Everything You Need to Know About Partition Walls

A partition wall, otherwise referred to as a ‘stud’ wall, is a structural feature that enables you to divide a large interior space into different rooms or smaller sections.

This can transform a general downstairs space into a separate kitchen and dining room, for example, or help you to create an additional bedroom, home office or similarly compact space for a range of different purposes.

In most cases, a stud wall is constructed using a timber frame complete with a secure plasterboard covering, in order to make the wall functional and capable of hanging pictures. But how do you create a stud wall, and what regulations do you need to keep in mind as part of the project?

Addressing the Technical Elements of a Stud Wall

Let’s get started by considering some of the technical elements of building a partition wall, so that you can begin to flesh out your project. For example:

● The Importance of Equal Spacing: Proper construction is crucial to the stability of your partition wall, particularly when it comes ensuring that your studs are equally spaced through the wall. Typically, studs are set apart 16” (or 400mm), as this creates a sturdy and solid wall that can stand the test of time.
● Lining up Your Studs With Plasterboard Edges: The equal spacing of your studs will also make it easier to install and fix plasterboard. Ideally, your wall studs should line up with the edges of a particular sheet of plasterboard, creating a scenario where you can secure it quickly and with the minimum of fuss.
● How Thick Should the Partition Wall be?: Ok, we hear you ask, but what about the optimal thickness of a partition wall? Well, your vertical timbers should be 50mm by 100mm, as this affords the structure the durability and sturdiness that’s crucial to any interior wall (even on that isn’t load bearing). Plasterboard will then add up to 12.5mm to the width of the wall, before a final coat of skim plaster is added.

What Regulations Pertain to a Stud Wall?

There are various regulations to keep in mind when building a partition wall, some of which pertain to insulation.

More specifically, sound insulation is a prerequisite of any stud wall construction, especially the structure that divides a bedroom from another room (such as a bathroom or WC). This can be achieved using sound-resistant plasterboard, or by filling the gaps between the studs with sheets of dense insulation material.

If you’re dividing a large bedroom into two smaller rooms, you’ll have to ensure that there’s at least one window in each of the new interior spaces.

The reason for this is simple; as it ensures that the property offers a viable escape route in the event of fire.

If the floor level outside your new window is more than 4.5 metres, you’ll also need to incorporate an alternative to jumping from the window (such as a ladder or fire escape).
