Why start with your attic?
In a home with no attic insulation, roughly a quarter of all heat escapes straight up through the roof. Insulating the attic is the cheapest, fastest and highest-return upgrade you can make — which is exactly why SEAI grants cover such a large share of the cost. If your attic has less than about 300mm of insulation, this is the first job to do.
The right insulation for your attic
Every attic is different, so we specify the material that suits yours best — from mineral wool and fibreglass quilt to sheep’s wool and Kingspan systems. We bring the attic up to the recommended depth, lag the tank and pipes, and ensure ventilation at the eaves so the roof space stays healthy.
- Roll-out and top-up insulation to current recommended depth
- Pipe and water-tank lagging
- Eaves ventilation to prevent condensation
- Optional insulated attic flooring so you can still use the space for storage
Still want to use your attic for storage?
Storing boxes directly on insulation crushes it and reduces its effectiveness. We can install a raised, insulated flooring system that keeps your storage safe and accessible while protecting the full insulation value beneath it.
Attic insulation grants
SEAI grants for attic insulation increased in 2026 and now cover around 80% of the typical cost for many homes, with higher fixed amounts for first-time buyers and qualifying welfare recipients. Your home needs to have been built and occupied before 2011, and the work must be done by an SEAI-registered contractor — which we are. We’ll confirm the current grant for your house type and handle the paperwork. See all SEAI grants.
