Description

Product Overview

Aluminium foil tape combines a thin aluminium foil backing with a pressure-sensitive adhesive, giving it the conductivity and heat-reflective properties of metal foil in a tape format. The foil backing also acts as a vapour barrier and can provide EMI/RFI shielding when the tape maintains electrical continuity across a joint. Adhesive type is the main variable between grades: acrylic adhesives suit general-purpose bonding, while silicone adhesives are typically chosen where higher temperature resistance is required.

Adhesive Specialities supplies aluminium foil tape in acrylic and silicone adhesive variants for HVAC, insulation and shielding applications.

Key Features

• Aluminium foil backing — reflects heat and can provide EMI/RFI shielding across bonded joints
• Available with acrylic or silicone adhesive depending on application temperature
• Acts as a vapour barrier when applied correctly
• Conformable foil surface for sealing irregular duct joints

Applications and Industries

• HVAC — sealing duct joints, insulation facing and vapour barrier applications
• Electronics — EMI/RFI shielding where continuous foil contact is required
• Construction — reflective insulation facing and vapour barriers
• Renewable Energy — thermal and vapour sealing in panel and enclosure assembly

Choosing Silicone vs Acrylic Adhesive Foil Tape

Acrylic adhesive foil tape is the standard choice for general HVAC duct sealing and vapour-barrier work at typical ambient-to-moderate temperatures. Silicone adhesive foil tape is generally selected when the bond needs to hold at higher temperatures or on lower-surface-energy substrates.

Available with silicone adhesive foil tape or acrylic adhesive foil tape, depending on temperature and substrate requirements.

Frequently Asked Questions

What is aluminium foil tape used for?

Aluminium foil tape is used to seal HVAC ducts, provide a reflective heat barrier, and shield against electromagnetic interference (EMI/RFI) when continuous foil contact is maintained across a joint.

Is aluminium foil tape heat resistant?

Heat resistance depends on the adhesive used — silicone adhesive grades are generally chosen for higher-temperature applications, while acrylic grades suit general-purpose use.

What is the difference between acrylic and silicone adhesive foil tape?

Acrylic adhesive is the standard choice for general bonding and duct sealing. Silicone adhesive is typically used where higher temperature resistance or better adhesion to low-surface-energy materials is required.

Can foil tape be used for EMI/RFI shielding?

Yes, aluminium foil tape can provide EMI/RFI shielding, but only where the foil maintains continuous electrical contact across the bonded joint.

Does aluminium foil tape act as a vapour barrier?

Aluminium foil is impermeable to vapour, so foil tape is commonly used to seal insulation facings and create a continuous vapour barrier at joints and seams.
