Application

EXOPERM MONO DURO A2 is an external breather membrane of limited combustibility designed for use on the cold side of insulation of façade wall applications, offering the highest standard of fire-safety and protection for tall buildings.


Suitable for:

  • Façades with open or closed joints.
  • High-rise, high-risk and public buildings (schools, offices, commercial centres, hospitals, etc.).
  • Residential and commercial developments.
  • Offsite construction.
  • Metal frame constructions.
  • New builds and retrofits.

Description

EXOPERM MONO DURO A2 is a limited combustible, energy-efficient, diffusion permeable monolithic breather membrane. Class A2-s1,d0 it provides high fire protection of the building envelope and is ideal for installation on the façade, in high-rise and high-risk buildings. 


Features and benefits:

  • Reaction to fire A2-s1,d0 to BS EN 13501-1.
  • Advanced glass fibre fabric for enhanced structural stability.
  • Integrates Monolithic functional layer.
  • Highly vapour open with an Sd value of 0.09m.
  • Class W2 resistance to water penetration.
  • Airtight with an air permeability value of 0,006 m³/m², h, Pa.
  • High Permanent UV resistance without cladding, and with 50% and 50mm joints.
  • Weather tight.
  • Improves the energy efficiency of the building.
  • Independently tested to EN 13501-1 for compliance.
