What Is Fibreglass Insulation?
Fibreglass insulation is traditionally one of the most widely used and cost-effective insulation solutions in Ireland. It is made from fine glass fibres, formed into rolls or batts, and installed in attics/lofts, walls, and floors to slow down heat loss.
While modern solutions such as spray foam or cellulose insulation are more widely adopted today, fibreglass insulation is still a popular choice for many. At Lovinsulation, we only use high-quality fibreglass products that are safe, long-lasting, and installed by experienced professionals.
Where It Works Best:
- Attics & Loft Spaces – The most common and cost-effective use.
- Between Floor Joists – Improves sound-proofing between levels.
- Walls (in certain applications) – Can be used in cavity wall or timber frame construction.

Before choosing LoveInsulation, we had assessments and quotes from at least four other companies. Not only were Yann and his team the most competitive, but they were also the only ones who went beyond a “one-size-fits-all” solution. Their attention to detail and genuine consideration of the house’s design really stood out.
The installation itself was carried out quickly, efficiently, and with great care. The team put down carpet covers, worked cleanly, and showed real respect for our home. Now, four weeks on, the difference is remarkable—we can already feel the benefits and are looking forward to a much more comfortable winter.
I would highly recommend Yann and the team at LoveInsulation to anyone considering insulation. Professional, thoughtful, and excellent value for money.
they were so professional lovley chap to deal with he was so pleasant thank you again yann best of luck in future 👍

Considerations When Choosing Your Insulation
While fibreglass is a good option for many homes, it’s important to understand its limitations:
It can lose effectiveness if compressed
requires correct installation to maintain loft and wall coverage.
Lower air sealing
unlike spray foam or dense cellulose, fibreglass alone won’t fully prevent air leakage.
Irritation risk
skin and respiratory irritation possible during installation, so always use a certified installer.
Shorter lifespan
typically 15–20 years before performance may degrade.
