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.
