Fire-Rated Vapour Control Layer

IZOPERM PLUS A2 is a limited combustible vapour control layer with an A2-s1,d0 Reaction To Fire classification. This high-performance membrane is designed to protect building elements from degradation by restricting the movement of water vapour from inside the building to within the building structure, thus helping to prevent interstitial condensation. Additionally, it enhances the building fabric in terms of airtightness and energy efficiency, while also providing a high standard of fire performance.

Why Partel IZOPERM™ PLUS A2?

  • Reaction to fire classification A2-s1,d0, tested with Partel ECHOSEAL ALU FR adhesive tape to BS EN 13501-1
  • Fire rated and suitable for high rise constructions as per current Building Regulations
  • Vapour closed with an Sd value of 2000 m
  • Vapour resistance 10000 MNs/g
  • Airtight with an air permeability value of <0.01 m³/m²·h@50 Pa
  • Class W1 resistance to water penetration, to EN1928
  • Reflective material with a low emissivity of ≤ 0.05, improves thermal performance by reflecting up to 95% of a building’s interior heat loss
  • Its composite nature, based on lacquered aluminium, results in a stronger vapour control layer, providing superior structural stability for buildings
  • UKCA & CE compliant to EN 13984
