What Is External Wall Insulation?

External wall insulation involves applying a layer of insulation to the exterior walls of a property. At Solid Wall Insulation, we use materials like expanded polystyrene (EPS) and mineral wool to achieve superior thermal performance.

EPS is renowned for its excellent moisture resistance and insulation properties, while mineral wool offers great fire resistance and soundproofing. The process includes a weather-resistant finish to protect the building fabric; we typically use proprietary render systems compliant with BBA certification to ensure durability and adherence to industry standards.

This method is an ideal solution for homes with solid walls lacking cavity insulation, such as older properties and heritage buildings, reducing heat loss effectively. Proper installation can help cut energy bills and improve interior comfort.

How Much Does External Wall Insulation Cost?

External wall insulation typically costs between £100 and £150 per m². This pricing is influenced by factors such as the size and height of the walls, the type of insulation used, and the complexity of the installation.

The materials we use include expanded polystyrene (EPS) and mineral wool, each offering distinct benefits in thermal performance and moisture resistance. Labour costs also vary depending on accessibility and whether scaffolding is needed, which is common for multi-storey properties.

Additional features, such as decorative renders or finishes, can also affect the price. The installation process usually takes one to two weeks but can vary based on the property's size and weather conditions.

What Types of External Wall Insulation Are Available?

In , Solid Wall Insulation offers a variety of insulation options designed to enhance thermal efficiency and energy savings for residential and commercial properties:

Expanded Polystyrene (EPS): Lightweight and cost-effective, providing excellent thermal insulation. It is also moisture-resistant, making it suitable for damp climates.
Mineral Wool: Known for its fire resistance and soundproofing capabilities. Mineral Wool is also highly breathable, reducing condensation issues.
Phenolic Boards: Offer high insulation value with thinner layers, ideal for areas with space constraints. These boards have a low thermal conductivity, which maximises energy efficiency.

Our team uses specific installation techniques, such as adhesive and mechanical fixings, to ensure the longevity of your insulation. We can guide you in choosing the most suitable type for your property, taking into account your specific needs and local building regulations.

What Are the Benefits of External Wall Insulation?

External wall insulation offers numerous advantages, including:

Energy Savings: By reducing heat loss through walls, insulation can decrease energy consumption in homes. Typically made from materials such as expanded polystyrene (EPS) or mineral wool, these systems improve thermal resistance and can achieve U-values as low as 0.3 W/m²K, contributing significantly to lower energy bills.
Increased Comfort: Insulation helps stabilise indoor temperatures year-round by preventing heat from escaping in winter and entering in summer. This consistent thermal comfort is particularly beneficial for detached homes and older properties, which often have solid walls.
Weather Protection: It adds a protection layer to your home's exterior, shielding it from rain, wind, and temperature fluctuations. This can help prolong the lifespan of your building's structure, as well as prevent issues such as damp or mould.
Environmental Impact: By enhancing energy efficiency, external wall insulation reduces the carbon footprint of your home. Systems like those incorporating vapour-permeable membranes can also mitigate condensation issues while maintaining a breathable building envelope.

How Does External Wall Insulation Work?

To install external wall insulation, our process involves several key stages to ensure effectiveness and durability.

Initial Assessment: We begin by conducting a thorough assessment of the property to determine the most suitable insulation material. Options include expanded polystyrene (EPS), mineral wool, or phenolic foam, each providing different thermal performance metrics that meet specific U-values required by building regulations.
Wall Preparation: The wall surfaces are carefully cleaned to remove any debris, prior paint, or surface imperfections. This step might also involve repairing damaged areas and ensuring the surfaces are structurally sound.
Insulation Fixing: Insulation panels or boards are securely fixed to the walls using mechanical fixings and/or adhesive methods, depending on the wall structure and insulation material choice. We ensure alignment and proper coverage to avoid thermal bridging.
Rendering: A multi-layer render system is applied, consisting of a base coat with mesh reinforcement to provide strength and resilience. This is followed by final decorative and weather-resistant coats available in various textures and colours to enhance the property’s appearance.

Each step is executed with precision to ensure long-lasting insulation performance, improving your home's energy efficiency and reducing heating costs. Contact us to discuss how we can help insulate your property effectively.
