Internal Wall Insulation in Rathfarnham
Insulated dry-lining for homes where the outside cannot change, done with careful vapour and moisture control. Covering Rathfarnham village, Nutgrove, Butterfield and the surrounding area.
Internal Wall Insulation for Rathfarnham homes
Internal insulation in Rathfarnham is mainly a solution for the village period homes and pre-war semis near Rathfarnham Castle, where solid walls and conservation context rule out an external wrap. In the Nutgrove and Butterfield estates it is usually reserved for individual rooms, for example a converted garage or a north-facing bedroom being renovated, with cavity fill or external insulation doing the main job on the rest of the house.
How homes in Rathfarnham lose heat
The mid-century estates are the bulk of the work here: cavity walls often built empty, 1970s-era attic insulation and suspended or uninsulated solid floors, usually rating D. The larger detached homes have more external wall area per room, so wall insulation makes a proportionally bigger difference.
Typical housing: Village stock and pre-war semis near Rathfarnham village, mid-century estate housing through Nutgrove and Butterfield, and larger detached homes toward Knocklyon and Templeogue.
Planning: The village core has conservation context; estate housing generally allows external insulation as exempted development.
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.
