Novia Reflex is a high-quality reflective breather membrane designed for pitched cold roofs, pitched warm roofs and insulated wall applications. Its 4-layer metallised polypropylene and microporous film construction combines excellent water resistance and high breathability with a low-emissivity reflective surface that can contribute to improved thermal performance when incorporated into a suitable construction.
Suitable for both roof and wall applications, Novia Reflex is CE compliant to EN 13859-1 for roofs and EN 13859-2 for walls, CPR compliant and achieves Class E to EN 13501-1.
The membrane has also been tested for BS 5534 wind uplift applications. Novia Reflex can be used in UK wind zones 1 and 2 without additional tapes and in zones 1 to 5 when installed with the specified Novia Breather Membrane Lap Tape system.
Supplied as a 1.5m x 50m roll, each roll provides 75m² nominal coverage.
Key benefits include:
Novia Reflex is a versatile reflective breather membrane suitable for applications including:
Its combination of breathability, water resistance and reflective performance allows one membrane to be used across a variety of roof and wall construction details.
Unlike a standard non-reflective breather membrane, Novia Reflex incorporates a low-emissivity reflective surface.
When installed as part of a suitable construction, the reflective surface can contribute to improved thermal performance.
Novia states that the membrane can deliver improved R and μ values, with example calculations produced for Novia by the BRE.
The actual thermal benefit depends on the complete construction, including the position of the membrane, adjacent cavities and other materials within the building element.
Novia Reflex should therefore not be treated as a replacement for the primary insulation within a roof or wall.
Novia Reflex uses a 4-layer metallised polypropylene and microporous film laminate.
This construction combines:
The result is a single reflective breather membrane suitable for both appropriate roof and wall applications.
Novia Reflex provides high breathability, allowing water vapour to pass through the membrane as part of an appropriately designed roof or wall construction.
Novia describes Reflex as providing much higher breathability than many other reflective breather products.
This makes it particularly useful where both reflective characteristics and vapour permeability are required.
Novia Reflex provides excellent water resistance while maintaining high breathability.
This combination allows the membrane to perform as an external breather membrane within appropriate pitched roof and insulated wall constructions.
Installation, overlaps, penetrations and detailing should follow the relevant Novia technical guidance.
Novia Reflex is suitable for both:
It is CE compliant to:
EN 13859-1 for roof applications
Its reflective surface can also provide additional thermal benefits when incorporated into an appropriate roof construction.
Novia Reflex is also suitable for insulated wall applications.
For wall applications, the product is CE compliant to:
EN 13859-2
This allows Reflex to provide a single reflective breather membrane solution across compatible roof and wall construction details.
Novia Reflex has been successfully tested for use in BS 5534 wind uplift applications.
According to the supplied Novia specification:
UK Wind Zones 1 and 2
Novia Reflex can be used without additional tapes.
UK Wind Zones 1 to 5
Novia Reflex can be used with the specified Novia Breather Membrane Lap Tape system.
This allows the membrane to be used across all UK wind zones when the appropriate taping arrangement is installed.
The relevant Novia wind zone map and product installation guidance should be checked before installation.
Where taping is required for the applicable BS 5534 wind zone, Novia Reflex should be installed using the appropriate Novia Breather Membrane Lap Tape system.
This can include:
The double-sided tape is positioned within the membrane overlap, while the single-sided tape provides the final seal across the lap where the complete two-tape system is specified.
The exact taping requirement should be determined from the relevant Novia technical information and UK wind zone.
Novia Reflex is fully CE approved for its specified roof and wall applications and is CPR compliant.
The applicable standards are:
These standards relate to flexible sheets used as underlays within roof and wall construction.
Novia Reflex achieves:
EN 13501-1 Class E
This is the stated reaction-to-fire classification for the membrane.
Where a higher fire classification is required, Novia recommends selecting an appropriate higher fire-rated breather membrane from its range.
The suitability of the membrane should always be considered as part of the fire requirements for the complete construction.
Novia Reflex is designed to provide a combination of strength and lightweight handling.
This makes the membrane practical to transport, position and install across roof and wall applications while maintaining the required membrane performance.
The low-emissivity surface of Novia Reflex can contribute to improved thermal performance when installed in an appropriate construction.
The benefit depends on factors including:
Any project-specific U-value or R-value calculation should therefore be based on the complete construction rather than the membrane alone.
The versatility of Novia Reflex allows a single membrane to be considered across several building applications.
Roof applications include:
Wall applications include:
The complete construction should follow the relevant project and Novia technical requirements.
Each roll measures:
1.5m wide x 50m long
Providing:
75m² nominal coverage
Actual usable coverage may be lower after allowing for membrane overlaps, cutting and installation wastage.
