why are my walls so cold

Internal Wall Insulation


It’s estimated that up to 50 per cent of a building’s lost heat escapes through the walls. For homeowners that’s a lot of energy to lose, and it quickly leads to mounting gas or electric bills.

Internal wall insulation can help you to lower your energy bills by keeping the heat inside your property. If you’re interested in learning more about internal wall insulation, contact Danford, Brewer & Ives’s team of experienced insulation installers to find out more.

What Is Internal Wall Insulation?

Internal wall insulation is designed to insulate the inside of a home by forming an effective barrier that traps heat and stops energy from being lost to the outside. It’s most commonly used to insulate solid stone or brick walls that have no insulated cavity space and therefore lose an incredible amount of heat through the walls.

How to Install Internal Wall Insulation

The primary goal of internal wall insulation is to provide an insulating barrier that protects against heat loss. This can be achieved in a number of ways.

The most popular method of insulation is to build a second layer of ‘wall’ against the existing solid wall, leaving a space in between that can be filled with effective insulating materials.

Internal wall insulation can also be combined with damp proofing, as a damp-proof course and other forms of damp protection not only create a waterproof barrier but act as insulators too.

The best method of insulation depends on a number of factors, including the type of wall, the size of the home, and the extent of the heat loss problem. For this reason, it’s important to seek professional advice when installing internal wall insulation.

How Thick Should Internal Wall Insulation Be?

To work as an effective insulator, internal wall insulation must be at least 60mm thick. The exact thickness of the insulating material will depend on how much space is available inside the room; where possible, it should be extended to 100mm in thickness.

Homeowners need to bear in mind that the thicker the insulation is, the more effective it is at retaining heat. Obviously, thicker insulation takes up more space though.

How Much Does Internal Wall Insulation Cost?

The overall cost of an internal wall insulation project depends on a number of factors. The major points to consider are:

  • Type of material used for insulation
  • The number of rooms being insulated
  • Time taken for the work to be carried out

Homeowners also need to factor in any redecoration work that needs to be carried out, as well as electrical fittings that might need to be moved or replaced to make way for internal wall insulation.

Average costs for internal wall insulation work out to be around £50 per square metre, but you’ll need to have a survey carried out for a more accurate cost estimate.
