Insulation is the single most cost-effective energy upgrade for most Irish homes. Properly insulating your attic, walls, and floors can cut heat loss by 40–60% and drop your heating bills by €300–€600 per year.
CEL Energy Ltd provides professional insulation installation across Cork City, suburbs, and county. We handle the SEAI grant paperwork — you just pay the difference.
From attic insulation to wall and floor upgrades, here's what each solution costs, what SEAI grants are available, and which properties benefit most.
Blown-in or boards installed in your attic space. Reduces roof heat loss by up to 25%.
Insulation injected into the cavity between external brick and internal walls.
Insulated boards fixed to exterior walls, finished with render. Biggest impact on BER rating.
Insulated plasterboard fitted to interior walls. Alternative when external isn't feasible.
Insulation below ground floors or between suspended floors and joists.
All insulation types qualify for SEAI One Stop Shop grants. We handle the application paperwork.
