Keep the Heat In — Professional Attic Insulation Supply & Installation
A poorly insulated attic is one of the biggest sources of heat loss in any Irish home. Up to 25% of your home's heat can escape straight through the roof, driving up your energy bills and making rooms harder to keep warm. Topping up your attic insulation is one of the most effective improvements you can make — and with professional installation included, it couldn't be easier.
What's Included
This product covers the full supply and professional installation of 400 sq ft (37 m²) of Earthwool Top-Up Attic Insulation. Simply choose the thickness that suits your home, and our team will take care of the rest.
Choosing the Right Thickness
150mm Ideal if your attic already has some insulation in place. A 150mm top-up brings your attic up to a more effective level of thermal performance and is a great option for homes that were insulated some years ago but no longer meet current standards.
250mm The better choice for older homes with little or no existing insulation, or for homeowners who want to maximise thermal performance. A 250mm layer delivers excellent heat retention and year-round comfort.
