Insulated CMU

Effectively Controls Sound

Pre-insulated concrete masonry units (CMUs) improve thermal efficiency of building envelopes. The units offer designers several energy efficiency solutions for projects where a higher R-value is desired or required. CMUs come in many colors, shapes and sizes to bring out the unique style of your construction project.

We offer two types of insulated units, depending on your specific needs. All units are available in all of our colors and finishes, and they come in a variety of sizes.

Hi-R® Insulated Block

Hi-R® is a specially-designed CMU with smaller webs to reduce thermal bridging and contains individually molded insulation inserts, which do not hinder the structural integrity of masonry construction. This unit achieves higher R-values than standard CMU insulation.

Standard CMU with Korfil® Inserts

Our pre-insulated masonry units feature Korfil® inserts and offer performance that delivers R-Values up to R-11, depending on block density. Korfil® inserts are a cost-effective way to insulate standard CMUs. Inserts are pre-installed in the unit before they arrive at your jobsite.

What we’re proud of

Product Highlights

Superior Thermal Performance: Pre-insulated CMUs with Hi-R® technology or Korfil® inserts deliver exceptional R-values up to R-11, significantly improving building envelope efficiency.

Structural & Protective Benefits: Combines structural strength with inherent fire and moisture resistance while reducing energy consumption through effective temperature regulation.

Design Versatility: Available in numerous colors, shapes, and sizes with specialty options for corners, lintels, and bond beams—perfect for schools, offices, and municipal projects.

Features of Insulated CMU

Insulated CMU walls are structurally strong, as well as inherently fire- and moisture-resistant. The hollow cores of insulated CMU blocks are filled with insulating materials to keep heat inside during the winter and keep heat outside during the summer. This leads to reduced energy consumption within your building structure.

We provide special non-insulated shapes for functional and aesthetic purposes. These include corners, lintels, sashes, jambs and bond beams.

Uses for Insulated CMU

Insulating CMU block walls are great for exterior and interior walls. The units’ long-lasting durability allows them to function as load-bearing walls for basements or foundations.

Select insulated CMU blocks for your next school, office or municipal construction project. You can view York Building Products’ extensive gallery of sample work to check out previous projects that have been completed with our CMUs.
