Your attic is one of the main sources of heat loss in a home—up to 30% of your heat can escape through an uninsulated or poorly insulated roof. By upgrading your attic insulation, you can:
Reduce heating bills by up to 30%
Improve your BER rating and increase your property value
Make your home warmer, quieter, and more comfortable
Help the environment by reducing energy consumption
Insulation is one of the most cost-effective ways to improve energy efficiency and comfort in your home.
We work with homeowners across Cork City and County, providing premium insulation materials and professional installation that delivers long-term results. Whether you’re upgrading your home’s insulation or insulating a new build, we’re here to help.
If your energy bills are unusually high during winter, your home feels cold even with the heating on, or there are uneven temperatures between floors, your attic insulation may need replacing. Other signs include draughts coming from the attic, visible gaps or compressed insulation, and rooms overheating in summer. These issues indicate that heat is escaping through your roof, costing you money and reducing comfort.
