Open Cell Insulating Units

 Open Cell Single Core units installed with insulating core materials enhance R-values and result in better energy performance for CMU cavity wall construction. Open Cell units are manufactured with 3/4” webs that improve R-Values, increase occupant comfort levels, and lower energy and equipment costs over the life cycle of the building.

Open Cell units are NCMA & ASHRAE Approved Series Parallel (Isothermal Planes) R-Values.


  • Reduced web thickness to 3/4”
  • Improved R-Value
  • Units pass energy code requirements
  • Lower weight (see chart above) increases efficiency for masons and reduces injury potential
  • Meets ASTM C90 requirement
