The Benefits of External Wall Insulation

External wall insulation is a solid wall insulation system that is fitted to the external walls of a domestic home that insulates and protects the wall from the elements. Once this insulation is fitted, it is covered with render cladding to give the insulation durability and an attractive appearance. This render cladding is available in a range of finishes:

  • Textured,
  • Traditional stone appearanced,
  • Low-maintenance thin coated.

Whilst it may sound like a lot of work, it is well worth it due to the many benefits it offers you and your home:

Lower Fuel Bills
External wall insulation (EWI) is designed to reduce the amount of heat escaping your home, meaning that you can not only heat your home faster, but keep it warmer for longer. Reducing the amount you need to spend on heating your home.

Protect Your Home
EWI protects the home’s structures and waterproofs against damp.. No more worrying about water getting in and damaging your walls.

Make Your Home Attractive
Whether you are looking to mimic the existing façade on your home or completely remodel it, with the wide range of finishes available on EWI the choice is yours. Create a home that not only keeps the warm in, but reflects your personality.

Reduce Your Carbon Footprint
Due to the reduced need to have your heating on for longer, therefore using less fuel and energy you are helping to reduce carbon emissions.

Less Disruption During Installation
EWI has less of an impact on your everyday life when being installed than internal wall insulation, as you are still able to use the rooms. The only disruption may come from the scaffolding outside the home, but as this insulation goes on the external walls your room sizes won’t be affected.
