What is Insulated Render? Understanding the Basics of EWI
Insulated rendering, also known as External Wall Insulation (EWI), is an innovative rendering system that combines thermal insulation with a protective and decorative exterior finish. By fixing a layer of insulation material to the external walls of a property and covering it with a specially formulated render, insulated render improves energy efficiency, reduces heat loss, and enhances weather protection.
The insulation layer, typically made from materials such as expanded polystyrene (EPS), mineral wool, or phenolic foam, creates a thermal barrier that minimises heat transfer between the interior and exterior of the property. This helps to maintain a more stable and comfortable indoor temperature while reducing energy consumption and costs.
In addition to its thermal properties, insulated render provides a durable, weather-resistant, and breathable layer that prevents moisture penetration and minimises the risk of cracks, chips, or other damage. This protective layer enhances the longevity of the building’s exterior and reduces maintenance requirements over time.
EWI systems can be applied to a wide range of property types, including new builds and existing structures, and are suitable for various substrates such as brick, concrete, or masonry. Insulated render also offers design flexibility, with a wide array of colours, textures, and finishes available to complement the architectural style of the building and enhance its overall appearance.

3 Major Benefits of Insulated Rendering (EWI)
When choosing insulated rendering as the rendering solution for your UK home, you can expect many benefits with the 3 biggest benefits stated below:
Energy Savings & Lower Bills
Insulated render can help homeowners save up to 35% on their energy bills by minimising heat loss and maintaining a stable indoor temperature. This increased energy efficiency reduces reliance on heating and cooling systems, leading to substantial savings on utility costs and a lower carbon footprint.
Enhanced Comfort and Weather Protection
Insulated render enhances comfort by eliminating cold spots and drafts, creating a consistent indoor temperature. The durable, weather-resistant render layer also protects against moisture, cracks, and damage, extending the lifespan of your property’s exterior and reducing maintenance requirements.
Improved Aesthetics and Property Value
Insulated render offers a wide range of design possibilities, with various colors, textures, and finishes to suit your taste and property style. This versatility allows you to transform your home’s exterior, boosting its curb appeal and increasing its perceived and actual market value.
How thick is an insulated render system?
The thickness of an insulated render system is a key factor in determining its thermal performance. The overall thickness varies based on the insulation material and the desired level of energy efficiency.
An insulated render system consists of an insulation layer fixed to the external walls and render layers applied on top. The insulation layer, typically ranging from 100mm to 200mm thick, plays a crucial role in reducing heat loss. Common insulation materials include expanded polystyrene (EPS) and mineral wool, with EPS layers ranging from 90mm to 190mm and mineral wool layers between 110mm and 210mm thick.
The render layers, providing a protective and decorative finish, are much thinner, with a combined thickness of around 20-30mm.
The total thickness of an insulated render system usually falls between 120mm and 230mm.

Frequently Asked Questions About Insulated Render (EWI)
Yes, insulating render (EWI) is an excellent choice for improving your home’s energy efficiency, comfort, and appearance. It offers significant benefits, such as reduced energy bills, enhanced weather protection, and improved aesthetics, making it a worthwhile investment for UK homeowners.
Insulated render, also known as External Wall Insulation (EWI), is a system that combines a layer of insulation material fixed to the outer walls of a property with a protective and decorative render finish. This system improves thermal insulation and reduces heat loss – optimising homes to keep them cool during the summer and warm throughout the winter.
The best render for insulation depends on various factors, such as the type of insulation material, the property’s substrate, and the desired finish. At City Rendering, we use high-quality, industry-leading insulated render systems tailored to each project’s specific requirements to ensure optimal performance, durability, and aesthetic appeal.
Yes, thermal render, also known as insulated render or EWI, is available and offers an effective solution for improving a property’s thermal insulation. City Rendering specialises in providing top-quality thermal render systems that enhance energy efficiency for homes across the UK.
While it is possible to paint insulated render, it is generally not necessary, as the render itself is available in a wide range of colours and finishes. At City Rendering, we offer a variety of insulated render options that can be customised to suit your aesthetic preferences, eliminating the need for additional painting.
The main downsides of EWI include the initial installation cost and the potential for a slight reduction in the property’s overall footprint due to the added thickness of the insulation layer. However, the long-term energy savings, improved comfort, and increased property value often outweigh these drawbacks, making EWI a smart investment for most homeowners.
While traditional rendering alone does not provide significant insulation, insulated render/external wall insulation (EWI) is specifically designed to improve a property’s thermal insulation. By combining a layer of insulation material with a protective render finish, EWI effectively reduces heat loss, enhances energy efficiency, and creates a more comfortable living environment.
