What is the minimum required air space clearance for wood girders supported on masonry or concrete walls?

1/4 inch
1/2 inch
1 inch
3/4 inch

The correct answer is: 1/2 inch

The minimum required air space clearance for wood girders supported on masonry or concrete walls is established to mitigate moisture-related issues that could compromise the integrity of the wood over time. An air space of 1/2 inch is specified in building codes to provide adequate ventilation and prevent direct contact between the wood and the masonry or concrete, which can be prone to dampness. This clearance helps reduce the risk of rot, decay, and insect infestation, ensuring that the structural components maintain their strength and durability throughout their lifespan. Establishing a proper air space is a crucial aspect of construction that contributes to the overall longevity and safety of the building structure.
