Are you looking for the best way to keep your home warm, comfortable, and energy-efficient? If so, you might be thinking about what the most common insulation is in Ireland and how it can benefit you. Insulation is a material that reduces the amount of heat that is lost or gained through the walls, floors, ceilings, and roofs of a building.

By insulating your home, you can lower your heating and cooling bills, improve your indoor air quality, and reduce your carbon footprint. This blog post will explain what is the most common insulation in Ireland, how it works, its benefits, and its drawbacks, and also give you some tips on how to choose the right insulation for your home.

So, without any further ado, let's get started.

What is the Most Common Insulation in Ireland?

According to the latest statistics from the Sustainable Energy Authority of Ireland (SEAI), the most common type of insulation in Ireland is spray foam insulation.  Spray foam insulation is a type of insulation that is applied by spraying a liquid mixture of chemicals that expands and hardens into foam.

The foam fills up the gaps and cracks in the walls, floors, ceilings, and roofs, creating a continuous and airtight barrier that prevents heat loss and air infiltration. Spray foam insulation can be divided into two main categories: open-cell and closed-cell.

  • Open-cell spray foam is softer and more flexible than closed-cell spray foam, and it has a lower density and a lower R-value (a measure of thermal resistance). It is more likely to cause moisture and sound transmission. 
  • Closed-cell spray foam is denser and more rigid than open-cell spray foam, and it has a higher R-value and a higher strength. It is more resistant to moisture, sound, and fire.

What are the Benefits of Spray Foam Insulation?

Spray foam insulation has many benefits that make it the most common type of insulation in Ireland. Some of these benefits include:

Energy efficiency

Spray foam insulation can reduce your heating and cooling bills by up to 50%, as it prevents heat loss and air leakage and creates a more consistent indoor temperature. It can also improve the performance of your HVAC system, as it reduces the load and wear and tear on your equipment.


This insulation can make your home more comfortable, as it eliminates cold spots, drafts, and temperature fluctuations. Spray foam insulation can also reduce noise pollution, as it blocks the transmission of sound waves through the walls and ceilings.


It can improve your indoor air quality, as it prevents the entry of allergens, pollutants, and pests into your home. It can also prevent the growth of mould and mildew, as it reduces the moisture and condensation in your home.


This can last for the lifetime of your home, as it does not sag, settle, or deteriorate over time. Spray foam insulation can also strengthen the structure of your home, as it adds rigidity and stability to your walls and roofs.


It reduces your environmental impact as it lowers your energy consumption and greenhouse gas emissions. Spray foam insulation can also be made from renewable or recycled materials, and it does not contain any harmful substances like formaldehyde or ozone-depleting gases.

What are the Drawbacks of Spray Foam Insulation?

Spray foam insulation is not without its drawbacks. Some of the drawbacks are:


Spray foam insulation is one of the most expensive types of insulation, as it requires specialised equipment and trained installers. The cost of spray foam insulation can vary depending on the type, the thickness, and the area of application, but it can range from €20 to €70 per square metre.


This is one of the most complex types of insulation, as it involves spraying chemicals that can be harmful to your health and the environment. The installation of spray foam insulation can also be messy, as it requires clearing the space, covering the furniture, and ventilating the area. The installation of spray foam insulation can also take longer than other types of insulation, as it requires curing time and quality checks.


This is not compatible with all types of buildings, as it can cause problems with the ventilation, the drainage, and the electrical systems. Spray foam insulation can also affect the appearance and value of your home, as it can alter the shape and colour of your walls and roofs.

How Do You Choose the Right Insulation for Your Home?

Spray foam insulation might be the most common insulation in Ireland, but it might not be the best option for your home. To choose the right insulation for your home, you need to consider several factors, such as:

The climate of your location

They have different R-values, which indicate how well they resist heat flow. The higher the R-value, the better the insulation. The R-value that you need depends on the climate of your location, as colder climates require higher R-values than warmer climates. For example, the recommended R-value for attic insulation in Ireland is between 10 and 14, while the recommended R-value for wall insulation is between 4 and 6.

The structure of your home

Different types of insulation have different forms, such as batts, rolls, loose-fill, rigid boards, or spray foam. The form that you need depends on the structure of your home, as different forms are suitable for different spaces and surfaces. For example, batts and rolls are ideal for flat and regular spaces, such as attics and floors, while loose-fill and spray foam are ideal for irregular and hard-to-reach spaces, such as walls and ceilings.

The budget of your home

They have different costs, which include the material, the labour, and the maintenance costs. The cost that you can afford depends on the budget of your home as well as the expected return on investment. For example, spray foam insulation is more expensive than other types of insulation, but it can also save you more money in the long run, as it reduces your energy bills and increases your home value.


To sum up, are you considering a home makeover to enhance warmth, comfort, and energy efficiency? Spray foam insulation can significantly impact your home's warmth, comfort, and energy efficiency. However, it's important to weigh the initial investment against the long-term benefits, considering factors such as climate, home structure, and budget, to make an informed decision that suits your specific needs.

How to clone into other project?

  • Press "Ctrl + E" or "Cmd + E" in the Designer and enable "Select on-page element".

  • Search for the class named, "Cloneable Area".

  • Copy the element inside this container to your own project.

  • Rename the classes accordingly if they are clashing with your project.

  • Ensure custom code from the in-page setting has been copied into your project as well (if there's any).

  • 'Page Trigger' interaction can't be copied directly. You can only clone the whole project, or rebuild it.
    A simple trick to copy the 'Page Trigger' interaction into another project is as below:

    1. Create a dummy element.
    2. Apply any type of 'Element trigger' into the dummy element and select the 'Page Trigger' animation.
    3. Copy the dummy element with the animations applied into your new project.
    4. The animation should have been copied into your project and you can reapply the 'Page Trigger' animation into your project.

  • If you have further inquiry or need assistance, feel free to contact us.

  • Lastly, please do not copy this project and claim it as your own. We wish to continue sharing and giving to the community. In order to do so, we will need your cooperation and full support. Thank you very much,
