How does External Wall Insulation Work?
External Wall Insulation improves your home’s energy efficiency by adding insulation to the exterior walls – think of it like a big blanket for your home. EWI is an energy saving method that improves thermal efficiency, reducing energy costs and can give homes a refreshed, new look.
An EWI system consists of several layers in order for it to perform effectively. These layers are the insulation board itself as well as the render, reinforcement mesh, primer and the top coat render.
A real positive of EWI is that all the work we have to do takes place outside of the home, so there is no need to move furniture around, worry about people coming in and out of the property or worry about the plumbing and electrics being affected.
What Are The Benefits of External Wall Insulation?
External Wall Insulation (EWI) brings several benefits to residents. Some of the main advantages are:
Improved thermal performance: By enhancing the walls’ ability to retain heat, EWI keeps indoor temperatures higher while lowering heating costs, and helps cut carbon dioxide emissions in the process, which in turn makes a property more energy efficient.
Increased comfort of your living space: A well-insulated home also creates comfort. Heat escaping through uninsulated walls can lead to them becoming damp, damaging paint, plaster, and wallpaper, and in some cases, contribute to mould growth. Damp can even affect respiratory health. External Wall Insulation limits the heat escaping through walls, limiting condensation and possible damp issues, all while keeping the home warmer in winter and cooler in summer. This means year round comfort.
Reduced Noise Levels: EWI reduces noise levels, creating a quieter and more peaceful living space. EWI acts as a buffer between external sounds such as traffic and the inside of a home, meaning residents can enjoy the warmth alongside some peace and quiet.
Aesthetically Pleasing: In addition to the practical benefits, EWI can truly refresh the appearance of a property. With ArtBrick, we can revitalise your stock with new brickwork in the same style, or give the home a complete facelift.


Available to More Homes Than Ever Before
Traditionally, Westdale Midlands has specialised in improving social housing properties, but we are now extending our services to private homeowners too.
Homeowners, regardless of whether they’re working or receive benefits, funding may be available to help cover the cost of insulation improvements. Eligibility depends on the property and the criteria set by the funding providers. For example, some schemes are designed to make homes “retrofit ready” by financing essential energy upgrades such as EWI.
This means more households can now benefit from the energy savings, comfort, and improved appearance that come with External Wall Insulation.
