Why masonry hollow block is advantageous than solid block?

Masonry hollow blocks offer several advantages over solid blocks, primarily due to their lighter weight, which makes them easier to handle and reduces transportation costs. They also provide better insulation properties, contributing to energy efficiency by maintaining more consistent indoor temperatures. Additionally, the hollow cores can be filled with concrete or reinforced with steel, enhancing structural strength while still allowing for reduced material usage. This versatility makes hollow blocks a popular choice in construction.
