External Wall Insulation Bristol
What is external wall insulation?
External wall insulation (EWI), also commonly referred to as solid wall insulation and insulated render, is a highly effective way of improving the thermal efficiency of buildings, reducing energy bills and overall comfort of living spaces.
EWI involves adding insulation to the exterior of a building to create a barrier against heat loss. The insulated material is then coated in a render or cladding system, which provides a protective and waterproof layer while enhancing the aesthetic of the property.

What are the Benefits of External Solid Wall Insulation?
There are many benefits of having your solid walls insulated at your property. Some of these include:
- Up to 33% of heat energy escapes uninsulated cavity walls, so you can expect to make massive savings on your heating bills.
- As you will be using less energy to heat your home, you will reduce your carbon footprint as you are decreasing carbon emissions.
- Your property value will increase, making you a higher return on your property if you ever come to sell.
- As the insulating material will act as a noise barrier, preventing sound waves from passing through, you can expect less outside noise to disturb you in your home.
- Insulating the exterior of your home won’t reduce the internal floor area like internal wall insulation would.
- The insulation and render will protect existing walls as they will act as a barrier from harsh weather conditions.
- EWI will make your home more comfortable and cosy due to the increase in thermal efficiency
- Solid wall insulation not only keeps your home warmer in the winter but also cooler in the summer, making the building a more comfortable living space year-round.
External Insulated Render FAQs
While external wall insulation is what it’s typically referred to as, there are other common names for EWI too. Some of these include exterior wall insulation, insulated rendering, and solid wall insulation. While EWI may have various names, they all refer to the application of insulation and render to the exterior of a property to improve thermal efficiency.
A layer of insulation material is fixed to the external walls of a property, which is then coated in a layer of render or cladding. The insulation stops heat from escaping your home, acting as a thermal barrier. This drastically increases the thermal efficiency of a property, keeping the building warmer in winter and cooler in summer.
External wall insulation can be made from various materials, with each material having its own benefit, budget and insulation requirements. The most common include expanded polystyrene (EPS), which is lightweight, cost-effective and the most commonly used EWI system. Mineral wool is also commonly used in larger buildings such as flats and apartments as it carries excellent fire-resistant properties due to being non-combustible.
Because insulated rendering is considered ‘permitted development’, it doesn’t typically require planning permission to start the work. That being said, if the thickness of EWI would interfere with somebody’s land or property, your home is a listed building, or your local authority doesn’t allow special colours in your area, you may require planning permission for EWI.
