External Wall Insulation for Dundrum homes

In Dundrum, external insulation is most useful on the Ballinteer and Sweetmount estate homes where cavity fill is not possible or not enough. The period homes near the village and Churchtown are more often in conservation areas, where front elevations are kept as they are and rear walls or gables may be wrapped externally instead. We check planning and wall condition at survey stage.

How homes in Dundrum lose heat

The two stocks lose heat differently. Pre-war homes have solid or early cavity walls, suspended timber floors and draughty sash windows, often rating E or worse. The estates have cavity walls that were frequently built empty, original 100mm attic insulation and leaky attic hatches, usually landing around C3 to D2.

Typical housing: Period red-bricks and pre-war semis near the village and Churchtown, with 1960s to 1980s estate housing across Ballinteer, Wesley and Sweetmount.

Planning: Parts of Dundrum village sit within an Architectural Conservation Area, which can rule out external insulation on front elevations.

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.
