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.
Attic insulation works by reducing the rate at which heat escapes through the roof space. The right solution depends on the condition of the existing insulation, the attic structure and how the space is used. An assessment helps establish the current state before work is recommended.
Where a roof leak, water ingress or structural roof issue is also present, this should be assessed and resolved before or alongside insulation work. See Roof Repairs for roof-covering issues.
Attic insulation does not last indefinitely. Older materials can compress, shift or become damp over time, reducing their effectiveness. Common indicators that insulation may need assessment or replacement include persistent cold in upper rooms, high heating costs relative to the property size, visible condensation in the roof space, or insulation material that is visibly damaged, compressed or missing in sections.
An assessment can confirm the current condition and recommend whether topping up, replacing or leaving the existing insulation is the appropriate course.
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.

Attic insulation is typically one of the more straightforward ways to reduce heat loss in an older property. The right approach depends on the attic structure and the condition of any existing insulation. An assessment can confirm whether installation or an upgrade is appropriate.
Yes, in many cases existing insulation can be topped up or partially replaced rather than fully removed. The best approach depends on the type, depth and condition of what is already there. We can advise after assessing the attic.
Describe the property type, whether the attic is currently insulated, the approximate size of the space if known, and any specific concerns, such as cold rooms, condensation or visible damage to existing insulation. Photos of the attic space are also helpful where it is safe to take them.
