Are you looking for ways to improve the energy efficiency and comfort of your home? If so, you might want to consider installing floor insulation. Floor insulation is a type of insulation that is applied to the underside or the top of the floor, depending on the structure and design of your house.

Floor insulation can help you reduce heat loss, lower your energy bills, and create a more pleasant indoor environment. But how much does floor insulation cost in Ireland? And what factors affect the price of floor insulation?

In this blog, you will get answers to these questions and more, so you can decide whether floor insulation is right for you.

What are the Types of Floor Insulation With Their Costs?

There are different types of floor insulation available, depending on the structure and design of your floor. The most common types of floor insulation are:

Suspended timber floor insulation

Suspended timber floor insulation is suitable for houses with a suspended timber floor, which is a floor that is raised above the ground and supported by wooden joists. The average cost for suspended timber floor insulation is about €105 per square metre.

Suspended timber floor insulation is applied to the underside of the floor, between the joists, and can be made of various materials, such as mineral wool, rigid foam, or sheep’s wool. Suspended timber floor insulation can improve the thermal performance and the acoustic performance of your floor, as it can reduce noise transmission between rooms.

Solid floor insulation

Solid floor insulation is suitable for houses with a solid floor, which is a floor that is in direct contact with the ground and made of concrete or stone. The average cost for solid floor insulation is about €30 per square metre.

Solid floor insulation is applied to the top of the floor, either above or below a screed layer, and can be made of materials such as expanded polystyrene (EPS), extruded polystyrene (XPS), or polyisocyanurate (PIR). Solid floor insulation can increase the thermal mass and the moisture resistance of your floor, as it can prevent dampness and condensation from occurring.

Floating floor insulation

Floating floor insulation is suitable for houses with a floating floor, which is a floor that is not fixed to the subfloor and can be lifted or removed easily. Floating floor insulation is applied to the top of the subfloor under a layer of flooring material, such as laminate, wood, or carpet. The average cost for floating floor insulation is about €20 per square metre.

Floating floor insulation can be made of materials such as cork, wood fibre, or rubber. Floating floor insulation can enhance the comfort and durability of your floor, as it can provide cushioning and protection from wear and tear.

How Much Does Floor Insulation Cost in Ireland?

The cost of floor insulation in Ireland depends on several factors, such as the type and size of your floor, the type and quality of the insulation material, the labour and installation costs, and the availability of grants or incentives.

However, as a general guide, you can expect to pay between €20 and €50 per square metre for floor insulation in Ireland. This means that for an average house with a floor area of 100 square metres, the total cost of floor insulation could range from €2,000 to €5,000. Of course, this is only an estimate, and the actual cost of floor insulation may vary depending on your specific situation and requirements.

Floor insulation is a type of insulation that is applied to the underside or the top of the floor, depending on the structure and design of your house. Floor insulation can help you reduce heat loss, lower your energy bills, and create a more pleasant indoor environment.

The cost of floor insulation in Ireland depends on several factors, such as:

The type of floor that you have

Different types of floors require different types of insulation, and some may be more expensive or difficult to install than others. For example, suspended timber floors can be insulated with mineral wool, rigid foam, or sheep’s wool, which are relatively cheap and easy to install between the joists.

However, solid floors, such as concrete or stone, may need to be insulated with expanded polystyrene (EPS), extruded polystyrene (XPS), or polyisocyanurate (PIR), which are more costly and may require removing the existing floor or adding a screed layer on top .

The size of the area that you want to insulate

The larger the area that you want to insulate, the more material and labour you will need, and the higher the cost will be. The average floor area of a house in Ireland is about 100 square metres, but this can vary depending on the type and design of your house. You can measure the floor area yourself or ask a professional to do it for you to get an accurate estimate of the cost of floor insulation.

The R-value of the insulation material

The R-value is a measure of how well the insulation material can resist heat flow, and the higher the R-value, the better the insulation performance. However, higher R-value insulation materials can more expensive than lower R-value ones, so you need to balance the cost and the benefit of choosing the right insulation material for your floor.

The recommended R-value for floor insulation in Ireland is between 2.5 and 3.5, depending on the type of floor and the climate zone.

The labour and installation costs

The labour and installation costs of floor insulation depend on the complexity and duration of the project, as well as the skill and experience of the installer. Some types of floor insulation, such as fibreglass batt or foam board, can be installed by DIYers, which can save you some money on labour costs.

However, other types of floor insulation, such as spray foam or solid floor insulation, may require professional installation, which can increase the cost significantly. The average labour cost for floor insulation in Ireland is between €20 and €50 per square metre, depending on the type of insulation and the installer .

The availability of grants or incentives

You may be able to reduce the cost of floor insulation by applying for grants or incentives that are available for energy efficiency improvements in Ireland, such as the Home Energy Grant from the Sustainable Energy Authority of Ireland (SEAI). The Home Energy Grant can cover up to 30% of the cost of floor insulation, depending on the type of insulation and the energy rating of your house. You can check the eligibility criteria and the application process or ask your installer to help you with it.

Conclusion

Floor insulation in Ireland is a strategic investment for homeowners, enhancing energy efficiency and indoor comfort. Factors like floor type, insulation material quality, and installation complexity typically affect the cost, which ranges from €20 to €50 per square metre.

Factors such as the insulation’s R-value and labour costs also play a crucial role in determining the overall expense. Despite the initial cost, the long-term benefits, including significant energy savings and a more comfortable living environment, justify this investment.

Additionally, homeowners can offset costs through available grants, like the SEAI’s Home Energy Grant, making it an economically viable and environmentally friendly option for enhancing home comfort.
