What is External Wall Insulation (EWI)?

External Wall Insulation, commonly known as EWI, is a system used to improve the thermal performance of a building by installing insulation to the outside of its external walls.

Rather than insulating the property from inside, insulation boards are securely fitted to the external walls before being covered with a reinforced base coat and protective render system. The system is completed with a thin coat silicone render, providing a smart contemporary appearance as well as an important protective finish.

This means one project can both improve the insulation of your property and transform its external appearance.

How Does External Wall Insulation Work?

A typical EWI installation involves several carefully completed stages.

The existing walls are first assessed and prepared to provide a suitable surface for the insulation system. External insulation boards are then installed and mechanically fixed as required by the specified system.

A reinforced base coat and mesh are applied over the insulation, helping to create a strong and stable surface.

The final stage is the application of the thin coat silicone render.

The precise specification will depend on the construction and condition of the property and the EWI system being used. M Coatings can assess your building and advise on an appropriate solution before work begins.

Why Choose EWI for Your Property?

External Wall Insulation can be particularly useful for properties where improving the thermal performance of the existing external walls is required.

Depending on the building and the system specified, the advantages can include:

  • Improved thermal performance of external walls
  • Reduced heat loss through the building fabric
  • Improved comfort within the property
  • An opportunity to upgrade older properties
  • No loss of internal floor space from insulating the inside of external walls
  • Additional protection for the external wall structure
  • A complete transformation of tired or unattractive exterior walls
  • A modern rendered finish in a choice of colours
  • Insulation and exterior refurbishment completed as part of the same project

Because the insulation is fitted externally, EWI can be an especially attractive option when you want to improve a property's insulation without reducing the dimensions of rooms inside.

Thin Coat Silicone Rendering

The quality of an External Wall Insulation installation isn't only about what goes underneath the surface. The final render plays an important role in both protecting the system and determining how the completed property looks.

We can finish External Wall Insulation systems with thin coat silicone render.

Thin coat silicone render provides an attractive modern finish while offering excellent resistance to the British weather. It is flexible, water repellent and available in a variety of colours, allowing the exterior of a property to be completely updated as part of the insulation work.

Unlike traditional painted render, a coloured silicone render can provide the finished colour as part of the render system itself, helping to create a clean, consistent appearance.

The result is an insulated property with a professionally rendered exterior that can look dramatically different from the original building.

EWI and Silicone Rendering for Older Properties

Many older properties were constructed before today's expectations for thermal insulation.

Depending on their age and construction, some homes can be difficult to improve using conventional cavity wall insulation. External Wall Insulation may provide an alternative because the insulation is installed on the outside of the existing walls.

Every property is different, however, and it is important that the proposed insulation and render system is suitable for the building.

We combine extensive experience of plastering, rendering, wall coatings and insulation, enabling us to look at the exterior of the building as a complete system rather than simply applying a new surface finish.

External Wall Insulation for Home Renovations

EWI can also be worth considering when carrying out a wider renovation or exterior refurbishment.

If scaffolding is already required and you are planning to re-render the property, it can be an ideal opportunity to investigate whether the thermal performance of the external walls could be improved at the same time.

Instead of simply changing the appearance of the building, External Wall Insulation allows you to consider what's happening beneath the new render too. Our expert render and plasterers in Surrey and London can advise you on the options available and provide a professional finish using thin coat silicone render.

EWI for Extensions and New Building Work

External insulation systems can also be incorporated into suitable extensions, renovations and other building projects.

Using a consistent render finish can help visually bring together different sections of a property, particularly where an extension has been constructed using different materials from the original building.

A coloured thin coat silicone render can create a clean, uniform exterior while the insulation system beneath contributes to the required thermal performance of the walls.

External Wall Insulation FAQs

We specialise in finishing EWI systems with thin coat silicone render, providing an attractive, durable and weather-resistant external finish.

Yes. Because the insulation is installed externally and subsequently rendered, EWI can significantly change and improve the appearance of a property. There's a choice of render colours, which we can offer you, allowing you to select a finish appropriate to your home.

External Wall Insulation can be fine for older houses, particularly for properties where other forms of wall insulation may not be appropriate. However, the construction and condition of the building needs to be assessed before deciding on the correct insulation and render system. We can help you with this too.

Yes. The render forms part of the finished EWI system. Once the insulation and reinforced base layers have been correctly installed, we then complete the exterior using the thin coat silicone render.

Silicone render is highly water repellent and helps protect the external surface against the weather while remaining suitable for use as part of a correctly specified external wall system.
