External Wall Insulation for Stillorgan homes

Many of Stillorgan's post-war houses have solid or hollow-block walls, which makes external insulation the right upgrade. On a detached house the grant is €8,000 and the effect on comfort is large, because all four walls are exposed. Planning is rarely an issue on these estates.

How homes in Stillorgan lose heat

Some of the earlier post-war houses here were built with solid or hollow-block walls rather than cavities, which a quick borescope check confirms. Typical ratings sit around D1 to E1, held back by walls, thin attic insulation and uninsulated floors. Detached homes have four exposed walls, so wall insulation has a large effect.

Typical housing: Post-war and 1960s detached and semi-detached houses on generous plots, laid out in classic mid-century Dublin estates.

Planning: Little conservation constraint on the estates, so external insulation is usually exempted development.

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.

Is there a grant for external wall insulation in Stillorgan?

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.
