Introduction

Installing a stud wall is one of the most commonly undertaken projects by DIY enthusiasts, as they look to split a room into two smaller ones, or perhaps add a functional wall to the kitchen area. Stud walls are relatively easy to construct and fit, so long as you work methodically and follow the relevant building regulations.

If you are planning on installing a stud wall in your property then the advice below on building regulations should greatly help you achieve a satisfactory end result.

The importance of regulations

Whilst usually you will not have to apply for planning permission to insert a stud wall, there are certain building regulations that must be adhered to in order to ensure safety of anyone who enters the property. If you fail to keep to these regulations then it could cause problems at a later date; such as if you decide to sell the property.

If a stud wall that does not comply with regulations comes to light then you may be forced to remove the alterations and return the property to its previous state.

Fire safety

The most important factor to consider when splitting a room into two smaller rooms is the provision of escape routes in the event of a fire. In most situations this will be overcome by the installation of a window in both rooms. Be aware that any windows that are higher than 4.5m metres from the outside floor level require a fire escape ladder or other alternative to jumping.

If you are splitting a ground floor room, you could of course fit a new door if appropriate. If your property is three storeys high or more and if your intended stud wall will face onto a stairwell, then you must use fire resistant plasterboard. This is to prevent the fire from spreading too rapidly; allowing everyone in the property enough time to get out safely. If the stud wall will have a door in it then this must also be fire resistant and utilise a self-closing mechanism.

Soundproofing

If your stud wall will be used to separate a bedroom, bathroom or w/c from another room then you will need to use some form of sound insulation. This can be done by either using sound-resistant plasterboard, or by inserting a thick insulation material in the spaces created by the opposing plasterboards and the studs. There are various sound-resistant materials available and a quick search online will help you identify which is best suited for your requirements.

Structural considerations

In most instances a stud wall installation will be non-loadbearing and as a result it will not require any additional structural support. That said, in situations where a stud wall will run parallel to floor joists, it could be that a second joist is required next to the joist to which the stud wall will be fastened to. This will be dependent on joist spacing and the weight of your intended stud wall. If you are unsure as to whether you need this additional joist then it is advisable to consult a structural engineer.

Ventilation requirements

Where your stud wall will lead to the creation of a new room, you must take into account the needs for ventilation. This of course means a window so that you can quickly purge the room should you need to. In addition, there must some form of trickle ventilation; whether via the window frame or a wall vent. An electric extraction fan should be considered where the stud wall will create a new bathroom, w/c, kitchen or utility room.
