Insulation Services
Warmer homes. Lower bills. Trusted insulation solutions across Ireland.
Insulation first — everything else works better after
The foundation of every energy upgrade
Before heat pumps, solar or heating controls — insulation is step one. We offer SEAI-approved insulation services for homes of all ages, wall types and budgets. Whether you're doing a full retrofit or just tackling a cold attic, we’ll help you build a warmer, more efficient home.
Our core insulation services
- Attic Insulation — the simplest way to stop heat rising and escaping
- Cavity Wall Insulation — for homes with hollow block or unfilled cavities
- External Wall Insulation — wrap-around insulation for solid wall homes
- Internal Wall Insulation — drylining for properties where external insulation isn’t an option
- Spray Foam Insulation — air-tight, high-performance solution for attics, roofs & commercial projects
We’ll confirm what type of insulation suits your property best during your free survey.

Why insulation matters
More than just comfort — insulation pays for itself
- Reduces heat loss by up to 30–50%
- Improves your Building Energy Rating (BER)
- Lowers your heating bills by hundreds every year
- Supports eligibility for grants and deep retrofit schemes
Insulation also protects your structure from condensation and improves indoor air quality when combined with proper ventilation.

Where we work
We insulate homes in all 32 counties. Whether you’re in a rural cottage, an estate semi, or a mid-terrace home in the city, we have a solution that fits — and a team that covers your area. See coverage.
Planning a full retrofit?
We’re insulation-first — but we also install heating controls, solar PV and heat pumps where needed. If you’re applying for a deep retrofit or One Stop Shop grant, we’ll design the insulation portion to meet SEAI standards and help with compliance.

Quick answers
Which insulation type is best?
That depends on your wall type, roof space, and budget. We’ll assess your home and recommend what gives the best return for comfort and energy savings.
Is grant funding available?
Yes — SEAI offers grants for attic, cavity, internal and external wall insulation. We’ll handle the paperwork if you qualify.
Do you remove old or failed insulation?
Yes — we can extract old cavity insulation or remove damaged attic layers before re-insulating.
Can I insulate one part of the home first?
Yes — we can phase insulation upgrades room-by-room or area-by-area. Many clients start with the attic or cold walls first.
Will insulation really make a difference?
Yes — you’ll feel it in comfort and see it in lower energy bills. Most insulation upgrades pay for themselves in just a few years.
