Disadvantages of using glass as building material?

Using glass as a building material presents several disadvantages, including its vulnerability to breakage and the potential for safety hazards. It typically has lower insulation properties compared to other materials, leading to increased energy consumption for heating and cooling. Additionally, glass can be costly and may require special coatings or treatments to enhance durability and reduce glare, which can further increase construction expenses. Lastly, privacy concerns can arise in buildings with extensive glass facades.
