After all, we are fully aware of just how much these windows contribute to a building. Not to mention, it is a far cheaper alternative to a full on replacement.

Many regular designs of sash windows come with thick frames. Typically, they are as thick as 174mm. This is considerably thicker than what the window would have been like during its introduction. In a period structure, this can look out of place. Ensuring that the frames are an ideal fit for your property is tricky when using cheaper, thicker double glazing units. This is something several suppliers of timber windows tend to overlook. We are going to go into more detail as to why it matters to get the depth of your frames correct.


The majority of period properties come with an L shape recess within the walls. This is what the sash window frame sits in. The frame’s thickness must match the recess’ depth. Normally, this is between 140mm and 150mm. It has to so that the frame can sit flush against the wall’s interior.

Protruding frames

It is possible that the sash frame will be too thick. If this is the case, then you can expect it to protrude into the room. Initially, this might not seem like an issue to you. However, with thicker sashes and frames, you must pack the architrave out. You must do so by as much as 2 inches. This can appear incredibly bulky in the end. The effect is going to look even worse on a splayed bay thanks to all the angles.
