Floor Insulation in Dún Laoghaire
Insulating suspended timber and solid ground floors to stop cold floors and draughts at skirting level. Covering East Pier, Sandycove, Glasthule and the surrounding area.
Floor Insulation for Dún Laoghaire homes
Dún Laoghaire period homes usually have suspended timber floors, sometimes over damp, poorly ventilated voids near the coast. We check sub-floor ventilation and timber condition first, then insulate between joists with an airtightness layer and seal the skirting. It is an upgrade that changes nothing visible, which suits conservation areas.
How homes in Dún Laoghaire lose heat
Period homes here combine solid brick or stone walls, high ceilings, large sash windows and suspended floors, which commonly puts them at E to G. Salt-laden wind off the sea drives draughts and dampness into older walls, so moisture-safe insulation choices matter more than usual.
Typical housing: Victorian and Edwardian terraces and semis between the seafront and Glasthule, period terraces around Sandycove, and newer apartments near the East Pier.
Planning: Large parts of the town are Architectural Conservation Areas with many protected structures, so internal insulation and careful draught-proofing are the usual tools.
How floor insulation works
Ground floors lose heat into the ground and, in older homes, let in a surprising amount of cold air. Period houses with suspended timber floors are often draughty because air moves freely through the ventilated void below and up through gaps between boards and at the skirting.

Is there a grant for floor insulation in Dún Laoghaire?
SEAI grant-aids floor insulation at €3,500 when it is part of a home upgrade through an SEAI One Stop Shop. It is not available as an individual grant. Grant amounts are set nationally by SEAI and change from time to time, so check seai.ie before applying. We confirm what your home is likely to qualify for during the survey.
Can you insulate a suspended timber floor without removing it?
In some homes the floor can be insulated from below through an accessible void, but most Dublin period floors need boards lifted. We assess access before recommending a method.
Will floor insulation stop draughts?
Yes. Much of the cold felt in period homes comes from air moving up through boards and at the skirting. Sealing those gaps is part of the job.
Is there a grant for floor insulation?
Floor insulation is grant-aided at €3,500 through the SEAI One Stop Shop route, not as an individual grant. We can advise whether that route suits your upgrade.
