CMU and ICF wall systems also aim for suburb indoor environmental quality (IEQ). The mass of the wall system stores energy during the day and releases it throughout the night, which makes mass walls, like CMU and ICF, an excellent choice in hot and humid conditions.Both CMU and ICF wall systems strive to create durable structures that are resistant to wind, moisture, fire, rot, and mold. Mass walls provide energy efficiency through mass, rather than insulative values. However, ICF is quicker and easier to install compared to CMU, which saves time and money.CMU and ICF are mass wall systems used in energy-efficient commercial and residential construction. Concrete masonry units (CMU) and insulated concrete form (ICF) walls have several features in common: energy-efficiency, durability, and good indoor environmental quality (IEQ).
