Internal Wall Insulation

Internal wall insulation can be used in both commercial and residential properties to improve indoor comfort and boost energy efficiency.¹

There are various methods of adding insulation for inside walls – each designed to reduce thermal transmission, increase acoustic performance or raise fire safety.

Why do we need internal wall insulation?

Introducing high quality interior wall insulation is one of the best ways to prevent loss of circulated cool air, protect against fire risks, and improve acoustic capabilities.

It improves energy performance and creates a comfortable home or working environment suitable for all types of internal walls:

Partition walls – Non-load bearing walls used to divide a room. Commonly a wooden or metal stud wall with plasterboard finish or similar.
Dry lining walls – Similar in build to a partition wall, but placed on the inside of the outer wall. This type of internal wall is designed around improving comfort.
Separation walls – Also known as a party wall, these separate adjoining flats, houses and rooms between residential properties.

Applications can be easier and more accessible for certain properties, such as flats. They also have no impact on the external appearance, such as with dry lining walls where the insulation can be installed before the cladding, which is then painted over.

For separation and partition walls, they improve the soundproof qualities between rooms and properties.

Benefits of ROCKWOOL internal wall insulation include:

Reduced heat gained
Protection against fire risks
Cost-effective installation
Blocking and absorbing sound
Matching environment aesthetics

Calculator and savings

The amount required, and the precise cost to install, will depend on the size of your property, the thickness of its walls, and how many are being insulated.

With dry lining often done to increase the living comfort the insulation thickness is based on energy efficiency requirement.

Insulating the separation wall between dwellings will save on the energy bill as it will prevent heat transfer from one to the other.

Why choose ROCKWOOL solutions?

Our products are suitable for improving the thermal, acoustic and fire properties of three main types of wall:

Separating wall – ROCKWOOL products provide natural acoustic, fire and thermal insulation properties. These are ideal for improving the energy efficiency and safety of party or separating walls.
Partition wall – ROCKWOOL stone wool insulation provides sound proofing and fire prevention, enhancing privacy and comfort.
Internal dry lining – Placed against the inside of an outer wall, internal dry lining is designed to increase comfort and thermal performance.

Utilising the seven strengths of stone, ROCKWOOL applications for internal wall insulation are²:

Fire resilient
Water repellent
Acoustic absorbing
Thermal maintaining
Robust and durable
Reusable and recyclable

We provide a range of dedicated products for various internal wall applications, meeting the specific needs and requirements of that application. These include thermal products to reduce energy bills, acoustic products to substantially reduce sound going through the wall, and firesafe products to achieve the highest fire resistance.

Applications

Insulation

Partition Wall Insulation | ROCKWOOL

Partition stud wall insulation is one of the best ways to insulate room-dividing walls.

Insulation

Dry Lining Insulation | ROCKWOOL

Dry lining insulation enhances the thermal performance of external walls and saves energy.

Installation

There are a few different methods of interior wall installation. The method of installation will vary depending on your chosen type:

Fit rigid internal wall insulation boards with dry lining.
Put insulation between solid blocks for a party wall.
Build a metal steel frame or wooden stud wall and fill it with insulation material.

Key tips:

Measure accurately – Interior wall insulation can take up space in the room where it’s installed. Consider the depth and how it will affect your space.
Fix prior problems – When installing dry lining, fix cracks in existing walls to stop rainwater from coming in. ROCKWOOL insulation is water repellent, but it’s essential to fill in cracks first.

Sustainability and energy efficiency

ROCKWOOL internal wall insulation is focused on sustainability and enhancing the energy efficiency of buildings.

Our products are made from one of the most abundant natural resources on our planet – rock – with the earth producing 38,000 times more stone than we use annually to create stone wool.³

It’s not just energy consumption that our internal wall applications aim to tackle, of course. Noise pollution is a major challenge in the modern world and the acoustic capabilities of our insulation work towards reducing this – creating comfortable and sustainable living.
