Partition Wall Insulation

Find partition wall insulation materials for residential, commercial and refurbishment projects with one of our depots. Our range includes insulation solutions for internal stud walls, room partitions and compatible wall systems, helping builders, contractors and installers source materials for thermal and acoustic performance.

Acoustic Insulation for Stud Walls

Insulating a partition wall can help reduce sound transmission between rooms and improve the comfort and privacy of a building's occupants. Acoustic mineral wool and glass wool slabs are commonly used within suitable timber or metal stud partitions to help absorb sound travelling through the wall structure.

The performance achieved depends on the complete partition construction, including the insulation, framing, plasterboard layers, joints and perimeter details. Select materials designed for your chosen wall system and check the manufacturer's technical guidance.

Types of Partition Wall Insulation

Different projects require different insulation materials. Mineral wool and glass wool slabs are popular choices for acoustic insulation within stud walls. Rigid PIR insulation boards and insulated plasterboard may also be suitable for specific thermal insulation or drylining applications, depending on the wall design.

Where fire performance is important, choose products specifically tested and specified for the intended application. Not every insulation board or slab provides the same acoustic, thermal or fire performance.

Choosing the Right Insulation for Partition Walls

Before selecting partition wall insulation, consider the stud depth, available cavity space, required acoustic performance and any thermal or fire protection requirements. Check the product thickness, dimensions, coverage per pack and compatibility with the partition system to ensure the materials meet your project specification.

For projects where sound reduction is a priority, consider the complete wall assembly rather than insulation alone. Correct installation and suitable plasterboard layers can make an important difference to the finished partition's performance.
