According to Timber Development UK, a single timber sole plate most often used in timber frame construction has a depth of 38mm.
Standard Sole Plate Dimensions
Based on common practice in timber frame construction, the standard or most frequently used size for a single timber sole plate is defined by its depth. The reference indicates this is typically 38mm.
This 38mm depth provides a solid base for the timber frame walls to rest upon, distributing loads evenly onto the foundation below.
Variations in Sole Plate Size and Configuration
While 38mm depth is the most common size for a single sole plate, it's important to note that other thicknesses and configurations can be used depending on specific structural requirements and design considerations.
Possible variations include:
- Different thicknesses: Sole plates may be thicker than the standard 38mm in certain applications.
- Double members: The reference mentions the possibility of using two sole plate members fixed on top of one another to create a thicker base.
- Engineered timber products: In some cases, engineered wood products might be used instead of traditional sawn timber.
The size and type of sole plate used are determined by building regulations, structural calculations, and project-specific details to ensure the stability and integrity of the timber frame structure.
