5 Reasons Why You Should Fit External Wall Insulation

Whatever the age of your property, it’s important to make sure it’s got sufficient insulation. Not only will this make your home more comfortable, it will also reduce your energy bills.

Installing external wall insulation involves fixing a layer of insulation material to your outside walls, then covering it with render or cladding. If you have solid external walls, it’s worth considering fitting it. Keep reading to find out 5 benefits of external wall insulation.

1. Improves your home energy efficiency

The main advantage to external wall insulation is that it can significantly improve the energy efficiency of your home. It will block up any cracks and gaps in your brickwork, which will reduce draughts. Plus, it will lower the amount of heat that escapes from your home through the walls, reducing your energy wastage and heating bill. According to the Energy Saving Trust, you could save between £100 and £450 every year.

2. Doesn’t reduce your living space

Another bonus to external wall insulation is that, unlike internal wall insulation, it doesn’t reduce your living space. External insulation only takes up outside space, which is much less valuable.

3. Increases your property lifetime

External wall insulation is also beneficial because it can increase your property lifetime. As it covers your brickwork it protects it from weathering and other damage, which can help your home to last longer.

4. Reduces condensation and damp

Another advantage to external wall insulation is that it can help to reduce condensation on your internal walls. It can also help to prevent damp – although not rising or penetration damp.

5. Improves sound resistance

External insulation is also a great addition to your home because it will improve its sound resistance. So if you live by a busy road or near an airport this could be very handy.

So there are plenty of reasons why it’s worth considering fitting external wall insulation. To find out about other types of solid wall insulation, see our article on internal wall insulation.
