Internal Wall Insulation in Sandyford
Insulated dry-lining for homes where the outside cannot change, done with careful vapour and moisture control. Covering Sandyford Hall, Stepaside, Carrickmines and the surrounding area.
Internal Wall Insulation for Sandyford homes
Sandyford's 1970s and 1980s houses are mostly cavity-built, so internal insulation is a targeted tool rather than a whole-house answer. It earns its place in rooms over integral garages, in north-facing bedrooms that stay cold even after a cavity fill, and in rooms already being renovated where the walls are being replastered anyway. Insulated plasterboard on battens, with sockets and radiators moved out, costs a few centimetres per wall and makes those rooms noticeably warmer. We usually recommend it alongside attic and cavity work rather than instead of it.
How homes in Sandyford lose heat
The older estates were built with cavity walls that were often left empty or partly filled, thin attic insulation and early double glazing, which typically leaves them in the C to D BER range. The newer Stepaside and Carrickmines homes perform better but often have airtightness gaps around downlights and attic hatches. Being on the foothills of the Dublin Mountains, homes here also sit in a slightly colder, windier spot than the city.
Typical housing: 1970s and 1980s detached and semi-detached homes around Blackthorn and Sandyford Hall, with newer estates running up into Stepaside and Carrickmines.
Planning: Little conservation constraint on the estate housing, so external wall insulation is usually exempted development where it is needed.
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.

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.
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.
