External Wall Insulation, the perfect solution for homeowners looking to save money on their energy bills while also increasing the comfort and value of their home.
WHAT IS EXTERNAL WALL INSULATION?
External Wall Insulation is a type of render system usually installed on older properties with little or no insulation to improve its thermal performance. This type of system involves fixing a layer of insulation, usually EPS, to a property before rendering over it.
External Wall Insulation is a popular solution for homeowners who want to improve the energy efficiency of their homes without losing valuable living space to internal insulation. By insulating the exterior walls, External Wall Insulation can significantly reduce heat loss through the walls, resulting in lower energy bills and a more comfortable living environment.
In addition to the energy-saving benefits, External Wall Insulation can also improve the appearance of a building, as it is available in a variety of colours and finishes. This can be particularly useful for older or outdated buildings, as External Wall Insulation can give them a modern and updated look.

How external wall insulation can increase property value
With new regulations set to come in, home owners will need to meet a certain energy rating when they sell their properties. EWI helps massively towards this, not only giving it curb appeal and increasing energy efficiency but also increasing the value of your home, which is especially important for older properties.
When insulating your home, your energy consumption goes down, therefore your carbon footprint is reduced. With bills reduced and less energy consumed you will have a positive impact on the environment.
EXTERNAL SOLID WALL INSULATION
External Solid Wall Insulation is a type of insulation that is applied to the exterior walls of a building to improve its thermal performance. This type of insulation is particularly useful for buildings that have solid walls, as they tend to lose heat more quickly than buildings with cavity walls.
The insulation material is applied to the outside of the building’s walls, followed by a protective layer of render or cladding to shield the insulation from the elements. This helps to reduce heat loss through the walls, resulting in lower energy bills and a more comfortable living environment.
External Solid Wall Insulation also has aesthetic benefits, as it is available in a range of finishes and colours. This means that it can be used to update the appearance of an older or outdated building, giving it a fresh, modern look.
If you’re interested in improving the energy efficiency of your home and reducing your energy bills, External Solid Wall Insulation could be the perfect solution for you.

INSULATED RENDER SYSTEM
An Insulated Render System is a type of external wall insulation that involves fixing an insulation layer to the exterior walls of a building, followed by a protective layer of render. This system is designed to improve the thermal performance of a building by reducing heat loss through the walls, which can result in lower energy bills.
One of the main benefits of an Insulated Render System is its ability to provide long-lasting energy savings. The system can significantly reduce heat loss through the walls, which means that homeowners can enjoy a more comfortable living environment for many years to come.
In addition to the energy-saving benefits, an Insulated Render System can also help to reduce condensation and dampness within a building. The insulation layer helps to prevent moisture from penetrating the walls, which can lead to mould and mildew growth. This can be particularly beneficial for older or poorly ventilated buildings.

External Wall Insulation FAQ
What is External Wall Insulation?
External Wall Insulation (EWI) is a type of render system usually installed on older properties with little or no insulation to improve its thermal performance. This type of system involves fixing a layer of insulation, usually EPS, to a property before rendering over it.
What are the benefits of EWI?
It can significantly improve the thermal efficiency of a building, reducing heat loss and lowering energy bills. It can also improve the appearance of a building, increase its lifespan and protect it from weather damage.
Is External Wall Insulation suitable for all types of buildings?
It can be installed on most types of buildings, including homes, commercial buildings and public buildings. However, the suitability of EWI depends on the age and condition of the building, as well as the type of render or cladding system being used.
How long does External Wall Insulation take to install?
The time it takes to install depends on the size of the building and the complexity of the installation. A typical installation can take between two to four weeks to complete.
Will External Wall Insulation affect the appearance of a building?
It can actually improve the appearance of your building by giving it a fresh, new look. There are a range of finishes available, including smooth, textured and brick-effect finishes, so you can choose a finish that complements the existing look of your building.
What buildings can EWI be used on?
EWI is particularly effective on older solid wall properties. Even older properties built using lime mortar, need to breath and are not suitable for EWI. If unable to breathe, it can have detrimental effects on the property. We are always happy to advise on what we believe to be the best practice for your property but we suggest doing some research online to find what suits your needs best.
Is External Wall Insulation a messy process?
Installation can be a messy process, but our team will take all necessary steps to minimise any mess or disruption. We will ensure that the site is left clean and tidy once the installation is complete.
How long does External Wall Insulation last?
The manufactures estimate a life expectancy of an EWI silicone render system to be around 25 years. With regular cleaning and maintenance, there’s no reason why it couldn’t be longer. You’ll be sure to get your monies worth.
What materials are used?
The most common form of EWI is made up of EPS (expanded polystyrene insulation) it is manufactured using beads of foam within a mould. Heat or steam is applied directly to the beads, causing them to expand and fuse together.
Other forms include mineral wall systems and XPS boards. These are stuck and mechanically fixed before a high polymer base coat is applied with a fibre glass mesh embedded. This is then followed by the coloured silicone topcoat.
Is External Wall Insulation environmentally friendly?
Yes, it is environmentally friendly as it can significantly reduce the amount of energy used to heat a building, which in turn reduces carbon emissions. Additionally, some insulation materials used in EWI are made from recycled materials.
The cost of External Wall Insulation
Although the initial outlay of EWI is substantial, by helping reduce your bills each month and creating a better living environment all round, it will contribute towards reducing some of those costs.
To give you an idea of costs, the following house cost on average:
Terraced house £6,000+
Semi-detached house £10,000 +
Detached £13,000+
What are the benefits of EWI?
- Heating bills reduced
- Property value increased
- Soundproofing properties
- Minimal disruption to the property
- Warm in the winter, cooler in the summer
- Modern long lasting, low maintenance finish
- Damp, condensation and mould issues reduced
Guide to insulation thickness and U Values:
With varying thicknesses ranging from 20-200mm theres insulation to suit every elevation. The general consensus is that you struggle to get any benefit for anything below 50mm although we always push for more and look to use 90mm or more as this is what most current building regulations require. The price difference between 20mm and 90mm is negligible over the price of a whole house with the rest of the process and costs being the same. The labour is the same and the rest of the materials is the same and so to get the most for your money we always recommend going as thick as possible.
Other things to consider regarding EWI:
Window sill depths
If you’re having new windows installed, we always recommend getting the largest sills possible (usually 225mm) and having the windows set as far forward as possible. Not only does this leave the room for insulation it also lets the windows function properly such as drainage vents etc we also always recommend trickle vents to be installed on new windows to help with ventilation. If you intend on keeping your windows but the sills are not long enough we can offer solutions such as sill extensions.
Verge trims
Verge trims are a fantastic cost effective option when things such as roof linings are too shallow to accept insulation. These also work in other situations such as around coping stones. They also not only stop water getting behind the render they also direct water away from the render to help reduce chance of staining.
Pipework
we always recommend pipework to be changed by a qualified and competent plumber prior to work commencing. Boiler flues, waste and water pipes usually are not far enough off of the wall to insulate behind. Some companies will render them in but that’s not recommended. We advise everything to be bought off of the wall to allow no elbows/joints to be inside the wall in case problems occur down the line.
