Types of door joints for wooden doors

There has been lots of discussion over the years about the pros and cons of what is the best type of joint for constructing doors, this is a short piece of info to try and clear up the details surrounding Mortice & Tenon joints compared to Dowel joints.

To clarify, the traditional method is Full Through Mortice and Tenon Joints which are then wedged top and bottom of each Tenon and glued in position, the Tenon goes through to the door edges, this has always been perceived as the best joint.

Stub Mortice and Tenon Joints are similar to above but do not show through on the door edges and rely on the tightness of the construction and the glue to hold the door together.

The newer "Splined" Dowel Joints can be just as effective, imagine if you will that a Splined dowel is like a fan or table napkin that has been folded time and again, it has lots of surfaces, if the dowel could be laid flat you would find that the surface area is comparable to a traditional door joint.

The dowel joints are definitely quicker when it comes to mass production and are therfore used on virtually every internal door and lots of external doors.

There are numerous other types of timber jointing methods but we have restricted this small blog to the types of joints used in full size house doors and avoided discussing any types of jointing for kitchen unit doors etc.

All doors supplied by carry the same guarantees regardless of joints.
