ThermaSeal Foil Tape 75mm x 50m – True Aluminium Joining Tape for Insulation

ThermaSeal Foil Tape is a high-performance True Aluminium Foil Tape engineered for securely sealing and joining ThermaPack Insulation Rolls and Hydroponics Foil Insulation.

Designed to provide an airtight, moisture-resistant, and professional finish, ThermaSeal Foil Tape helps insulation perform at its highest efficiency. When used to seal overlaps, edges, and joints, it transforms your installation into a continuous vapour control layer, improving energy performance and preventing condensation.

Made from 100% genuine aluminium foil, not metallised plastic, this tape offers exceptional heat reflection and durability. Its high-tack acrylic adhesive ensures a long-lasting bond to clean, dry surfaces and will last the lifetime of the insulation.

The recommended width of 75mm allows easy coverage of seams, corners, and edges. Each 50-metre roll provides enough material to seal approximately 30m² of insulation, making it a cost-effective finishing solution for professional or DIY use.

ThermaSeal Foil Tape is suitable for a wide range of applications, from roofs, lofts, walls, sheds, conservatories, and garden rooms to hydroponic growing systems, wherever reliable insulation sealing is required.

FAQ

What is Thermaseal foil tape used for?

Thermaseal foil tape is a high-performance sealing tape for joining, sealing, and repairing foil and reflective insulation. It is designed to maintain thermal efficiency by creating airtight seals that prevent heat loss, air leakage, and moisture ingress. It is commonly used in insulation installation, packaging, HVAC systems, and construction applications.

Can Thermaseal foil tape be used outdoors?

Yes, Thermaseal foil tape is designed for both indoor and outdoor use. It offers strong resistance to moisture, temperature changes, and UV exposure, making it suitable for exposed insulation applications. This durability ensures long-lasting performance even in demanding environmental conditions.

Is Thermaseal foil tape suitable for HVAC and duct insulation systems?

Yes. Thermaseal foil tape is widely used in HVAC systems, ductwork sealing, and ventilation insulation. It helps create airtight seals around joints and seams, improving system efficiency and reducing air leakage. This supports better temperature control and improved energy performance in heating and cooling systems.

How strong and durable is Thermaseal foil tape?

Thermaseal foil tape features a high-tack adhesive combined with a reinforced aluminium foil backing for strong, long-lasting adhesion. It bonds effectively to a wide range of surfaces, including insulation boards, metal ducting, and foil insulation rolls. This ensures reliable performance in both temporary and permanent insulation applications.

Can foil tape improve energy efficiency?

Yes, Thermaseal foil tape improves energy efficiency by sealing gaps, joints, and insulation seams to prevent heat loss and cold air leakage. Maintaining a tighter thermal envelope, it helps stabilise internal temperatures and reduces the workload on heating and cooling systems, ultimately lowering energy consumption.
