The ADEX-CB (cement board) system is a dual-barrier, rainscreen cladding assembly incorporating an impact resistant, lightweight cement board sheathing. The system is coated with an EIFS lamina consisting of; an acrylic basecoat, glass-fibre reinforced mesh, primer and a 100% acrylic finish coat.


  • The system is designed around the rainscreen “cavity wall” principle that moves the finish system away from the substrate to create a drainage plane and air space to help manage moisture.
  • Insulation can also be used (between the furrings) to increase the total R-value of the assembly.
  • This system provides excellent impact resistance.


  • Seamless substrate protection.
  • Rainscreen assembly with vented drainage cavity.
  • Non-combustible basecoat.
  • Unlimited colour selection.
  • Durable cement board.


  • Seals the building envelope and ensures seamless protection of the substrate.
  • Allows for the drainage and quick drying of incidental moisture.
  • Architectural design flexibility.
  • Cement board core resists damage from impact and moisture.
