Internal Wall Insulation for Dún Laoghaire homes

Internal insulation is the main way to insulate the walls of Dún Laoghaire's Victorian and Edwardian homes, because so many sit in conservation areas or are protected structures. These solid brick and stone walls are exposed to salt-laden coastal air and need to stay breathable, so we test moisture before choosing a system and favour vapour-open materials. Shutters, cornices and window reveals are worked around carefully, and rooms are done one at a time so the house stays usable.

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 internal wall insulation works

Internal wall insulation lines the inside face of external walls with insulated boards or a stud and insulation system, then replasters. It suits homes where the exterior has to stay as it is: red-brick period terraces, protected structures, Architectural Conservation Areas, or a single elevation that cannot be wrapped externally.

Is there a grant for internal wall insulation in Dún Laoghaire?

SEAI individual grants for internal wall insulation (dry-lining) are €4,500 for a detached house, €3,500 for a semi-detached or end-of-terrace, €2,000 for a mid-terrace and €1,500 for an apartment, for homes built and occupied before 2011. 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.

How much room space does internal insulation take?

Usually 60mm to 100mm off each external wall, depending on the system. On a typical room that is a small loss of floor area for a large gain in comfort.

Is internal insulation safe for solid brick walls?

It is when the system suits the wall. Solid brick needs moisture to be able to move, so we choose between breathable and vapour-closed systems after assessing the wall and detail the junctions carefully.

Can I live in the house during the work?

Yes, we work room by room so the rest of the house stays usable. Each room is out of use for one to two days.
