Floor Insulation in Dublin 4
Insulating suspended timber and solid ground floors to stop cold floors and draughts at skirting level. Covering Donnybrook, Sandymount, Ballsbridge and the surrounding area.
Floor Insulation for Dublin 4 homes
Dublin 4's period homes typically have suspended timber floors at hall and ground level, sometimes over basements. We insulate between joists, add an airtightness layer and seal the perimeter while protecting original boards and keeping sub-floor ventilation clear. It is a powerful upgrade in protected houses where the outside cannot change.
How homes in Dublin 4 lose heat
Large period homes have high ceilings, big sash windows, solid walls and suspended floors, so their heating demand is high and BERs of E to G are common despite good maintenance. Sandymount homes near the strand are also exposed to sea wind. Modern apartments mainly benefit from airtightness and ventilation checks.
Typical housing: Victorian and Edwardian red-brick terraces in Donnybrook, Sandymount and Sydney Parade, larger period semis and detached homes on Ailesbury and Shrewsbury, and modern apartments and townhouses toward the docklands.
Planning: Much of Dublin 4 is within Architectural Conservation Areas, and protected structures are common on Ailesbury, Shrewsbury and Pembroke Road.
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.

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.
