How should intermittent shims be spaced according to standard practice?

• A. 6 to 12 inches
• B. 12 to 18 inches
• C. 18 to 24 inches
• D. 24 to 30 inches

Answer: (C)

Intermittent shims play a crucial role in ensuring that the glazing system is correctly aligned and adequately supported. Spacing these shims at 18 to 24 inches is standard practice because it provides a balance between structural integrity and flexibility. This spacing allows for sufficient load distribution, which helps manage the stresses and strains on the glazing system while facilitating proper installation. When shims are spaced at this interval, they effectively support the weight of the glazing units and accommodate any thermal expansion or contraction that may occur. This range also minimizes the risk of sagging or misalignment in the glazing system, which could lead to potential failure or performance issues over time. Proper shim spacing is vital for maintaining the durability and efficiency of the overall glazing installation, ensuring that it adheres to both safety and aesthetic standards.
