External wall insulation (EWI) is the process of securing insulation boards to the outside walls of a building before applying a decorative render on top as a means of protection against the weather. It’s well known that EWI is great for saving money on your energy bills, however, have you stopped to consider the positive secondary effect of this?
Thoroughly insulating your home has two outcomes: less heat escapes through the walls and less energy is wasted to compensate for this. EWI is, therefore, a great way to reduce your carbon emissions. With better insulation and greater energy efficiency comes a reduction in the use of gas, oil or coal, which means that your overall carbon usage is lower.
Why do Fossil Fuels Harm the Environment?
Gas, oil and coal are fossil fuels, which means they are non-renewable energy sources. When burned, they release carbon dioxide gas (carbon emissions) into the environment, which contributes towards the greenhouse effect and increases global warming.
What is the Greenhouse Effect?
The greenhouse effect occurs when gases in the atmosphere, such as carbon dioxide, trap heat from the sun. This causes the Earth to warm up.
Human activities are changing the way that the Earth naturally traps heat due to the fact that we are constantly burning damaging fuels and releasing harmful gases (carbon dioxide) into the environment. The more we do this, the more the Earth’s temperature will increase; we’re already seeing the effect of this through rising sea levels, the steady extinction of certain species and damage to the coral reef caused by warmer waters.
The situation is urgent, yet not many people know how to make small, positive changes.
Going Green with EWI
On a yearly basis, external wall insulation can save a detached property 1870kg CO2. If every home in the UK was insulated to this standard, think about the reduction in carbon emissions and the positive effect this would have on the environment.
