How Does External Insulation Work? A Smart Solution for Dublin Homes

Are you trying to find a successful method to improve your home’s energy efficiency? If you are in Dublin, where the weather is notoriously hit-or-miss, external insulation is a transformative solution. So, whether you are looking to insulate your home with the best of our eco-friendly products or you want to learn more about what we do at Greenenergyhomes, we are here to share our knowledge and make your home warmer, greener, and more cost-efficient. But what is external insulation, and why would you want it in your home? Let’s break it down.
What Is External Insulation?
External insulation, often called external wall insulation (EWI), consists of placing a layer of insulation over the outer walls of your property before adding protective render or cladding. Using this design process, the thermal performance is greatly increased, avoiding great heat loss from the walls. To put it simply, it effectively dresses your home in a thermal jacket, keeping you snug and warm in winters and helping you have a cooler room temperature in summers.
How Does External Insulation Work?
The external insulation process involves three main steps:
- Preparation: the outer surfaces are cleaned and prepared for the insulation application.
- Insulation: High-performance insulation boards (expanded polystyrene, mineral wool or phenolic foam) are adhered and fixed mechanically to the outside of the walls.
- Protective Coating: Also, a weather-resistant render or cladding is applied on top of the insulation to seal and protect it from the outside environment.
This process forms a thermal buffer, which minimizes heat loss and dramatically increases the energy efficiency of your home.
The Benefits of External Insulation for Dublin Homes
1. Significant Cost Savings
As energy prices rise, homeowners want to keep heating costs as low as possible. You’ll also use up to 40% less heat with external insulation, as your home stores warmth for longer without the need for so much energy to reach a comfortable temperature. That means lower heating bills and savings over the long run.
2. Enhanced Energy Efficiency
This will improve your home’s BER (building energy rating), making it more energy-efficient and eco-friendly. A higher BER rating can also boost your property’s value and appeal to potential buyers.
3. Improved Comfort All Year Round
Dublin’s climate can be cool and wet, so proper insulation is key. External insulation maintains your home’s temperature in the winter and summer, keeping you comfortable year-round without cooking and without relying on excessive heating or air conditioning.
4. Reduced Carbon Footprint
External insulation helps reduce your home’s carbon footprint by minimizing energy consumption. This eco-friendly solution also promotes sustainability efforts and contributes to combating climate change.
5. Enhanced Property Appearance & Protection
This improvement also goes beyond insulation and gives your home a clean, stylish aesthetic while keeping exterior walls protected from the elements. It leaves behind a durable protective coating that makes your structure impervious to dampness, cracks and structural damage, extending its longevity.
