In this section, you will find some of the most commun terms used in timber frame. 




Joinery is the most structurally astonishing and complicated aspect of timber framing. In its simplest form, joinery is the art of connecting large timbers to one another by Mortise and Tenon.

- A Mortise is a cavity carved into a beam that will receive a Tenon.
- The Tenon is the reduced end of a beam that inserts into the mortise.

A wooden peg is then driven through both assembled members to lock them in place.


Bents (here in red) are like slices of bread that make up a loaf. Their major function is to transfer the roof’s load evenly throughout the frame to the foundation.

Bents are primarily composed of post, tie beams, and trusses (rafters). To stiffen them and keep bents from racking braces, collar ties, and struts are added.

Finally, to connect each bent of a frame together, connecting girts, top plates and ridge beams are used.


Trusses are the triangle forms that transfer the weight from the roof to the rest of the framework or bents. Depending on the span that they cover or the homeowner’s preference, trusses can be designed several ways.

SIPs panels

• two facings: OSB panels (Oriented Strand Board)
• an adhesive that bonds the facings to the core
