Do you have old tired solid existing render?

What is External insulation?

External wall insulation involves fixing a layer of insulation material to the wall, then covering it with a special type of render (plasterwork) or cladding. The finish can be smooth, textured, painted, tiled, panelled, pebble-dashed, or finished with brick slips.

  • It can be applied without disruption to the household does not reduce the floor area of your home
  • It will renew the appearance of outer walls.
  • It will improve weatherproofing and sound resistance.
  • It fills cracks and gaps in the brickwork, which will reduce draughts.
  • Increases the lifespan 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).
  • It is best installed at the same time as external refurbishment work to reduce the cost.
  • It may need planning permission – check with your local council.
  • It requires good access to the outer walls.
  • It is not recommended if the outer walls are structurally unsound and cannot be repaired.



Is External Wall Insulation an Option Worth Pursuing?

So, in summary, there are a number of issues to be addressed prior to installing external wall insulation, but the benefits are numerous, including:

  • Reducing heat loss and energy bills
  • Reducing draughts and increasing the sense of comfort
  • It does not disrupt the house while being installed
  • It does not reduce internal floor area
  • It allows walls to contribute to thermal mass (the ‘tea cosy’ effect)
  • It improves weatherproofing and sound resistance
  • It increases the life of the wall
  • It reduces condensation on internal walls
  • can be used to cover over old solid existing render (saving removal of old render)
