SuperFOIL SFTV FR Aluminium Foil Membrane – 1m x 25m

SuperFOIL SFTV FR Aluminium Foil Membrane is a high-performance reflective vapour control layer (VCL) and radiant barrier designed for use in insulated roofs, walls and floors.

Manufactured with a strong woven pure aluminium construction, SFTV FR combines excellent vapour resistance, waterproofing and durability with a highly reflective surface that helps reduce radiant heat loss. Installed on the warm side of the insulation, it helps prevent warm, moisture-laden air from entering the insulated construction, reducing the risk of condensation, damp, mould and rot.

The reflective aluminium surface also acts as a radiant barrier, returning radiant heat towards the living space and helping improve the overall thermal performance of the building envelope when installed adjacent to a suitable airspace.

SuperFOIL SFTV FR is W1 waterproof, provides an exceptionally high water vapour resistance of 538 Sd / 2690 MNs/g, and achieves Euroclass E reaction to fire performance.

Supplied in a 1m x 25m roll, each roll provides 25m² of coverage, making this smaller roll particularly practical for extensions, renovations and smaller areas.

What is SuperFOIL SFTV FR Used For?

SuperFOIL SFTV FR is a versatile reflective vapour control membrane suitable for use in:

• Insulated walls
• Pitched and suitable roof constructions
• Insulated floors
• Timber frame construction
• Dry lining applications
• New-build properties
• Extensions
• Refurbishment and retrofit projects
• Energy-efficiency upgrades
• Condensation control applications
• Airtightness and vapour control systems

It is particularly suited to installation as a dry lining membrane directly behind the internal finishing layer, such as plasterboard.

High-Performance Vapour Control Layer

SFTV FR provides an exceptionally effective vapour control layer, helping restrict the movement of warm, moisture-laden air from the occupied space into insulated walls, roofs and floors.

The membrane provides a water vapour resistance of 538 Sd / 2690 MNs/g, creating a highly vapour-resistant layer on the warm side of the insulation.

Effective vapour control helps reduce the amount of moisture entering colder parts of the building construction, reducing the risk of interstitial condensation and associated long-term problems.

Helps Reduce Condensation, Damp and Mould

Warm air generated inside a building contains water vapour. As this air moves towards colder areas of the building envelope, the water vapour can condense within the construction.

Over time, excessive moisture can contribute to:

• Interstitial condensation
• Dampness
• Mould growth
• Timber decay and rot
• Reduced insulation performance
• Deterioration of building materials

SuperFOIL SFTV FR helps control this moisture movement by creating a highly vapour-resistant layer between the occupied space and insulation.

Reflective Radiant Barrier

In addition to vapour control, SuperFOIL SFTV FR features a highly reflective aluminium surface that acts as a radiant barrier.

Its ultra-low emittance surface helps reduce radiant heat transfer through the building envelope, reflecting radiant energy back towards the internal living space.

When correctly installed adjacent to an appropriate airspace, this reflective performance can provide additional thermal resistance and contribute towards improved overall U-values and building energy efficiency.

Thermal Performance

SuperFOIL SFTV FR can provide additional thermal resistance when correctly installed as part of a suitable roof, wall or floor construction.

The stated thermal resistance values are:

• Roof application: 0.4898 m²K/W R-value
• Wall application: 0.7398 m²K/W R-value
• Floor application: 1.622 m²K/W R-value

Actual thermal performance will depend on the complete construction, orientation, adjacent airspace and installation method.

This additional thermal resistance allows SFTV FR to perform as more than a conventional vapour control layer, combining vapour management with radiant barrier performance.

W1 Waterproof Membrane

SuperFOIL SFTV FR is certified to W1 water resistance, providing a high level of resistance to water penetration.

Its waterproof and highly vapour-resistant construction helps provide an effective protective layer within suitable insulated building systems.

This combination of water resistance and vapour control makes SFTV FR suitable for demanding roof, wall and floor applications where moisture management is an important part of the overall building design.

Strong Woven Aluminium Construction

SFTV FR features a woven pure aluminium construction designed to provide excellent tensile properties and improved resistance to tearing.

The reinforced woven structure provides additional strength during handling and installation, helping reduce the risk of accidental damage when positioning and fixing the membrane.

This makes it particularly suitable for professional construction, refurbishment and retrofit applications where durability is important.

Suitable for Walls, Roofs and Floors

SuperFOIL SFTV FR is designed as a multi-purpose membrane that can be incorporated into a wide variety of insulated building elements.

It can be used within suitable:

• Wall constructions
• Roof constructions
• Floor constructions

This versatility makes SFTV FR suitable for both new-build and existing properties, including extensions, renovations and energy-efficiency upgrades.

Ideal for Dry Lining Applications

SuperFOIL SFTV FR is particularly suited to use as a dry lining membrane installed directly behind plasterboard or another suitable internal finishing layer.

Positioning the membrane on the warm side of the insulation allows it to control the movement of water vapour before moisture reaches colder parts of the insulated construction.

Careful sealing of joints, edges and penetrations is important to create a continuous vapour control and airtightness layer.

Convenient 25m² Roll

This version of SuperFOIL SFTV FR is supplied in a compact 1m x 25m roll, providing 25m² of coverage.

The shorter roll is particularly convenient for:

• Smaller extensions
• Individual rooms
• Partial roof areas
• Wall upgrades
• Floor insulation projects
• Repairs and refurbishment
• Projects where a full 50m roll would create unnecessary surplus material

The 1m width also provides a practical size for handling and positioning during installation.
