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 heat during cold periods and keeping 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 U-value calculator tools and technical support where available with your local ROCKWOOL organisation. They can help you determine the exact product and thickness needed to fulfil your requirements.

Why choose ROCKWOOL solutions?

A wide range of ROCKWOOL products are available to meet local building standards and practices.

These are all designed for easy installation, either in between studs or adjacent to the inside of an external wall.

Even where space is limited when renovating a building, applying any amount of dry lining insulation brings a substantial increase of comfort and energy savings to the occupants.

Improved energy efficiency, acoustic insulation and fire protection creates a safer, more comfortable living environment.

Benefits of ROCKWOOL solutions include³:

Thermal performance – improve energy efficiency
Fire resilience – limit fire spreading risks
Acoustic absorption – reduce the impact of noise pollution
Aesthetics – finish for room facing slabs, boards and panels
Circularity – reusable and recyclable

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.

Installation

For dry lining walls with studs, design, build up and placement is mostly the same as for partition walls. The insulation is placed between the studs, with flexible edges making installation easy.

Dry lining boards, with a finish layer attached, are normally applied to the inside of an external wall, with the finishing board facing the room. Cement mix or other locally available tools can be used to glue the board onto the outer wall.

You can also make cut-outs on the back of the product using specific cutting tools to cover electric piping.

Key tips⁴:

Use appropriate glue – Depending on the glue type, it should be applied in a dotted or continuous layer on the back side of the insulation material, before pushing the board in place against the outer wall.
Adjust as you install – Small adjustments for perfect levelling can be done while placing the board, to avoid thermal gaps.
Measure the walls – Accurately size up your walls and use extra material, as cutting may be required to ensure perfect friction fitting.

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.
