Frequently Asked Questions
How much does fibreglass attic insulation cost?
What is fibreglass attic insulation?
Fibreglass attic insulation is made from fine strands of recycled glass spun into a wool-like material. It is installed in attics to reduce heat loss, improve indoor comfort, and lower energy bills.
How thick should fibreglass insulation be in the attic?
The current recommended depth in Ireland is 300mm. This is usually applied in two layers: one between the joists and another cross-layered on top to minimise heat loss through thermal bridging.
Will I still be able to use my attic for storage?
Yes. OSBER can raise the floor joists in your attic to allow for the full 300mm insulation depth while preserving storage space above the insulation layer.
Is fibreglass insulation safe to use around electrical wiring?
Yes, it is safe when installed correctly. Our team ensures that all insulation is fitted according to safety regulations and that electrical components are not compromised.
Does OSBER help with SEAI grant applications?
Absolutely. We provide full support to help you apply for SEAI grants, making the process easier and more accessible for homeowners.
How long does attic insulation installation take?
Most installations can be completed in half a day, depending on the size and layout of the attic.
Do I need to remove old insulation before installing new fibreglass insulation?
In some cases, yes. If the existing insulation is damaged, mouldy, or compressed, it may need to be removed. Our team will assess this during your free home survey.
