External Wall Insulation for Dún Laoghaire homes
With so much of Dún Laoghaire in conservation areas and many protected structures, external insulation is used selectively, typically on rear returns, gables and newer extensions where the change is not visible from the street. Coastal exposure means we specify systems and details for wind-driven rain and salt air.
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 external wall insulation works
External wall insulation fixes insulation boards to the outside face of the walls and finishes them with a reinforced render system. Because the insulation is continuous around the house, it deals with the cold bridges at floors and party walls that internal insulation struggles with, and the work happens outside so you can stay living in the house.

We confirm what your home is likely to qualify for during the survey.
Does external wall insulation need planning permission?
Most external insulation is exempted development, but protected structures, Architectural Conservation Areas and changes that affect the look of a terrace can need planning. We check this at survey stage.
Will external insulation stop damp?
It keeps the wall warmer, which reduces condensation and mould on internal surfaces. Rising or penetrating damp has to be dealt with first, which is why we test the walls before specifying a system.
How long does an external wall insulation job take?
Five to ten working days for a typical semi-detached house, depending on weather. Render cannot be applied in rain or frost, so we plan around the forecast.
