External Wall Insulation
Our expert team provides comprehensive surveys to assess your property’s suitability for external wall insulation, ensuring you receive tailored solutions that not only reduce your energy bills but also improve your comfort and environmental impact.
What is External Wall Insulation?
External wall insulation (EWI) involves applying a layer of insulating material to the exterior walls of a building, which is then covered with a protective render or cladding.
This method is particularly beneficial for buildings with solid walls, as these types of walls typically have poorer thermal performance compared to cavity walls. EWI improves a building’s thermal efficiency by reducing heat loss, which can significantly decrease energy bills.
The insulating material used can vary, but commonly includes materials such as expanded polystyrene (EPS), mineral wool, or phenolic boards. These materials are chosen for their excellent thermal properties and durability.
The process of installing EWI begins with a thorough assessment of the existing walls to ensure they are suitable for insulation. Once any necessary repairs are made, the insulation boards are fixed to the walls using adhesive and mechanical fixings.
A base coat with reinforcing mesh is then applied to provide stability and protection, followed by a decorative finish. This not only enhances the energy efficiency of the building but also improves its aesthetic appeal.
Frequently Asked Questions
External wall insulation (EWI) involves adding a layer of insulation material to the exterior walls of your building. This is then covered with a protective render or cladding. EWI helps to reduce heat loss, enhance thermal efficiency, and improve the overall aesthetic of your property.
EWI works by creating a thermal barrier on the outside of your building. The insulation material prevents heat from escaping through the walls, maintaining a consistent indoor temperature and reducing the need for excessive heating or cooling.
Common materials used for EWI include expanded polystyrene (EPS), mineral wool, and phenolic boards. Each material has unique properties, and the best choice depends on your specific needs and the characteristics of your property.
Yes, EWI can significantly improve the appearance of your property. The insulation is covered with a render or cladding, which can be finished in a variety of textures and colours, giving your home a fresh, modern look.
The installation time for EWI varies depending on the size and condition of your property. Typically, it can take anywhere from a few days to a few weeks. Our team will provide a detailed timeline during the survey.
Why You Should Have External Wall Insulation
There are numerous benefits to installing external wall insulation, making it a wise investment for homeowners and property managers. First and foremost, EWI can dramatically reduce your heating costs by preventing heat from escaping through the walls. This is particularly important in older buildings with solid walls, where heat loss can be a significant issue. By improving thermal efficiency, EWI helps maintain a more consistent and comfortable indoor temperature, reducing the need for excessive heating in winter and cooling in summer.
In addition to energy savings, EWI contributes to reducing carbon emissions, supporting environmental sustainability. As energy consumption decreases, so does the carbon footprint of your home, helping to combat climate change. Furthermore, EWI can enhance the structural integrity of your building by protecting it from weather-related damage. The insulation layer acts as a barrier against rain, wind, and frost, which can deteriorate the external walls over time.
Another compelling reason to consider EWI is the potential increase in property value. Improved energy efficiency and a modernised exterior can make your property more attractive to potential buyers. Moreover, the aesthetic enhancement provided by the new render or cladding can give your home a fresh and updated appearance, contributing to better curb appeal.
