Insulated CMU

For projects where a higher R-value is desired or required, pre-insulated CMU offers designers several solutions for energy efficiency.


We offer two types of insulated units, depending upon your specific needs.

Hi-R® Insulated Block
Hi-R® is a specially-designed CMU with smaller webs to reduce thermal bridging, and contains individually molded insulation inserts. This unit achieves higher R-values than standard CMU insulation.

Standard CMU with PolyCore™ Inserts
Our pre-insulated masonry units feature PolyCore™ inserts, and offer performance that delivers R-Values up to R-11 depending on block density.


All units available in all of our colors and finishes.
