What is an advantage of using a two-core masonry block?

Explanation:
Two-core masonry blocks are designed with hollow cores that cut weight while the webs between those cores provide needed strength. Those two cores create space inside the wall to run electrical conduits and plumbing, making installation easier and faster without adding bulk to the wall. The webs are kept thick enough to maintain structural integrity even with the hollows, so you gain lighter weight plus practical service cavities. In contrast, higher thermal conductivity isn’t desirable for walls, more mortar absorption can cause moisture and finishing issues, and thinner webs would reduce the block’s strength.
