About EnduraMax® High Performance Wall System

Every component of the EnduraMax® High-Performance Wall System is specifically engineered to work together, forming an energy efficient concrete block that is the ideal building material and cladding solution. The complete stone veneer wall system offers an insulation value of R9.2 steady state. This extra layer of thermal protection means building owners can benefit from a cladding system that helps meet and exceed today’s demanding energy codes. This product is certified by the Florida Department of Business & Professional Regulation, #FL 27462.

Technical Data

Meeting a Higher Standard

EnduraMax’s continuous insulation barrier is an ideal way to meet Energy Star’s strict energy performance score requirements. The superior thermal performance of this building material will contribute to eligibility for a Designed to Earn the Energy Star (DEES) certification. With the help of the EnduraMax Wall, you can truly distinguish a building by being able to meet this prestigious standard for energy efficiency.

  • Moisture Management
    As a total cladding solution, the EnduraMax System integrates all components necessary to achieve superior moisture management (based on independent tests). Channels in the front and back drain any water that may infiltrate the wall, protecting the structure from damage over a long lifetime of moisture exposure.
  • Sound Proofing
    The foam panels have an STC rating of 51 (based on independent tests) – meaning even extremely loud sounds such as a stereo, lawn mower or traffic are only faintly heard. This enhanced acoustical comfort means occupants can enjoy their space in peace
  • Wind Rating
    The EnduraMax stone veneer wall is tough enough to withstand the harshest environments. It’s been proven to resist wind speeds of more than 110 mph (ASTM E330) with no lasting deformation. The heavy EnduraMax system essentially eliminates the risk of costly damage experienced with lighter-weight veneers
  • Fire Resistance
    EnduraMax meets NFPA 285 and ASTM E119 fire resistance criteria. Tested walls successfully withstood one hour of exposure to temperatures of more than 1,700°F.


Cross-Section of the Specially Designed EnduraMax Anchor System

EnduraMax™ Wall System consists of three essential elements that combine to deliver unmatched performance & beauty to your project.

  1. Foam Installation Panels
    • Polystyrene insulation panels include premolded cells on the outside face, which form the pattern for installing masonry units.
    • Drainage channels in the front and back of each panel allow any water that infiltrates the wall to escape.
  2. Masonry Units
    • Masonry units insert easily into cells of the foam panels for quick installation
    • Stone, clay and concrete brick options offer unique aesthetically pleasing designs.
  3. EnduraMax Mortar
    • A pre-blended, proprietary mortar that complies with  ASTM C270 enhances pumpability, bond strength,  flexibility and dimensional stability.


EnduraMax Wall Detail in 2x4 and 2x6 Construction

As codes continue to move toward tougher building envelope standards, the superior thermal performance of EnduraMax concrete blocks enables you to exceed increasingly stringent R-Value requirements without having to add additional exterior insulation or build larger wall cavities.

EnduraMax may be installed on metal frame or wood frame buildings up to climate zone 6. Zones 7 and 8 may also be addressed by evaluating the building characteristics and installation details.
