Partition walls, internal insulation

Partition walls that separate two rooms are usually constructed with a wooden or metal frame – also known as a stud wall.

Stud wall insulation is used to fill the space within these frames to significantly improve the sound and fire-resistant qualities of any residential or commercial property.

Why do we need partition wall insulation?

Splitting one room into two – for example a large bedroom within the home, or when designing an office floor plan – is best achieved by building an insulated partition wall. Good quality insulation helps to improve acoustic performance and fire resistance within this space.

A soundproof stud wall will reduce the acoustic transfer between rooms, which is especially important in working environments. The partition insulation must also be highly fire resilient1 – especially with wooden stud walls that are at greater risk.

Stud walls are suitable for many buildings with the available space. They are quick to erect and easy to move when layouts change. You can apply various finishes and designs for high end properties – or use regularly available boards with a paint finish to complement a chosen colour scheme.

Benefits of ROCKWOOL stud wall insulation include2:

  • Improved acoustic capabilities
  • Flexible fitting
  • Water repellent properties
  • Strong sustainability
  • Fire resilience


Calculator and savings

A stud wall is not designed to focus on financial savings. Instead, it is a room divider that brings additional comfort and safety through its acoustic and fire resistance properties.

Based on locally available test reports, any wall can be designed and calculated to meet requirements. From there it is a small step to determine the amount of material to install a stud wall within your residential or commercial property.

Using ROCKWOOL partition insulation will save you time determining which product to use, as our range has good acoustic properties and is fire safe.

With our products, the need for an additional layer of finishing boards can be avoided to reach the same acoustic or fire performance. When compared to solid walls (such as brick) the lower weight of the wall and the ease of moving a wall are a huge cost advantage.

Sustainability and energy efficiency

Higher density stud wall sound insulation enhances comfort and reduces noise pollution – a common challenge in modern developments.

ROCKWOOL products used between stud walls, made using natural materials, are highly sustainable. Stone wool is crafted from volcanic stone – and the earth produces more than 38,000 times the amount used yearly to produce the insulation.5
