Retrofitting is a fantastic way to improve buildings, including key things like energy efficiency and sustainability, acoustics, and comfort. Critically, it can make them better for occupants and the environment. However, it can be challenging to retrofit various properties, especially any with solid walls. We want to have a closer look at this here, then you can rely on us if you want to create a plan with leading architects in London.
The problem
Did you know that the idea of cavity walls dates back much further than many people think? It is Greco-Roman, so is actually thousands of years old. While it fell out of favour, it began a resurgence in the UK towards the end of the 19th century. By the 1920s and 30s it was a widespread practice.
Although it is common practice now, there are millions of pre 30s buildings in the UK with solid walls. Sadly, they generally have much lower thermal performance than those with cavity walls. They lose heat much faster and are also more vulnerable to thermal bridging. As a result, they are harder to heat and cool, meaning they have a bigger carbon footprint.
Unfortunately, it is difficult to improve the performance of solid walls. It’s relatively simple to insert insulation into cavity walls. However, that isn’t an option when there is no void. It’s why just a faction of solid wall buildings are insulated. There is a relatively easy way to do it though; EWI. If you’re looking at retrofitting, you need to consider it. We’d be happy to help, giving you the full support of leading architects in London.
How do to it?
External wall insulation (EWI) is the practice of installing insulation on the outside of walls. You then cover it with a finish to protect it and improve the aesthetics. This can be a better option for properties because it means there is no loss of internal floorspace or layout alterations. Plus, it is far less disruptive.
The benefits
EWI is a great choice for most solid wall buildings. Significantly, it can improve energy efficiency as much as internal insulation. It keeps heat on the inside, preventing it from rapidly escaping through the solid walls. At the same time, it can protect against solar gain, preventing external heat from quickly entering the property. Ultimately, it can improve thermal comfort and performance.
As an added bonus, EWI can also improve other factors. Notably, it can provide a level of noise insulation. This is ideal if properties are near busy roads. It can also improve the aesthetics, offering a choice of finishes such as render, brick slips, tiling, and cladding.
