Benefits of external wall insulation

Reduce heating bills

20-30% of your home's heat loss occurs through your walls. Cavity insulation (if applicable) will reduce heat loss in your home.

More comfort

External insulation will help make your home more energy efficient and comfortable to live.

Reduce your carbon footprint

Reducing your home's heat loss via its walls will reduce your energy consumption. As you will then be using your heating less - you will also cut down on your greenhouse gas emissions.

What's involved?

External insulation involves fixing insulation materials such as mineral wool or expanded polystyrene slabs to the outer surface of the wall. The insulation is then covered with a special render to provide weather resistance. A steel or fibreglass mesh is embedded in this render to provide strength and impact resistance.

Although external insulation is an expensive insulation solution, it can also resolve other issues, such as rain penetration, poor air tightness and frost damage.

The optimum solution for your specific case should be discussed with the Contractor.
