Cavity wall insulation is one of the most efficient and affordable ways to improve the energy efficiency of homes in Ireland. It’s particularly suited to homes built with a cavity between the internal and external walls and can be installed in properties from various construction periods using a range of materials.
The cost of cavity wall insulation typically ranges from €8.50 to €13 per m², but this varies depending on factors such as the type of material used and the size of the property. For many homeowners, the investment pays off in the form of lower energy bills, enhanced comfort, and an increase in property value.
In this article, we’ll figure out the costs, benefits, and key considerations to help you determine if cavity wall insulation is the right choice for your home in Ireland.
What is Cavity Wall Insulation?
Cavity wall insulation involves filling the gap between a building’s inner and outer walls with insulation material. This process significantly improves the home’s ability to retain heat, reducing energy consumption and lowering heating costs.
There are different materials that can be used for insulation, such as:
- Blown mineral fibre
- Polystyrene beads
- Slow pour foam
Each of these materials has its own advantages in terms of cost, insulation performance, and suitability for different types of homes. The price of cavity wall insulation generally falls between €8.50 and €13 per m², but this can vary depending on the insulation material chosen.
Cavity Wall Insulation Costs in Ireland
The cost of pumped cavity wall insulation in Ireland typically ranges from €8.50 to €13 per m², depending on several factors. These include:
- The construction period of the home: Older homes, especially those built before 1978, often require more extensive work.
- Insulation material: The type of insulation material used can significantly influence the price.
- Cavity size: The larger the cavity, the more insulation material is required, increasing the cost.
- Location: Travel expenses and the availability of local contractors can affect pricing.
Typical Costs of Cavity Wall Insulation for Different Property Types
- 2-Bed Semi-Detached: €1,500 – €1,800

Factors Influencing the Cost of Cavity Wall Insulation
Several key factors can impact the final cost of your cavity wall insulation project:
- Age of the home: Homes built before 1978 may require more extensive work, which can drive up costs.
- Location: Costs may be higher in rural or remote areas due to increased travel and logistical expenses.
- Insulation material: Different materials come with varying costs, so the choice of material will affect the total price.
- Cavity size: Larger wall cavities need more insulation, which can increase the total project cost.
How to Know if Your Home is Suitable for Cavity Wall Insulation?
Several factors can help you determine whether your home is suitable for cavity wall insulation. These include:
- Visual inspection: Look for external signs of cavities in the brickwork or construction type.
- Measuring wall thickness: Typically, a cavity wall will be around 25 cm thick.
- Consulting an energy expert: A professional energy assessor or contractor can provide advice on whether your home is suitable for insulation.
- Using thermal imaging: This advanced technology can pinpoint areas where heat loss is occurring, helping you decide where insulation is needed.
Key Benefits of Cavity Wall Insulation
There are several benefits of cavity wall insulation that make it an attractive option for homeowners:
- Enhanced energy efficiency: Insulation reduces heat loss, meaning your home stays warmer for longer without needing as much energy for heating.
- Improved indoor comfort: With better insulation, your home will maintain a more consistent and comfortable temperature year-round.
- Reduced carbon footprint: By using less energy, you help reduce your home’s impact on the environment.
- Increased property value: Energy-efficient homes are in high demand, which can increase your home’s resale value.
- Noise reduction: Insulation can also help block out external noise, making your home quieter.
- Greater durability: Quality insulation can improve the longevity of your home by preventing issues related to moisture and temperature fluctuations.
Common Concerns and Potential Issues with Cavity Wall Insulation
While cavity wall insulation offers numerous benefits, there are some potential concerns to keep in mind:
- Water damage: Improperly installed insulation can lead to water ingress and structural damage, so ensure proper waterproofing is in place.
- Installation mistakes: Poorly installed insulation may not perform as expected, leading to reduced energy savings. Always use a qualified contractor.
- Low-quality materials: Using substandard insulation materials can result in poor long-term performance, so it’s crucial to choose high-quality products.
- Poor ventilation: Insulation can reduce airflow, which may cause condensation or dampness. Make sure your home is adequately ventilated to prevent this issue.
By addressing these concerns with proper planning and expert advice, you can ensure your insulation project delivers the best results.
Best Insulation Materials for Cavity Walls
There are several popular insulation materials for cavity walls, each with its own benefits:
- Blown mineral fibre: This material is known for its fire resistance and quick installation process.
- Polystyrene beads: A cost-effective option that works well in smaller spaces and offers good insulation properties.
- Slow pour foam: Ideal for larger cavities, this material provides excellent thermal insulation but is generally more expensive.
Consulting with an energy expert or contractor is essential to ensure you choose the best material for your specific property.
