Internal Wall Insulation for Dundrum homes
Pre-war homes near Dundrum village and in Churchtown have solid brick walls, and where they sit in the village conservation area the front elevation is best left untouched. Internal insulation is how those walls get insulated. Solid brick needs to dry out to the inside as well as the outside, so we test the walls and usually choose a breathable system such as wood fibre or insulated lime, detailing window reveals and the floor junction carefully. In the Ballinteer and Sweetmount estates, internal insulation is mainly used room by room during renovations.
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 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.

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.
