External Wall Insulation

Insulating your solid walls could cut your heating costs considerably, because solid walls let through twice as much heat as cavity walls do.This can also change the appearance of your property making it more pleasing to the eye.

External wall insulation:

  • can be applied without disruption to the house
  • 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
  • requires good access to the outer walls
