External Wall Insulation

External Wall Insulation (EWI) systems comprise of rigid insulation boards fixed to the outside of your home and are then over-coated with a weather protective, hard wearing, breathable render. It is then pebble-dashed which is available in a choice of attractive finishes.

External wall insulation involves fixing a layer of insulation material to the wall, then covering it with a reinforcement and a special type of render. The finish is usually a textured render, pebble-dash or sometimes a brick slip or a brick effect render finish could be used.



The benefits of external wall insulation:

  • Can be applied with minimal disruption to the household and its occupants
  • No internal access is required
  • Does not reduce the floor area (living space) of the property
  • Improves the appearance of the property – potentially increasing the property’s value
  • Improves weatherproofing and sound resistance
  • Can make the building more airtight, reducing drafts and heat loss
  • Increases the life of the existing property by protecting the existing substrate from the weather
  • Reduces condensation on internal walls and can help prevent damp
  • Fills cracks and gaps in the brickwork, which will reduce draughts
  • Increases the life of your walls by protecting the brickwork
