Comparing Internal & External Insulation

When your walls lack a cavity, External Wall Insulation (EWI) is often the best choice. For solid walls, you have two main options to consider:

Internal Wall Insulation: This method involves applying insulation to the inner surface of exterior walls. While generally more cost-effective, it does come with its own set of limitations, such as reducing the usable interior space and requiring alterations to fixtures and fittings.

External Wall Insulation: This process entails adding insulation to the exterior of existing walls, typically finishing with render or another form of cladding for weather protection. EWI is less disruptive to the interior of your home and can enhance the building’s external appearance.

Benefits Of Insulation

External wall insulation is an excellent solution for improving the thermal efficiency of homes with solid walls. It not only boosts energy efficiency but also enhances the overall comfort and sustainability of your living space. Properly insulating your walls can create a more pleasant indoor environment by reducing drafts and maintaining a more consistent temperature throughout the year. Additionally, it significantly cuts down on energy consumption, leading to lower utility bills and a smaller carbon footprint. Investing in EWI can ultimately provide long-term financial savings and contribute to a more sustainable lifestyle.

External Insulation Costs

When planning for external wall insulation, it’s crucial to understand the expenses involved, which vary based on property type and size. For example, insulating a three-bedroom semi-detached house typically costs between £5,000 and £9,000. In contrast, larger standalone homes may require a more extensive insulation process, with costs ranging from £8,000 to £15,000.

In addition to the primary insulation costs, homeowners should also consider potential additional expenses. These may include the need to lift or replace pipes and wires to accommodate the insulation installation, which can increase the overall project cost.

Despite these expenses, investing in external wall insulation offers significant benefits. By prioritising insulation, homeowners can create a more comfortable living environment, achieve long-term energy savings, and reduce their carbon footprint. This balanced approach not only enhances the thermal efficiency of the home but also contributes to financial savings and environmental sustainability.

Floor Space Loss

Internal insulation involves adding layers to the inner surface of exterior walls, including a wood frame, rigid foam insulation, a vapour barrier, and plasterboard. Over time, this buildup can reduce floor space by 100–150 mm, posing challenges, particularly in smaller rooms. Despite this, it remains a viable option for enhancing thermal efficiency in older properties.

Cold Bridging

Insulation outside the home reduces the risk of cold bridges. The insulation acts as a shield, preventing cold air from reaching the stone walls. It’s like wrapping your house in a coat, covering everything effectively. This method ensures that all parts of your home are uniformly protected against the elements.

Weak Spots

Masonry construction conducts heat efficiently, allowing cold air to infiltrate, leading to discomfort. Minimising cold bridging addresses these weak points, keeping warmth in and cold out, enhancing comfort and energy efficiency. By targeting these vulnerable areas, external wall insulation creates a more stable and pleasant indoor environment.
