Exterior wood framing walls must be constructed from a minimum grade of wood that ensures durability and structural integrity while resisting the elements. Grade 3 wood is typically the lowest acceptable grade used in construction, particularly for framing applications. This grade provides sufficient strength and stability for typical residential building needs. Using Grade 3 wood allows contractors to ensure that the walls will withstand normal stresses, provide adequate insulation, and support the overall structure without excessive warping or defects.

The lower grades, such as Grade 1 and Grade 2, are reserved for applications where higher strength and aesthetic qualities are not as critical, while Grade 4 wood would typically be deemed unsuitable for structural framing due to its lower quality and strength characteristics. Therefore, opting for Grade 3 helps maintain a balance between cost and functional performance for residential construction projects.
