True Aluminium Foil Tape

We advise customers to use Thermaseal Foil Joining Tape alongside our multifoil insulation range unless otherwise advised for a specific application.

Why use Thermaseal Foil Joining Tape?

  • It is 75mm x 50m. The width of the roll ensures that you do not have the unwanted passage of air and moisture. Instead, it means that you can cover the joints easily, as it overlaps on each layer.
  • This foil used on the outer layer is true aluminium foil, as opposed to other lookalike foil tapes. These are often made from Metalized Plastics, which are not as reflective.
  • The adhesive on the Tape is also high tack. It has been designed to last the lifetime of the application (when fixed to a clean and dry surface).

How many rolls will you need?

In terms of what you will need – we advise our customers to purchase one roll of Tape – for every 30 square meters worth of Multifoil Insulation. As a general rule of thumb, we advise 1 Roll of Foil Joining Tape for every 2 Rolls of Insulation.

It is often used alongside; EcoQuilt, SuperQuilt, YBS Airtec Double

  19. Christopher (verified owner)

    Great finishing product that adheres really well to the super quilt and the PVCu surface of my conservatory. Take your time when smoothing out the tape because tears can be a problem but it is to be expected with foil this thin. Overall a great product.
