What is External Wall Insulation?

External wall insulation is a type of insulation that is added to the outside of your walls. The insulation process consists of attaching two layers to the outer walls; one for insulation and the other to protect against the elements. External wall insulation is a way of limiting heat loss from your home.

How does External Wall Insulation work?

Insulation products such as expanded polystyrene (EPS), mineral wool, phenolic resin or woodfibre are attached to the exterior of the property. The most popular choice is EPS as it’s cheaper than the alternatives and easier to install.

Once the insulation is installed to the outside walls, a weather-proof layer is applied. The protective render is available in a variety of colours and finishes to suit the look of your property. You can choose from pebbledash, a brick-effect design, composite cladding or brick slips.

External wall insulation works to prevent heat from escaping from the outside walls of your property and to improve your home’s energy efficiency.

Is External Wall Insulation right for me?

A poorly insulated home can mean that heat energy is being lost at a quicker rate. Without proper insulation more heat is required to maintain a comfortable temperature throughout your property. Increased energy usage will also result in higher heating bills.

If you feel that your home is not retaining heat as efficiently as it could, external wall insulation could be a good solution for you. External wall insulation is right for you if your aim is to improve the energy efficiency of your home, keeping your rooms warmer for longer.
