Product Information
Full details
The Walther Strong HD Aluminium Foil Tape is a professional-grade solution designed for contractors and DIY enthusiasts working on HVAC systems, insulation, and ductwork projects. This tape offers a superior water-resistant vapour seal and excellent thermal conductivity, helping to improve energy efficiency by reducing cold bridging. While it provides exceptional durability and chemical resistance, users should note that its heavy-duty adhesive is extremely aggressive and can be difficult to reposition once applied to a surface.

FAQs
Is this tape suitable for outdoor use?
Yes, the heavy-duty aluminium layer and moisture-resistant adhesive make it suitable for various outdoor applications, though it performs best when protected from direct, prolonged UV exposure.
Can I paint over this tape?
The metallic surface is not designed for painting. If aesthetics are a concern, it is recommended to apply the tape behind finished cladding or insulation layers.
What is the operating temperature range?
The tape is designed to withstand standard HVAC operating temperatures; however, it should not be applied directly to high-heat sources like open flames or boiler exhaust pipes.
Does it work on flexible ducts?
Yes, it is effective for sealing flexible ductwork, provided the joint is supported and clean.
How do I remove the tape if I make a mistake?
Because of the aggressive adhesive, removal can be difficult. You may need a heat gun on a low setting or a citrus-based adhesive remover to dissolve the residue.
Troubleshooting
Tape is not sticking properly to the surface.
Clean the surface thoroughly with a degreaser or alcohol to remove dust, oil, or moisture, then re-apply using firm pressure.
The tape edges are curling during installation.
Ensure the tape is pulled straight from the roll and that the application surface is flat; avoid stretching the tape during application.
Difficulty unrolling the tape from the spool.
Ensure the roll is stored at room temperature, as extreme cold can make the adhesive stiff and the roll difficult to unwind.

Setup, Compatibility & Care
To achieve the best results, ensure the surface is dry, clean, and free from loose particles before application. Simply pull the desired length of tape from the roll, position it over the joint, and apply firm, consistent pressure with a smooth tool or your hand to activate the adhesive.
Compatibility: This product is specifically designed for use on metal ducting, rigid foam boards, and fibreglass duct boards.
Storage: Store in a cool, dry place away from direct sunlight to preserve the integrity of the adhesive layer. Keep the roll wrapped or in its original packaging when not in use to prevent the edges from picking up debris.
