If you’re trying to enhance the energy efficiency and comfort of your home, selecting the right type of wall insulation is crucial. In addition to internal wall insulation, you may have the option to install external wall insulation and this could be a better option for your property. Choosing between these two options can be a difficult decision, as each has unique benefits and considerations. In this post, we have listed some key factors to consider when investing in new insulation materials, helping you determine whether internal or external wall insulation systems are more suitable for your needs.

Type of Property and Structural Constraints

The type of property you own will play a significant role in determining the most suitable insulation method. Internal insulation is often preferred for historical properties and listed buildings due to restrictions on altering external appearances. Installing insulation inside the home will help to preserve the historic facade while still improving energy efficiency. On the contrary, modern properties with smaller rooms could benefit from external wall insulation systems. They won’t take up precious space inside the home when improving energy efficiency.

Budget and Cost Implications

For many homeowners, the cost of the insulation project is a major factor in the decision-making process. Generally speaking, external wall insulation systems are more expensive upfront due to the materials and the scale of the work involved. However, since this investment also provides an opportunity to improve the exterior of a property, it can improve things like weather resistance and durability. It’s key to note that while external wall insulation can be most costly initially, it can offer greater energy savings over time. By significantly reducing heat loss, this type of insulation can reduce utility costs and provide a better return on investment over time.

Installation and Disruption

It’s beneficial to consider how the installation process will impact your daily life. Installing internal insulation can be disruptive as it involves work inside your home, potentially affecting your main living spaces during installation. However, it can be a more suitable choice if you are keen to maintain the current exterior of your property. On the other hand, external wall insulation systems are less disruptive to your day-to-day life as they only require access to the exterior of your property. Yet, this can be challenging in certain settings, like attached homes.

Aesthetic Impact

The appearance of your property post-installation is an important consideration. External insulation can significantly alter the external look of your property, yet it also offers the opportunity to improve and modernise the facade. This can potentially enhance the curb appeal and value of your home. While internal insulation doesn’t impact the exterior appearance of your home, it does slightly reduce the internal dimensions of your rooms. This is a critical factor to consider in smaller spaces where layouts can be impacted by room size.

Energy Efficiency and Performance

It’s important to assess the energy efficiency benefits of each type of installation. Typically, external wall insulation provides superior thermal performance by reducing thermal bridging and enhancing overall energy efficiency. This makes it a popular choice for homeowners searching for comprehensive energy-saving measures. However, internal insulation can also improve energy efficiency and reduce the cost of your energy bills over time. It’s key to note that the insulation material and thickness you choose will have a direct impact on performance, not just where the installation is installed.

Longevity and Maintenance

The durability and maintenance requirements of the insulation system are also key factors to take into account. Most external wall insulation systems are designed to withstand the elements, making them a durable choice. However, they may require ongoing maintenance to the external finish over time, which should be factored into long-term upkeep costs. Internal insulation is less exposed to weathering, but the quality of the installation is crucial to prevent common issues like damp and mould. Proper ventilation, particularly in rooms like the bathroom and kitchen, is essential to ensure the insulation stands the test of time.

Installing Wall Insulation Systems 

Both internal and external wall insulation systems have their unique advantages and considerations. External wall insulation systems offer excellent energy efficiency and aesthetic improvements but come at a higher cost and may require planning permissions. Internal insulation is more cost-effective and less disruptive to the property’s exterior but can reduce interior space and impact longevity if not installed correctly.Ultimately, the choice depends on your specific circumstances. Whichever option you choose, investing in proper insulation is a step towards a more energy-efficient, comfortable and sustainable living environment.
