There’s a reason that high performance lightweight concrete masonry made with expanded shale clay or slate lightweight aggregate, appropriately named SmartWall, is widely used in schools, big box retail and other projects. In a sustainable environment, the quality and economy of lightweight cmu walls makes SmartWall the material of choice by building designers and mason contractors in many parts of the country today.
Minimum net compressive strength 2500 psi and maximum concrete density of 93 lbs per cubic foot.
Thermal mass, heat capacity, thermal bridges. R-values, ASHRAE energy code and the ENVSTD program
Heat flow, Series-parallel, Thermal resistance.
Commercially available Lightweight and Normalweight SRW, 13 suppliers, 33 concrete mixtures, 175 test samples.
Shows that SmartWall Systems provides significant savings in all climates.
Although unit price may be slightly higher, increased productivity more than offsets the expense when looking at costs in laying up a wall. Reprint Storypole, by Kyle Lochonic
