Energy Efficiency 101: Cost of New Attic Insulation in Ireland Vs. Replacing
Ensuring your home is well-insulated is crucial for energy efficiency and comfort, especially in Ireland, where the climate can be damp and chilly. If you’re considering attic insulation, you might wonder whether to apply new insulation over existing materials or replace the old insulation entirely. In this article, we’ll explore the costs and considerations of both options to help you make an informed decision.
Cost of New Attic Insulation in Ireland Vs Replacing Existing Insulation
Why Insulation Matters
Before diving into costs, it’s essential to understand why proper attic insulation is so important. Good insulation:
- Reduces Energy Bills: Proper insulation keeps heat in during winter and out during summer, leading to significant energy savings.
- Improves Comfort: A well-insulated home maintains a consistent temperature, enhancing comfort.
- Protects Your Home: Insulation helps prevent issues like dampness and mold, which can cause structural damage.
As heat rises, up to 30% of your home’s heat can be lost through your roof. Insulating your attic space reduces heat loss by keeping the heat in the rooms below the ceiling.

Costs
The cost of attic insulation for new installation over existing insulation in Ireland can vary based on the type of insulation and the size of your attic. On average:
- Materials: Insulation materials (such as fiberglass, rock wool, or spray foam) can range from €10 to €30 per square meter.
- Labour: Professional installation costs can range from €20 to €50 per hour. However, if you’re handy, this might be a viable DIY project.
- Additional Costs: There might be extra costs for ventilation improvements or minor repairs.
Potential Issues
- Reduced Effectiveness: If the existing insulation is damp, damaged, or infested with pests, simply adding new insulation on top may not be effective.
- Weight and Compression: Adding new insulation on top of old can compress the existing insulation, reducing its effectiveness.

Replacing Existing Insulation
Benefits
- Maximised Efficiency: Removing old, ineffective insulation ensures that your new insulation works at its best.
- Addressing Issues: This approach allows you to address any underlying issues, such as moisture problems, mould, or pests.
- Improved Air Quality: Old insulation can harbor dust, allergens, and contaminants. Replacing it can improve indoor air quality.
Costs
The cost of replacing existing insulation is typically higher due to the added steps of removal and disposal. On average:
- Removal and Disposal: Removing old insulation can cost between €10 to €20 per square meter, including disposal fees.
- Materials: As with new applications, insulation materials cost between €10 to €30 per square meter.
- Labour: Professional installation costs remain the same, ranging from €20 to €50 per hour. Given the added removal process, expect higher labour costs.

Comparing the Costs: A Real-Life Example
To put these costs into perspective, let’s consider an average attic size of 50 square meters.
Applying New Insulation Over Existing Insulation
- Materials: 50 sqm x €20/sqm = €1,000
- Labour: 10 hours x €30/hour = €300
- Total Cost: Approximately €1,300
Replacing Existing Insulation
- Removal and Disposal: 50 sqm x €15/sqm = €750
- Materials: 50 sqm x €20/sqm = €1,000
- Labour: 20 hours x €30/hour = €600
- Total Cost: Approximately €2,350
Making the Decision
When deciding between applying new insulation over existing insulation or replacing it entirely, consider the following factors:
- Condition of Existing Insulation: If it’s in good condition, adding a new layer might suffice. If it’s damaged or contaminated, replacement is better.
- Budget: Replacing insulation is more expensive upfront but may offer better long-term savings and efficiency.
- Long-Term Goals: Consider how long you plan to stay in your home and your long-term energy efficiency goals.
Both applying new insulation over existing insulation and replacing it entirely have their pros and cons. While adding new insulation can be cost-effective and quick, replacing old insulation ensures maximum efficiency and addresses potential underlying issues.
Evaluate the condition of your current insulation, your budget, and your long-term goals to make the best decision for your home. By investing in proper insulation, you can enjoy a more comfortable, energy-efficient home in Ireland’s variable climate.
