True Aluminium Foil Tape

Multifoil Insulation’s Thermaseal Foil Joining Tape is essential for use with any of our MultiFoil products. When fully taped and sealed it will ensure the Insulation will act as a vapour control layer, resulting in no risk of condensation.

This product is extremely sticky and when fitted correctly will stay in place for the duration of the application. If you are Fixing Thermaseal Foil Joining Tape to wooden battens or brick please ensure that the wood is clean and dust/dirt free.

We recommend using one roll of Thermaseal Foil Tape between every 30m² of MultiFoil. When using on Roofs and Walls it is important that you seal all overlaps, cuttings and the whole perimeter to ensure a complete seal is present.

Watch any of our Installation Videos to see how our ThermaSeal Foil Tape is used with our MultiFoil Products.

Popular products to use our Thermaseal Foil Joining Tape is SuperQuilt and EcoQuilt Expert.

    Does what it says. Super sticky and good coverage per roll. Has a tendency to curl up when removing the backing if you use longer lengths, which can be frustrating, but generally a good product.

    There is a knack to using this as has a tendency to twist and stick to itself. Once you get the knack it does what it says really.
