During wall covering installations, how many square feet of thin exterior structural glass veneer is allowed above 15 ft?

The correct answer indicates that a maximum of 5 square feet of thin exterior structural glass veneer is permissible above 15 feet during wall covering installations. This regulation is rooted in the need for safety and building integrity, as larger expanses of glass at significant heights can pose risks related to wind loads, thermal expansion, and impact resistance. Limiting the area of glass installation reduces these risks, ensuring that the materials used in construction meet safety standards and can withstand environmental factors effectively.

In practical terms, this limitation is important for inspectors to monitor, as it helps maintain the building's structural integrity and ensures compliance with local building codes and regulations. By specifying a conservative size for glass veneer, building codes prioritize user safety and the longevity of the structure.
