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.

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.
