Novia MirrorWrap W1 is a high-quality, 4-layer reflective wall breather membrane designed for insulated wall applications, timber frame construction and off-site or modular building systems. Combining Class W1 water resistance with high vapour permeability and 98% reflectivity, MirrorWrap W1 can contribute to improved thermal performance when correctly installed adjacent to a suitable cavity.
Supplied as a large 2.7m x 100m roll, each roll provides 270m² nominal coverage, making it particularly suitable for larger timber frame, modular and professional construction projects.
Key benefits include:
Novia MirrorWrap W1 is designed as a reflective breather membrane for insulated wall constructions.
Typical applications include:
The membrane combines weather resistance, breathability and a highly reflective surface within a single 4-layer product.
One of the principal features of Novia MirrorWrap W1 is its 98% reflective surface.
When correctly installed adjacent to an appropriate unventilated wall cavity, the reflective surface can reduce radiant heat transfer and contribute towards improved thermal performance.
It is possible to achieve an additional R-value of up to 0.74m²K/W when correctly installed within a suitable unventilated wall cavity.
This can help improve the overall U-value of the wall construction.
Actual thermal performance will depend on the complete wall build-up, cavity arrangement and installation.
MirrorWrap W1 is designed to contribute to the thermal efficiency of insulated wall constructions.
The reflective face helps manage radiant heat transfer, contributing towards a construction that can remain cooler during summer and warmer during winter.
This makes the membrane particularly useful for projects where improving the thermal performance of the overall wall build-up is a priority.
Novia MirrorWrap W1 achieves Class W1 water resistance to EN 1928.
W1 is the highest water resistance classification used for this type of breather membrane, providing protection against external moisture when incorporated correctly into a suitable wall construction.
At the same time, MirrorWrap W1 remains highly vapour permeable, allowing water vapour to pass through the membrane as part of an appropriately designed wall system.
Despite its high level of water resistance, MirrorWrap W1 provides high vapour permeability.
This combination allows the membrane to resist external water while supporting the controlled movement of water vapour through the wall construction.
This is particularly important within insulated timber frame and other framed wall systems where moisture management forms an important part of the overall construction design.
Novia MirrorWrap W1 is described as airtight and highly vapour permeable, providing a useful combination of properties for modern insulated wall construction.
Correct installation, including appropriate treatment of laps, joints, penetrations and interfaces, is important to achieve the intended performance of the membrane within the completed wall system.
MirrorWrap W1 is particularly suited to timber frame construction, where breather membranes are commonly incorporated on the external side of the insulated frame.
Its combination of:
makes it a practical choice for modern timber frame wall systems.
Novia MirrorWrap W1 is also ideal for off-site and modular construction.
The substantial 2.7m width can be particularly useful for larger wall sections, helping reduce the number of separate membrane runs required compared with narrower roll formats.
This makes the 2.7m x 100m roll well suited to professional and large-scale construction environments.
MirrorWrap W1 uses a 4-layer laminate construction with a microporous core.
This construction provides the combination of water resistance and high vapour permeability required from a modern wall breather membrane, while incorporating the reflective surface required to improve thermal performance when installed correctly.
To maximise reflective performance, the reflective face of Novia MirrorWrap W1 is deliberately supplied without Novia branding, text or printed images.
The reverse side of the membrane is white.
The unprinted reflective surface helps maximise the area available to provide the membrane’s stated 98% reflectivity.
Each roll measures:
2.7m wide x 100m long
Providing a nominal area of:
2.7m x 100m = 270m²
Actual usable coverage will be lower once appropriate laps, joints, detailing, penetrations, cutting and general wastage are taken into account.
The large 2.7m width is particularly suited to substantial wall areas, timber frame construction and modular building applications where reducing the number of individual membrane runs can be beneficial.
Novia MirrorWrap W1 provides specified performance against recognised standards for wall breather membranes.

Novia MirrorWrap W1 is a 4-layer reflective wall breather membrane designed for insulated wall applications.
It combines Class W1 water resistance, high vapour permeability, airtightness and 98% reflectivity.
This roll measures 2.7m wide x 100m long.
A 2.7m x 100m roll provides 270m² nominal coverage.
Actual usable coverage will be lower after allowing for laps, detailing, cutting and wastage.
Yes. MirrorWrap W1 is a highly vapour permeable wall breather membrane designed for insulated wall applications.
MirrorWrap W1 achieves Class W1 water resistance to EN 1928.
It is more accurate to describe the product according to this tested water resistance classification rather than simply referring to it as waterproof.
MirrorWrap W1 has a stated 98% reflectivity.
Yes. The highly reflective surface can contribute towards improved U-values by reducing radiant heat transfer when incorporated correctly into an appropriate wall construction.
When correctly installed adjacent to a suitable unventilated wall cavity, MirrorWrap W1 can achieve an additional R-value of up to 0.74m²K/W.
Actual performance depends on the complete construction and installation.
The stated additional R-value is achieved when the reflective membrane is correctly installed in conjunction with an appropriate unventilated wall cavity.
The complete construction should therefore be designed and installed according to the relevant project specification and manufacturer guidance.
Yes. MirrorWrap W1 is specifically suitable for timber frame wall applications.
Yes. Novia identifies MirrorWrap W1 as ideal for off-site and modular construction, as well as conventional timber frame applications.
Yes. MirrorWrap W1 is specified as airtight and highly vapour permeable.
