Novia Double Sided Butyl Tape is a high-performance jointing and sealing tape designed for use with Novia Air and Vapour Control Layers (AVCLs), Vapour Control Layers (VCLs), Damp Proof Membranes (DPMs) and Gas Barriers. It provides very good adhesion and is used to seal membrane joints and overlaps against air and water vapour ingress.
The tape is designed to form the primary seal within membrane overlaps and should be used in conjunction with an appropriate Novia Metallised BOPP Tape or Aluminium Foil Tape as the final secure seal.
Novia Double Sided Butyl Tape is available in two sizes:
The tape is not designed to act as a load-bearing element. AVCL and DPM installations must therefore also incorporate the appropriate mechanical fixings.
Key benefits include:
Novia Double Sided Butyl Tape is designed for jointing and sealing compatible building membranes where protection against air and water vapour ingress is required.
Typical applications include:
It forms part of the Novia membrane sealing system rather than being a general-purpose structural fixing product.
Novia Double Sided Butyl Tape is positioned between overlapping membrane sheets.
Its double-sided construction bonds the adjoining membrane surfaces together, helping create a continuous seal across the overlap.
The installation should then be completed using the appropriate Novia single-sided sealing tape specified for the membrane.
The tape is designed for use where an airtight and vapour-resistant membrane installation is required.
Correct sealing of membrane overlaps is important because unsealed joints can interrupt the continuity of the AVCL, VCL, DPM or gas barrier.
Particular attention should also be given to:
The complete installation should follow the technical requirements of the membrane being installed.
Novia Double Sided Butyl Tape is used to support the effective installation of compatible Novia Vapour Control Layers and Air and Vapour Control Layers.
The tape forms the seal within the membrane overlap, helping maintain continuity of the air and vapour control layer.
The final lap should then be completed using the appropriate compatible Novia sealing tape.
Novia Double Sided Butyl Tape can also form part of the specified sealing system for compatible Novia gas barrier membranes.
Gas barrier installations require particular care because continuity must be maintained across joints, penetrations and perimeter details.
The correct final sealing tape should therefore be selected according to the specific gas membrane installation instructions.
The tape is also suitable for jointing compatible Damp Proof Membranes.
It provides a double-sided seal within membrane overlaps while the appropriate final sealing tape completes the joint.
Mechanical fixing requirements and other installation details should follow the relevant membrane specification.
Novia Double Sided Butyl Tape can be used in conjunction with Novia Metallised BOPP Tape.
Within this arrangement:
This arrangement is used with compatible Novia membranes where Metallised BOPP Tape is specified.
For membrane systems requiring Novia Aluminium Foil Tape, the Double Sided Butyl Tape provides the seal within the overlap and the Aluminium Foil Tape provides the additional final seal.
The correct single-sided tape depends on the membrane being installed, so the relevant Novia technical guidance should be followed.
Novia Double Sided Butyl Tape forms part of the specified taped sealing system for Novia Methane Pro.
For the supplied Methane Pro installation specification, the Butyl Tape is used within the overlap and Novia Metallised BOPP Tape provides the final seal across the joint.
Maintaining a continuous gas seal is essential, so the complete Methane Pro installation should follow its dedicated technical datasheet and project gas protection specification.
Novia Double Sided Butyl Tape provides very good adhesion properties and is suitable for use on most surfaces within its intended membrane applications.
Surfaces should be appropriately prepared before application to achieve the required bond.
Installation should follow the relevant Novia membrane and tape guidance.
Novia Double Sided Butyl Tape is a jointing and sealing product, not a structural or load-bearing fixing.
It must not be used as the load-bearing element within a membrane installation.
Novia states that Air and Vapour Control Layers and Damp Proof Membranes also require mechanical fixings.
The appropriate mechanical fixing method should be determined by the membrane system and construction detail.
The 50mm wide version measures:
This provides 10 linear metres of double-sided butyl tape for compatible membrane jointing and sealing applications.
The wider version measures:
This provides the same 10m roll length with a wider sealing surface for applications requiring the 100mm format.
Two widths are available:
| Size | Roll Length | Thickness |
|---|---|---|
| 50mm | 10m | 1.5mm |
| 100mm | 10m | 1.5mm |
The correct width should be selected according to the membrane being installed and the requirements of the relevant Novia technical guidance.

Novia Double Sided Butyl Tape is a high-performance membrane jointing and sealing tape designed for compatible AVCL, VCL, DPM and gas barrier installations.
Novia Double Sided Butyl Tape is available in:
Both widths are supplied in 10m rolls.
The supplied specification states a thickness of 1.5mm.
It is used to seal membrane joints and overlaps against air and water vapour ingress within compatible Novia membrane installations.
Yes. Novia Double Sided Butyl Tape is designed for use with compatible Vapour Control Layers and Air and Vapour Control Layers.
Yes. It is suitable for jointing and sealing compatible Damp Proof Membranes.
Yes. Novia specifies Double Sided Butyl Tape for the effective installation of compatible gas barrier membranes.
Yes. Double Sided Butyl Tape forms part of the specified taped jointing system for Novia Methane Pro, with Metallised BOPP Tape used as the final seal.
It is normally positioned between the overlapping membrane sheets, creating a seal within the membrane lap.
Yes. Novia states that installations should be completed using either Novia Metallised BOPP Tape or Aluminium Foil Tape, depending on the membrane system, as an additional secure final seal.
The products perform different roles.
Double Sided Butyl Tape is installed between overlapping membrane sheets to create the primary joint seal.
Metallised BOPP Tape is applied across the completed overlap as the final external seal where specified.
Novia states that either Metallised BOPP Tape or Aluminium Foil Tape can be used as an additional secure seal, but the correct product depends on the membrane system.
For example, specific membranes may require a particular final sealing tape, so the relevant Novia installation instructions should be followed.
Novia Double Sided Butyl Tape is designed for use as part of an airtight and vapour-resistant membrane installation.
A complete airtight installation also depends on correct sealing of all overlaps, edges, penetrations, junctions and other details.
No. The tape is not suitable for use as the load-bearing element of a system.
Novia states that AVCL and DPM installations also require appropriate mechanical fixings.
Novia states that the tape provides very good adhesion properties and can be used on most surfaces within its intended applications.
Each roll provides 10 linear metres of tape.
As a simple guide:
Additional allowance should be made for detailing, cutting and installation wastage.
Novia Double Sided Butyl Tape is a high-performance jointing and sealing tape for compatible Vapour Control Layers, AVCLs, Damp Proof Membranes and Gas Barriers.
Providing very good adhesion, the tape is positioned within membrane overlaps to help create an airtight and vapour-resistant seal. The installation should then be completed with the appropriate Novia Metallised BOPP Tape or Aluminium Foil Tape as the final secure seal.
Available in 50mm x 10m x 1.5mm and 100mm x 10m x 1.5mm rolls, Novia Double Sided Butyl Tape provides a dedicated sealing solution for compatible Novia membrane systems.
The tape is intended for jointing and sealing only and must not be relied upon as a load-bearing fixing.
