Partition wall insulation is insulation materials designed to be applied to the spaces in partition walls or stud wall frames. Partition walls are made up of timber or metal frames built to split one room into two within commercial or residential buildings. The materials are frequently made up of high-performance, rigid polyisocyanurate (PIR) featuring foil facings on both sides or mineral wool slabs and other forms of insulation depending on the method of installation being applied.

How is partition wall insulation installed?

Always call a specialist before installing partition wall insulation to prevent problems occurring in the future and damages being made to the property.

Once the partition or stud wall is complete you can begin to apply insulation materials. First, measure the dimensions of the wall and apply the plasterboard to one side of the stud wall by using a screw and fixing the plasterboard to the timber frame.
Then measure the spaces in the stud wall and cut your chosen insulation material to size. Most insulation can with cut with a Stanley knife or hand saw. Foil tape can also be applied over any insulation materials that are butted together or over where the timber battens and the insulation materials meet.

The other side of the wall can now be fitted with plasterboard. The plasterboard can be cut and applied to match the dimensions of the wall and applied by screwing the plasterboard into the timber battens.
Then measure the vertical studs on the end of the wall and apply plasterboard to cover. Corner beads can be applied to the corners using clout nails and scrim tape can be applied to cover the joints and avoid cracks on the joints when plastered.

The wall is then ready for finishing applications such as plaster and paint.

Why do I need partition wall insulation?

When splitting one room into two this is best achieved by building an insulated partition wall. Good quality insulation can help to improve acoustic performance, thermal conductivity, and fire resistance within the space.

A soundproof stud wall is recommended to prevent acoustic transfer between rooms to make a more comfortable environment.
Stud walls are suitable for many buildings within the available space such as in commercial buildings to create office spaces or in residential buildings to create rooms or storage spaces or wardrobes. Partition walls can be quick to install and can be moved if needed to change the layout of the space make redesigning your home easy.
Partition wall products are extremely durable and should last as long as the building when installed correctly.
Partition wall insulation is manufactured by several brands such as Rockwool, Isover, Knauf, and others.

Rockwool Flexi Slab
Rockwool flexi slab has been designed for multi-use purposes. Rockwool is a mineral wool flexi slab which provides acoustic and thermal qualities with a unique flexible edge along one side designed to ensure easy and easy fit. It is also lightweight and easy to cut and handle. The insulation can be installed between fresh timber and will expand into the looser space as the timber dries out and shrinks back while other insulation products can often become displaced causing cold spots and poor acoustics.
