Work out your wall type

If your walls are solid, they very probably aren’t insulated – but the first step is to figure out what kind of walls you have. If the brickwork on the outside of the home is visible, look at the pattern of the bricks to discover how the wall was constructed.

What is solid wall insulation?

A typical solid-wall home loses approximately half of its heat through the walls. Insulating these walls will retain the heat inside for longer and lower your heating expenditures significantly. Insulating solid walls both internally (from the inside) and externally (from the outside) is a huge undertaking in terms of cost and disruption.

How much does solid Wall Insulation Cost?

Internal wall insulation costs vary depending on the type of insulation chosen and the existing wall’s condition. Under the government’s ECO4 initiative, grants for solid wall insulation are offered for qualified families. If you meet the criteria then you will benefit by free solid wall insulation. Government initiates the ECO4 scheme to provided free insulation and it is non repayable grant.


Internal solid wall insulation:

  • Solid wall insulation, which works by adding a layer of thermal material to the existing inner wall, may be acceptable for homes built of brick, stone, or concrete construction. This will shrink your rooms slightly, yet you may find that by making a cold wall warmer, you can increase the amount of usable space in a room.
  • Solid wall insulation can be insulated by attaching rigid insulation boards to the existing wall or by constructing a stud wall into which sheep’s wool insulation, mineral wool insulation, or other insulation material can be introduced.
  • Internal Solid wall insulation is often less expensive to install than external solid wall insulation, which is a significant benefit..
  • It will lower the floor area of any rooms where it is used by a small amount (the thickness of the insulation is around 100mm).
  • Requires the removal and reinstallation of skirting boards, door frames, and external fittings.
  • Although specific attachments are available, it might be difficult to secure large things to inner walls.
  • This cannot be done without first addressing any issues with penetrating or rising moisture.

External solid wall insulation

  • Fixing a layer of insulating material to the wall, then covering it with a special sort of render (plasterwork) or cladding, is what external solid wall insulation entails.
  • Can be used without disrupting the household and does not reduce the size of your home’s floor area.
  • Weatherproofing and sound resistance will be improved
  • By protecting the brickwork, it extends the life of your walls
  • To save money, it’s best to install it at the same time as outside renovations
  • If the outer walls are structurally unsafe and cannot be fixed, it is not recommended
