Novia® ReflexXLBreathableReflectiveWallMembrane

Suitable for use in all insulated frame applications.


High-quality reflective breather membrane that complies with EN 13859-1. When used in suitable construction (e.g. facing an airgap), this membrane will deliver improved R and U-Values (thermal resistance and thermal transmittance). Novia Reflex also complies with EN 13501-1 fire classification grade E.

Features and Benefits:

  • Tri-laminate membrane with low emissivity and high reflectivity.
  • Waterproofing properties to EN 1928 W1.
  • UV resistance: Install as per BS 5534:2014 + A2 2018 UV guidance.
  • High tensile and nail tear strength.
  • Cost effective.
  • Applied with a transparent coating that reduces the corrosion and avoids reflectivity loss over time.
  • Cooler in summer and warmer in winter.
  • Complies with European Construction Products Regulations (CPR) rules.
  • CE compliant to EN 13859-1.

Consult manufacturer's literature for installation guidelines.
