Novia Mirrorwrap W1 is a premium, high-performance wall breather membrane designed for use in high-specification timber frame and insulated wall applications. This 4-layer laminate combines exceptional thermal enhancement with robust weather protection, ensuring your building envelope remains energy-efficient and dry.
As a single-sided reflective foil, Mirrorwrap W1 is a premium solution for those looking to boost the energy rating of a structure. When correctly installed facing into an unventilated wall cavity, it is possible to achieve an additional R-value of up to 0.74 m²K/W. This helps reduce the thickness of bulk insulation required while significantly improving thermal performance.
Key Features
- Superior Reflectivity: Features a reflective face with a reflectivity of 98%, allowing the building to maintain high thermal resistance during both summer and warmer periods.
- Class W1 Water Resistance: Meets EN 1928 Class W1 for water penetration, providing a class W1 water resistant barrier against driving rain and wind-blown snow.
- High Breathability: Despite its thermal properties, it acts as a high-performance breathable membrane, allowing vapour to escape from the internal structure to prevent interstitial condensation.
- Standardised Compliance: The product is CE certified and UKCA marked; it complies with EN 13859-2 for wall applications.
- Optimal Roll Size: Available in a generous 2.7m x 100m format, making it easier to cover large areas with a single sided overlap, improving airtightness.
Applications
Novia Mirrorwrap W1 reflective wall membrane is specifically ideal for use on timber frame constructions and any wall breather membrane for insulated systems.
- Timber Frame Construction: Acts as the primary reflective wall breather on the cold side of the insulation, protected by the cladding or masonry outer leaf.
- Insulated Wall Applications: Specifically designed for use where an additional R-value is required to meet Part L building regulations.
- Airtightness Layers: Used in conjunction with a Novia vapour control layer (VCL) on the warm side of the insulation to create a fully managed building envelope.
