External Wall Insulation (EWI): Enhancing Thermal Performance, Energy Efficiency, and Aesthetics

At Emit Zero, we specialise in providing external wall insulation (EWI) installations that allow homeowners to improve the thermal performance of their properties while reducing energy consumption and updating the overall aesthetics. By fitting insulation to the exterior of a building, EWI offers numerous benefits, including improved comfort, lower energy bills, and a more attractive home exterior. 

This is an excellent solution for enhancing the thermal performance of solid walls which are typically constructed with interlocking bricks and a thickness of around 9 inches. Solid walls lack the additional layer of single-skin brickwork found in cavity walls, which allows for protection against external elements. As a result, solid walls are more prone to heat loss and susceptible to water penetration, leading to ongoing issues such as dampness and mould. 

EWI systems consist of multiple layers that work together to create a thermal barrier, reducing heat transfer and minimising moisture ingress. The insulation boards, tailored to specific project requirements, form the foundation of the system. Rest assured that all the products and systems we install hold BBA certifications, ensuring compliance with industry standards and regulations. 

Once the insulation boards are securely fixed to the wall, the EWI system is built up with additional layers, including:

•    Base coat

•    Reinforcement mesh
•    Primer
•    Top coat render in a wide range of unique colours

Since all the work takes place externally, there is no need for you or any of the occupants to vacate your home during the renovation.

External wall insulation offers a range of advantages for your home: 

Improved thermal efficiency

EWI enhances the thermal performance of your walls, reducing heat loss and improving indoor thermal comfort. This results in lower heating costs and reduced CO₂ pollution.

enhanced comfort

Heat loss through walls can lead to dampness, degraded paint and plaster, and the development of mould. Proper insulation limits condensation and tackles damp issues, creating a more comfortable living environment. Enjoy cooler summers and warmer winters.

increased property value

Investing in EWI enhances the long-term value of your property. Potential buyers are attracted to energy-efficient homes with low heating costs. A well-insulated and thermally efficient house offers a significant advantage in the real estate market.

reduced noise levels

Noise pollution has a negative impact on our comfort and well-being. EWI helps reduce disturbances from external noise sources, such as traffic, creating a quieter and more comfortable home. 

enhanced aesthetics

Adding EWI to your home not only improves its insulation but also provides an opportunity to rejuvenate its appearance. Choose from a variety of finishes to achieve a fresh, modern look.

With Emit Zero's EWI installation services, you can transform your home into a comfortable, energy-efficient, and visually appealing space. Our expertise in external wall insulation ensures a high-quality installation that delivers long-lasting benefits. Take the step towards improved comfort, reduced energy consumption, and enhanced property value by choosing Emit Zero as your trusted external wall insulation installer.

Answers to our most frequent questions

Which buildings are suitable for external wall insulation?

External wall insulation (EWI) is suitable for buildings with solid walls. If your house has cavity walls, there is no need for EWI as insulation can be injected into the space within the walls.

 How can I determine if I have solid walls?

To identify whether your walls are solid or cavity walls, examine the brick pattern on the exterior of your house. If all the bricks are rectangular and laid end-to-end, it is likely a cavity wall. However, if some of the bricks have their square end facing outward, it is probably a solid wall. 

Can EWI help prevent condensation?

EWI can indeed help prevent condensation. By trapping heat inside rooms, EWI prevents internal walls from becoming too cold. Cold walls attract moisture from the air, leading to condensation. EWI minimises this issue by maintaining warmer internal wall surfaces. 

How long does the installation process take?

The duration of EWI installation varies depending on the size of your property. Most installations are completed within 5 to 7 working days. However, the installation is weather-dependent, so occasionally, it may take longer during winter or adverse weather conditions.
