A Guide to Architraves

What is an architrave?

An architrave is like a frame, which serves as a decorative trim for your door or window.

There are several different types of architraves, but not all windows will have one. If your window does have an architrave, we will need to identify the style in order to determine how to measure your shutters and ultimately, how they will be installed.

HOW DOES EACH FRAME TYPE WORK WITH AN ARCHITRAVE?

Z-Frame with architraves

A Z-frame sits inside the recess, with a lip that extends 19mm around the architrave. The Z-frame works very nicely with a Square or Bullnose architrave, or with a square set window (i.e. no architrave). If you have a decorative architrave, you may want to avoid a Z-frame as it will cover part of the trim.

INSIDE L-FRAME WITH ARCHITRAVES

An L-frame sits inside the window recess, and can work with any architrave. A particularly good option for decorative architraves, as it won't cover any part of the trim.

outside L-FRAME WITH ARCHITRAVES

An outside L-frame can be installed to any type of architrave, as long as there is 38.1mm of flat surface to install the frame. If you have a decorative architrave, there may be a flat surface at the centre of the architrave to install an outside mount. (This requires a different measuring technique to a normal outside mount.)
