What is 50mm Aluminium Foil Tape?
50mm Aluminium Foil Tape is a pressure-sensitive adhesive tape composed of a soft, malleable aluminium foil backing coated on one side with a durable adhesive.
The 50mm width makes it suitable for covering larger joints and surfaces, while the 45-metre roll length offers a substantial quantity for various projects.
This type of tape is engineered to provide excellent sealing, joining, and reflective capabilities in a range of environments. Most notably, it is used to seal the joints and seams of Polyisocyanurate (PIR) insulation boards and other foil-faced insulation materials.
Its excellent conformability allows it to adhere tightly to the board surfaces, creating a continuous, airtight, and vapour-resistant barrier. This helps to maintain the thermal integrity of the insulation system and prevents condensation.
Applications
This 50mm Aluminium Foil Tape is a versatile choice for critical sealing and joining tasks, especially valued where a durable, reflective, and moisture-resistant barrier is needed. Its conformability and strong adhesion are key to its performance in these primary applications:
- Joining Foil-Faced Insulation Materials: Ideal for sealing joints and seams on all types of foil-faced insulation, including PIR (Polyisocyanurate) boards and foil-faced mineral wool products. It ensures a continuous vapour barrier, maintains thermal integrity, and prevents air leakage.
- Pipe Lagging: Excellent for securing and sealing the outer layer of pipe insulation (lagging), especially foil-faced types. It protects the insulation, provides a neat finish, and helps maintain the vapour barrier, which is crucial for cold pipework.
- Sealing Ventilation Ducts (HVAC): A principal use is creating airtight seals on joints, seams, and connections in both rigid and flexible ventilation and air conditioning ductwork. This prevents air loss, improving system efficiency and energy conservation.
Other Common Uses:m
- General HVAC & Metalwork: Sealing other components within HVAC systems or general metal-to-metal joints where an airtight or moisture-resistant seal is required.
- Containment Sealing Support: Often used to seal seams in polythene sheeting for temporary containment enclosures (e.g., in asbestos abatement or dust control areas). Users must always verify suitability against all specific project and regulatory requirements for such critical tasks.
- Reflective Shielding & Repairs: Suitable for creating heat shields and for temporary durable repairs on metallic surfaces.
Benefits
- Reflective Aluminium Backing: Foil surface reflects both heat and light, making it useful for thermal insulation applications and creating reflective barriers.
- Vapour & Moisture Barrier: Continuous aluminium foil backing provides an excellent barrier against moisture, vapour, dust, and many airborne contaminants when properly applied.
- Good Thermal Conductivity: Aluminium itself is a good conductor of heat, which can be beneficial in applications requiring heat dissipation or uniform temperature distribution.
- Wide Temperature Tolerance: Aluminium foil can withstand a broad range of temperatures, from very low to moderately high.
- Conformable & Malleable: Soft, flexible nature allows the tape to conform well to irregular shapes, curved surfaces, and tight corners.
- Durable & Long-Lasting: Resistant to ageing, weathering (in certain applications), UV exposure (foil component), and many common chemicals, contributing to a long service life.
- Ease of Application: Simple to cut to length, handle, and apply without the need for special tools beyond a cutting blade.
