An uninsulated home can lose up to 35% of its heat through the walls so it is easy to see where significant savings on energy bills can be made!

Internal Wall Insulation

Internal Wall Insulation creates an insulation envelope around the home. Because the heat can no longer escape through the walls, it is reflected back into the living areas, creating a constant warm home.

It has various advantages which include improving the air tightness of a home (i.e. elimination of unwanted draughts through the building fabric), as well as substantially increasing the thermal performance of a dwelling.

Internal Wall Insulation

With up to 35% of heat lost through uninsulated walls, internal wall insulation can reduce your heating bills significantly. It can also reduce your carbon footprint by cutting your CO2 emissions by up to 2.5 tonnes per year.

What are the benefits of wall insulation?

  • Dramatic reduction in heat loss

  • Rooms are easier to heat and stay warmer for longer after heating is switched off
  • Eliminates condensation and resulting mould growth
  • Improves your home’s energy rating
  • Gives walls a clean fresh look

Fitzpatrick Insulation recently completed cavity wall and attic insulation work at our home. They did a terrific job – a thorough review of all requirements was agreed beforehand, great attention to detail on the entire project and everything completed to agreed timescales. We believe this was definitely a worthwhile investment and we have already recommended Fitzpatrick Insulation to friends and family. Thanks again for the great job – we are enjoying a warm winter as a result of all your hard work!

The work carried out by Fitzpatrick Insulation (attic and wall insulation) was to a high standard in terms of effectiveness, attention to detail (impossible to see where exterior walls were drilled) and cleanliness. All works carried out were done so with minimum disturbance. I am happy to recommend Fitzpatrick insulation to anyone who is contemplating having similar work carried out.
B Lorimer, Jenkinstown, Co. Kilkenny
Thank you John. You provided exactly what you said you would. House stays warm for much longer after turning off heating, and is surprisingly still warm in the morning without putting on any heating. We are very happy with the installation.
T Roche, Stonyford, Co. Kilkenny
Fantastic professional service provided by a fantastic team. Our home has seen a significant difference since the works were completed to a high quality with little or no mess. Guidance from start to finish by John made the process quick and effortless for us.

Best job we ever got done. Our heating bills have reduced by over 50% and job will pay for itself in a few years. We are sorry we didn’t get it done 20 years ago. House is much more comfortable and stays warmer for much longer.
B O'Connor, Portlaoise, Co Laois
Thanks John. Money well spent. Delighted with your work, our house is much warmer and we have turned down the heating and reduced our cost on oil. You provided excellent service, explained all details of the job, and left the house the way you found it.

Fitzpatrick Insulation installed our Attic Insulation. We found them to be highly efficient and professional and we are delighted with the result. We were having problems with keeping the building warm and that is now rectified. We would be happy to recommend them to anyone.
Hotel Kilkenny, Kilkenny
It was impossible to keep our house warm and with two small children was a huge concern. Our home has been noticeably warmer since (from the very first night onwards. My only regret is that we did not contact you sooner and get this done years ago.
