Wall logs, beams and boards

Standard Wood Using Rules

Which timber we stock and use in our projects. This is a quick reference for sales managers.

How to read this page

All sizes are in millimetres.
Wall thickness means the thickness of the wall logs in the building. Most elements are chosen by it.
Boards are listed as thickness × width.
Only products we actively use are listed. For anything else, contact the project coordinator.

1. Quick guide: what goes with each wall

Pick the wall thickness first, then read across. A dash means the element is not standard for that wall.
