If you want your home to be more energy-efficient, you may be considering external wall insulation. And, you may be interested to know that thermal efficiency is just one of many advantages of improving your home in this way. Here are seven benefits of external wall insulation.

Increases thermal efficiency

The main benefit of external wall insulation is that it increases the thermal efficiency of your home. This means you can lower your heating bills by up to 50% and reduce your carbon footprint. The more thermally efficient your home is, the less heat escapes through the roof and walls, meaning you aren’t as dependent on the central heating and whatever heat is generated is retained. External wall insulation also lets heat escape in the summer, keeping the property cool when it is hot outside.

It is the best option for solid walls

If your property has solid walls, rather than cavity walls, then external wall insulation is the best option to insulate your home. Internal wall insulation can be cheaper than external wall insulation, but the installation of internal wall insulation is very disruptive and it makes the rooms of your home smaller. External wall insulation is always recommended for buildings with severe heating problems as the thermal efficiency it provides is much greater.

Saves on internal floor space

Internal wall insulation involves attaching the insulating material to the interior walls of the property, which will reduce your available floor space. If you choose external wall insulation, you will instead retain this floor space whilst still getting the benefits of increased thermal efficiency.

Minimises cold bridging

A cold bridge is an area of a property where there is a gap in the insulation, causing cold spots that are susceptible to condensation and mould when warm moist air in the property passes through them. One of the benefits of external wall insulation is that it minimises cold bridging because it provides continuous insulation over any weaknesses in the walls.

Protects the structure of your building

Another benefit of external wall insulation is that it improves the weatherproofing of your property, thereby protecting the structure from the elements. If condensation, damp, or mould can enter the property, then severe structural damage can occur, such as rot, which will come with a significant cost to repair.

Can be fitted with minimal interruption

Often, any sort of significant home improvement will be very disruptive to your home life and will require a lot of preparation before work can begin. Internal wall insulation, for example, will require you to move any radiators, plug sockets or other fixings in all the rooms that you want to install the insulation in, and then redecorate the walls. Installing external wall insulation, on the other hand, can be done with minimal interruption.

Can be used to improve the appearance of your home

If you’re looking to change the appearance of the exterior of your property and increase its thermal efficiency, you can achieve both by installing external wall insulation. The new outer wall can be made to match the existing walls or create an entirely new aesthetic with a range of finishes such as brick effects, pebble dash and mineral renders.


External wall insulation is a great choice for your home that will see you spending less on heating and possibly improving the value of your property as well. If you are interested in installing external wall insulation on your property, then please do get in touch and see how we can help.
