True Aluminium Foil Tape

ThermaSeal Foil Joining Tape is a True aluminium Foil Tape designed to fix all of our Multifoil Insulation Materials. Products used with this ThermaSeal Foil Tape include

EcoQuilt Expert,

EcoQuilt Expert is a 6 layer multifoil Insulation. Commonly used to insulate Walls, Lofts, Conservatories and Garden Rooms.
Commonly purchased by DIY’ers and is equivalent to around 100mm of Loft Fibre.

YBS SuperQuilt,

YBS SuperQuilt is the highest performing EN certified Multifoil on the market. Uses for this product include Loft Conversions, Extensions and New Building.
With 19 layers of refelctive foils and waddings, SuperQuilt is equivalent to around 80mm of PIR insulation in a wall detail.


BreatherFoil FR is installed externally of OSB Boards on timber framed buildings and also acts as a high performance venting membrane.
A higher performing alternative to using TF200 and supplied in 2 different roll sizes.

When fully taping and sealing Multifoil Insulation materials in a Roof, Loft Space, Wall, Garden Building or Conservatory this helps the products act as high performing Vapour Control Layer.

We recommend purchasing one roll of Foil Tape for every 30 square meters of Multifoil Insulation.

Ecohome Insulation’s Foil Tape comes on 75mm x 50m Rolls and has a high tack adhesive which will last the lifetime of the application when installed on a dry, clean surface.

For any further fixing instructions, please see the fitting and data sheets on our multifoil product pages.

Free Gifts Include: Thermaseal Foil Joining Tape, Heavy Duty Staple Gun Kit, Multifoil Insulation Scissors or Thermaseal Double Sided Tape.

Genuine True Aluminium ThermaSeal Foil Joining Tape is designed to be used with all Multifoil Insulation materials. ThermaSeal Foil Joining Tape is supplied in one size of 75mm wide x 50 Metre long. 75mm width tape is the recommended width designed to seal overlaps and the edges when fitting Superquilt, EcoQuilt Expert or Airtec Double Insulation.

You should Always Tape and Seal all of our Reflective Insulation Products for Walls and Roofs using ThermaSeal Foil Sealing Tape. When insulating floors we recommend to tape only around the perimeter, leaving the 50mm overlaps untaped – this will prevent moisture from building up.

This will improve the Thermal Performance and also prevent the need for an additional Vapour Control Layer in Certain applications. Please be aware it is not recommended to use cheap Polymer based tape that looks like aluminium foil as this can reduce performance and void the Lifetime Guarantee we provide on our SuperQuilt Insulation.

PLEASE NOTE: For Orders of 2 Rolls of SuperQuilt or EcoQuilt Expert we recommend 1 Roll of Foil Joining Tape, however you may need 2 Rolls in some applications where there are a lot of Cuts and Edges to fully tape and seal. All information is for Guidance purposes.
