External Wall Insulation for Blackrock homes
External insulation in Blackrock is generally used on inland estate homes and on the rear and side walls of period houses. Front elevations in the conservation areas usually stay as they are, with internal insulation used instead. Coastal homes need render and details suited to sea exposure.
How homes in Blackrock lose heat
Period homes along the coast have solid walls, suspended floors and big sash windows facing the sea wind, often rating E to G. The inland estates follow the mid-century pattern of cavity walls built empty or partly filled, with ratings around D.
Typical housing: Victorian and Edwardian seafront terraces, period semis through Booterstown and Monkstown, and mid-century estate housing inland.
Planning: Significant parts of Blackrock, Booterstown and Monkstown are Architectural Conservation Areas with many protected structures.
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.

The whole wall surface must be treated. 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.
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.
