Concrete masonry units are up to 40% lighter than traditional units when produced using Utelite Expanded Shale Aggregates. This lighter weight results in increased mason productivity, lower construction costs and reduced injuries. Concrete masonry units produced with Utelite Expanded Shale Aggregates also provide superior insulation by combining high R-values with thermal mass and low thermal bridging. In addition, lightweight masonry units offer superior fire resistance, effective sound absorption, excellent seismic performance, low shrinkage and high strain capacity.
