiant insulation systems, standard in roof and HVAC applications.

FAQ

What is aluminium tape used for?

Alu tape is ideal for sealing insulation joints, air ducts, and reflective foil surfaces, making it the perfect tape for aluminium and other metal surfaces. It is typically applied where moisture protection, heat resistance, or airtightness are crucial.

What is aluminium foil tape?

Alu foil tape is a multipurpose, reflective tape produced from aluminium foil. It provides strong adhesion, high thermal resistance, and a professional metallic finish for HVAC and insulation applications.

How to use aluminium tape

Ensure the surface is clean, dry, and free from dust. Remove the backing, then place the tape smoothly along the joints or seams, pressing firmly to create a tight seal. Apply in dry conditions above 10°C for optimal adhesion. Use a roller or squeegee to remove air bubbles. 

How to remove aluminium tape

Carefully lift one corner of the tape and then peel it back slowly. Any leftover residue can be cleaned with a mild solvent or adhesive remover. Test the solvent on a small area first and use a heat gun on a low setting to soften the adhesive if needed. Use protective gloves when handling heat guns to prevent burns.

How much is aluminium tape?

On average, aluminium foil tape rolls in the UK range from £4 to £15. The exact cost depends on size, performance rating, and brand. View our full range of aluminium tapes for current pricing.
