External Wall Insulation (EWI) is one of the most effective ways to improve the energy efficiency, comfort, and appearance of your home. The system involves fixing high-performance insulation boards to the exterior walls of a property and finishing them with a reinforced basecoat and decorative render. This creates a continuous insulated layer around the building, significantly reducing heat loss through the walls.
Many older homes in Ireland were built with little or no wall insulation, which means heat escapes easily. External wall insulation solves this problem by wrapping the building in a high-performance thermal layer, helping homeowners reduce energy consumption while improving indoor comfort.
External insulation dramatically reduces heat loss through external walls, helping your home retain heat more effectively and improving its overall energy rating.
By reducing heat loss, homeowners can use less energy to heat their homes. This can lead to noticeable savings on heating bills over time.
External wall insulation helps eliminate cold spots and draughts, creating a more consistent indoor temperature and a more comfortable living environment throughout the year.
As part of the installation, your home receives a new high-quality render finish. This can completely transform the appearance of older properties while protecting the exterior walls.
Because the walls remain warmer, there is less opportunity for condensation to form internally. This can help reduce the risk of mould growth and damp issues.
External insulation adds an additional protective layer to your property, helping to shield the original structure from weather exposure and temperature fluctuations.
Improving a home’s energy efficiency and appearance can make it more attractive to buyers and increase its long-term property value.
External wall insulation is a long-term investment in energy efficiency, comfort, and durability, while also giving your home a fresh, modern finish. With rising energy costs and an increasing focus on sustainable housing, more homeowners across Ireland are choosing external insulation as a practical way to upgrade their homes.
When installed correctly using a complete certified insulation system, you can significantly improve your home’s energy performance, reduce heat loss, and create a more comfortable living environment all year round.
As an added benefit, external insulation also transforms the exterior of your home. You can choose from a wide range of finishes to suit your style, including:
Another major advantage is how low maintenance it is. Unlike traditional finishes, there is no need for regular repainting. With only minimal upkeep — such as the occasional light power wash — your home’s exterior can stay looking clean and fresh for years to come.
A high-quality finish, built to last — improving how your home performs, feels, and looks for years to come.
Choosing the right contractor is just as important as choosing the right insulation system. Our team specialises in high-quality external wall insulation installations, with a strong focus on precision, durability, and professional workmanship.
We exclusively install the complete Baumit External Wall Insulation system, ensuring that every component of the installation works together as a fully certified system. Unlike contractors who mix and match products from different manufacturers, we follow the correct system specification to ensure long-term performance and reliability.
When you choose us, you benefit from:
Our goal is simple — to deliver an external insulation system that improves energy efficiency, enhances your home, and stands the test of time.
We follow a detailed installation process to ensure every project meets the highest standards of quality and performance.
We begin by assessing the property and measuring external walls to determine the most suitable insulation solution.
The walls are prepared and cleaned to ensure the insulation boards are securely fixed and the system performs correctly.
High-performance insulation boards are mechanically fixed and bonded to the exterior walls to create the thermal layer.
A reinforced basecoat with fibreglass mesh is applied to strengthen the system and prevent cracking.
The system is completed with a high-quality decorative silicone render that protects the insulation while enhancing the appearance of the home.
Homeowners in Ireland may be eligible for SEAI (Sustainable Energy Authority of Ireland) grants when upgrading their home with external wall insulation. These grants are designed to support energy efficiency improvements and help reduce heating costs.
Grant amounts vary depending on the type and size of the property, but typical SEAI grant support currently includes:
These grants can cover a significant portion of the installation cost, making external wall insulation one of the most cost-effective upgrades for improving your home’s energy efficiency.
Our team can guide you through the process and ensure the system installed meets the required standards for grant eligibility.
Grant values are subject to change. Please refer to SEAI for the most up-to-date information.
Homes with little or no insulation often have cold external walls that make rooms feel uncomfortable, even when the heating is on. External wall insulation helps retain heat within the building, making rooms warmer and more comfortable throughout the year.
Poor insulation allows heat to escape quickly, meaning heating systems need to work harder to maintain a comfortable temperature. By significantly reducing heat loss through the walls, external insulation can help lower energy consumption and reduce heating costs.
Cold walls can cause condensation to form inside the home, which can lead to damp patches and mould growth. External insulation helps keep walls warmer, reducing condensation and improving overall indoor air quality.
Over time, exterior walls can become weathered, cracked, or discoloured. External wall insulation not only improves the thermal performance of the home but also provides a brand-new decorative render finish, giving the property a fresh and modern appearance.
Homes with little insulation often have lower BER (Building Energy Rating) scores. Installing external insulation can significantly improve a property’s energy rating, which is beneficial for both energy efficiency and future property value.
In poorly insulated homes, some rooms can feel much colder than others. External insulation helps create a more consistent temperature throughout the house by improving the overall thermal performance of the building.
