What is a Wall Section?

Listen to this Topic

Section diagrams (or wall sections, or simply ‘sections’) are one of the more important tools used by the contractor to build your house. A section is literally that – a cross section diagram of a given part of the house, showing exactly what goes where.

A section diagram will show in great detail what the foundations, walls, floor systems and roof are made of, and how they’re made. This includes details on things like:
• Specific Construction Materials
• Sheathing
• Insulation Requirements
• Heights
• Framing Sizes and Depths
• Vents
• The Shape and Construction of the Eaves
• The Pitch of the Roof etc.

A wall section is likely to be accompanied by a lot of supplementary notes explaining in detail the many different things it’s designed to show, and will use the same shading, symbols, and abbreviations that you’d see in the other plans.
