Which aspect is NOT typically a benefit of using CMUs?

Using Concrete Masonry Units (CMUs) provides several benefits, making them a popular choice in construction. Among these are energy efficiency, ease of installation, and fire resistance.

Energy efficiency is one of the significant advantages of CMUs because they have good thermal mass properties, which help to stabilize indoor temperatures, reducing the need for heating and cooling.

Ease of installation is another key benefit. CMUs are relatively easy to handle and can be quickly laid, making the construction process more efficient and allowing for faster project completion times.

Fire resistance is a notable characteristic of CMUs. These blocks are non-combustible, which enhances the safety of structures by reducing the risk of fire spreading.

The aspect that is not typically a benefit is high cost. While CMUs can have a higher initial cost compared to some other materials, they often provide long-term savings due to their durability, low maintenance requirements, and energy efficiency. Therefore, the overall value they offer tends to offset any high upfront costs.
