On French Doors: What Are Mortise-and-Tenon Joints?

Renewal by Andersen® of Kansas City’s hinged French patio door is iconic not only in style but also in performance. In addition to its advanced features, its classic craftsmanship and mortise-and-tenon joinery are excellent proof of it.

If you have no clue what mortise-and-tenon joints are, read on to learn why you want your French doors to be constructed with them:

What Are Mortises and Tenons?

The mortise is a hole cut into a piece of wood. Its mate, the tenon, is a protuberance crafted on the end of another piece.

To remain sturdy decades after doors installation, precise measurement of the two is paramount. The dimensions of the mortise walls must match those of the tenon. When cut by machine, the size of the tenon must be one-half of the wood’s thickness. When fitted and glued properly, the pieces joined by the mortise and the tenon then become extremely hard to move, let alone separate.

Are Mortise-and-Tenon Joints the Best for Traditional Doors?

Any experienced woodworker would attest that mortise-and-tenon joinery is perhaps the most popular choice for door construction. Actually, this means of connection between two pieces of lumber at ninety degrees is a favorite when making heirloom furniture. The incredible sturdiness of mortise-and-tenon joints renders door frames strong, worthy to be passed down to the next generation.

Why Are They Not Used for Contemporary Doors?

Since our contemporary sliding doors have thin boards, we decided to use a different type of frame joinery to ensure strength. Plus, we want to conceal the unappealing end grain in the lumber for a cleaner and sleeker finish.
