Get it right from the start
Insulation decisions at the build stage matter for decades
When building a new home, the right insulation system sets the foundation for long-term comfort and low running costs. Premier Insulations works alongside your builder or architect to ensure SEAI-compliant, NSAI-certified insulation is installed to spec — cleanly, on time, and ready for airtightness testing.
From cavity bead and spray foam to airtightness and attic insulation, we design the right solution for your build, not just the minimum standard.
What we install for new homes
- EPS bonded bead cavity wall insulation — ideal for block-built walls
- Attic insulation — rolled mineral wool or spray foam to specified depth
- Floor insulation — rigid board insulation systems (if requested)
- Spray foam & airtightness — underside of sloped roofs or critical junctions
We coordinate with your build schedule and issue all documentation needed for BER and SEAI compliance.

Quick answers
When should insulation be installed in a new build?
It depends on the system — we’ll coordinate with your builder to hit the right stage.
Do you work with self-builders?
Yes — we regularly work with homeowners directly and can liaise with your architect or trades.
Can I get a grant for new build insulation?
SEAI grants are generally for retrofits, but we’ll confirm what paperwork you need for BER and certification.
Can you quote from plans?
Yes — send your drawings and insulation spec and we’ll prepare a clear proposal.
