What is it?

What is External Wall Insulation?

The majority of homes built before the 1930’s and 1920’s were built with just one single solid wall which inevitably means that a lot of heat is lost. This makes your home very energy inefficient and can cost you money on your energy bills.

External Wall Insulation is fixed to the outside wall meaning very little disruption to you and those living in it. The external wall is fitted to the outside of your property with a very attractive render applied over the top of it. Not only will it make for a more energy efficient home but it will often improve the appearance of your home.

The first step is to remove all the any satellite dishes, aerials and vents. The insulation boards are fixed to the building which are coated with adhesive and a reinforcement product.

Finally, a render finish is applied to your walls, so your property looks like new again and aerials, vents etc ae reinstalled to your property. In effect you are left with a very attractive exterior and an insulated cavity wall meaning you lose less energy and spend less money on heating bills.


What Should Be Considered When Choosing
External Wall Insulation?


  • It can be applied without disruption to the household
  • It does not reduce the floor area of your home
  • Renews the appearance of outer walls
  • Improves weatherproofing and sound resistance.
  • Fills cracks and gaps in the brickwork, which will reduce draughts
  • Increases the life of your walls by protecting the brickwork
  • Reduces condensation on internal walls and can help prevent damp (but will not solve rising or penetration damp)


  • Is best installed at the same time as external refurbishment work to reduce the cost
  • May need planning permission – check with your local council
  • Requires good access to the outer walls
  • Is not recommended if the outer walls are structurally unsound and cannot be repaired.
