F.A.Q

External wall insulation is applying insulation on the external solid wall of a home or building. It generally comprises two parts or layers:

  • An inner layer with excellent insulating properties
  • An exterior layer of mineral or synthetic render for weather protection and an aesthetic finish.

External wall insulation will help save energy, which leads to a higher EPC rating. Not only does EWI make your home more energy-efficient, but it also improves its appearance

Insulating external walls is costlier compared to insulating internal walls. The cost of external wall insulation depends on the type of house and the number of walls you want to insulate. It can run up to £16,000 for a large detached house and be anything near £9,000 for a semi three-bedroom home.

Some of the benefits of external wall insulation include:

  • Saves energy and money
  • Makes your home more energy-efficient and improves EPC rankings
  • Improves the look or appearance of your home.
