External wall insulation (EWI) is a building process in which a layer of insulating material is applied to the exterior walls of a home or building, followed by a protective finish. This form of insulation offers numerous benefits, from better energy efficiency and improved comfort to potential financial savings on energy bills. As more people look to increase the energy efficiency of their homes, external wall insulation is quickly becoming one of the most sought-after home improvements.
Let’s break down the details of what external wall insulation is, the key benefits, and how you can choose the right solutions for your home.
Why Choose External Wall Insulation?
External wall insulation is a great option for homeowners looking to make their homes more energy-efficient. It can significantly reduce heat loss in colder months and minimize the need for artificial cooling during hotter months, which ultimately leads to lower energy bills. External insulation is particularly effective for homes that lack cavity walls or have solid brick construction, which are often harder to insulate with traditional methods.
In addition to the direct energy-saving benefits, external wall insulation also helps to improve the overall aesthetic appeal of a property. The application of insulation materials can give your home a fresh, modern look while also providing protection against the elements. As external wall insulation improves the thermal performance of a building, it also increases comfort by stabilizing indoor temperatures year-round.
External Wall Insulation Materials
One of the most critical aspects of external wall insulation is the type of material used. There are several insulation options, each with its own set of benefits. The most commonly used materials for external wall insulation include polystyrene, mineral wool, and polyurethane foam. Here, we will discuss these materials in greater detail, highlighting their individual strengths.
Polystyrene External Wall Insulation
Polystyrene is one of the most widely used materials for external wall insulation, thanks to its excellent thermal insulation properties. It is available in two forms: expanded polystyrene (EPS) and extruded polystyrene (XPS). EPS is the most commonly used form due to its cost-effectiveness and ease of installation. XPS offers better thermal performance and durability, making it ideal for homes that require superior insulation performance.
Polystyrene-based insulation is lightweight, water-resistant, and easy to handle during installation. It effectively reduces heat loss by creating a barrier against the cold while ensuring that the home remains cool in the summer. With its low environmental impact, polystyrene is also considered one of the most eco-friendly insulation materials available.
Mineral Wool Insulation
Mineral wool insulation, made from rock or slag, is another popular option for external wall insulation. Known for its excellent fire-resistant properties, mineral wool is highly effective in preventing heat loss while also providing enhanced protection against fire. It also offers superior soundproofing capabilities, making it an ideal choice for homes located in noisy environments.
Mineral wool is also a more environmentally friendly option compared to other insulation materials because it is made from natural, non-toxic materials. It provides a high level of insulation while being resistant to moisture and mold, ensuring long-lasting performance in even the harshest weather conditions.
Polyurethane Foam Insulation
Polyurethane foam is a high-performance insulation material often used in external wall insulation applications. Known for its superior thermal insulation properties, polyurethane foam can significantly reduce heat loss and increase energy efficiency. It provides a seamless barrier that prevents the escape of heat and moisture, which makes it an ideal choice for homes located in regions with extreme temperatures.
Polyurethane foam also boasts a high insulation value per inch of thickness, meaning that a thinner layer can be used compared to other materials while still achieving the same level of insulation. This can be a significant advantage in homes where space is limited or where a thinner layer of insulation is required.
Benefits of External Wall Insulation
There are numerous advantages to investing in external wall insulation for your home or property. The key benefits include energy efficiency, increased property value, reduced maintenance costs, and enhanced indoor comfort. Below, we’ll dive into these benefits in more detail.
