    Solutions for Non-combustible Construction

    Creating non-combustible exterior wall assemblies has become increasingly challenging as building design has evolved toward greater levels of energy efficiency. To meet the requirements of the International Energy Conservation Code, buildings have incorporated air/water-resistive barriers on exterior sheathing and CMU walls, together with extensive use of exterior insulation. In addition to improving energy efficiency, these changes can provide effective moisture management by incorporating an airtight secondary drainage plane, and by moving the dew point of the wall assembly outside of the drainage plane. 

    However, both the air/water-resistive barrier and many types of exterior insulation are made from organic materials that are combustible. One challenge for design professionals is to incorporate combustible materials into noncombustible construction in a way that reliably provides the fire performance required by the International Building Code. Finestone Pebbletex CI-DCA, Pebbletex CI-DCA with MaxGrip Veneer Mortar, Pebbletex Platinum CI and Platinum CI Stucco Ultra Wall Systems have been comprehensively qualified for use in noncombustible construction. When installed per Finestone details and instructions, they provide codecompliant fire performance as listed on system brochures. This extensive set of ​​performance data is steadily updated as local and national fire standards evolve.​

    Finestone CI Wall Systems incorporate a Finestop air/water-resistive barrier, continuous exterior insulation and an outer skin that can be finished to create a broad range of appearances. These systems meet the full range of International Building Code and International Energy Conservation Code requirements, and are supported with third-party test data, architectural details and system warranties. Utilizing Finestone CI Wall Systems provides a simplified approach to wall cladding design.​
