Dry Lining Insulation

Dry lining insulation can be applied to the inside of external walls – primarily to improve a building’s thermal performance.

Additional qualities such as acoustic absorption and fire protection can also be achieved, depending on where the insulation is installed.

Traditionally, dry lining is used to insulate the inside of a solid external wall with boards or panels . These can include a finish for an aesthetically pleasing design, when installed on a room-facing surface. This process can also be used for to enhance energy efficiency and room comfort.

In some markets, dry lining can also be used in conjunction with stud wall, cavity wall and ETICS solutions.

Why do we need dry lining?

Home energy use is responsible for a quarter of energy-related greenhouse emissions1. As global energy demand increases – with weather conditions behind a fifth of this rise – creating comfortable, energy-efficient properties is essentia2.   

Internal dry lining can have a big impact on energy savings, whether applied to new buildings or retrofitted. It improves the thermal performance of external walls, retaining cool air where it needs to be during warm weather. 

Various products and application methods can be used to suit many types of constructions, often following a similar installation process to

Key benefits include:

  • Significant energy savings
  • Improved fire safety
  • Greater acoustic performance

Calculator and savings

The amount of insulation required depends on the size of the wall surface where it is being applied. Calculate this to determine how much material you need.

When installing between a stud wall, products may be available with specific width or flexible edge to match stud spacings – and reduce the material loss from cutting down to size. The ideal thickness links to the stud thickness, enabling the best performance possible.

Use our ROCKWOOL U-value calculator to determine the thermal performance of the building’s walls/roofs, and possible cost savings. For more details on technical specifications, visit our ROCKSPEC Specification Toolkit.

The usage of internal dry lining is very much dependent on the building tradition. It can also be used in combination with a cavity wall granulate filling, or a layer of ETICS insulation on the outside of a wall.

Sustainability and energy efficiency

All ROCKWOOL products are made from one of the most abundant natural materials around – volcanic rock. They can be infinitely recycled5.

Through improving the thermal performance of a building, dry lining insulation also improves its energy efficiency and reduces the amount of energy consumption required for comfortable heating and cooling levels.

How do I insulate my facade made out of bricks?

There are various solutions for insulating a brick façade, including products for internal dry lining or insulating from the inside, without changing the exterior aspect of the façade.

If you want to change the aesthetical aspect of the façade, we offer solutions such as ETICS (rendered façade) and claded façades (Rockpanel).



How do I insulate a wall in a basement?

Make sure you have a proper vapour barrier right behind your drywall to create a solid air break.

There are many smart vapour barriers that change their permeability to allow any humidity present to escape, so you don’t end up with trapped condensation.

Does dry lining need plastering?

When dry lining insulation is applied to the internal facing walls of rooms, it requires a finish. Some products include a plasterboard finish, which can be directly painted on, but a wet plaster finish is not required.
