The ADEX-XNC system is a non-combustible variation of exterior insulation and finish systems (EIFS) that incorporates the use of a rigid rock-based mineral fiber insulation. The ADEX-XNC system is specified where there are limiting distance issues or the where the exposed building face allows less than 10% unprotected openings.
The ADEX-XNC system incorporates a secondary liquid applied weather resistive barrier (LA-WRB) and a vertical drainage plane to assist with moisture management.


  • Mineral Fibre Insulation is non-combustible.
  • Uniform blanket of continuous insulation (CI); reduces energy use.
  • Basecoat and Insulation components meet CAN/ULC-S114: Method of Test for Determination of Non-Combustibility in Building Materials.
  • The liquid applied weather resistive barrier (LA-WRB) provides seamless protection of the building envelope against air and moisture infiltration.


  • Continuous insulation (CI).
  • Seamless substrate protection.
  • Non-combustible basecoat.
  • Non-combustible mineral fibre insulation.
  • Unlimited colour selection.


  • Continuous insulation; reduces energy use.
  • Seals the building envelope and ensures seamless protection of the substrate.
  • Allows for the drainage of incidental moisture.
  • Durable and flexible.
  • Architectural design flexibility.
  • Non-combustible materials.
