Internal Wall Insulation in Dublin

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.

Solid brick and stone walls need care. They manage moisture by letting it move through the wall, and the wrong internal insulation can trap moisture at the cold brick face. We assess the wall, choose between vapour-closed and breathable systems accordingly, and detail the junctions with floors, ceilings and window reveals to limit cold bridging. Skirting, sockets, radiators and coving are removed and refitted as part of the job.

It does take some floor area, typically 60mm to 100mm off each external wall, and rooms are worked on one at a time. It is often done alongside a renovation, when rooms are being replastered anyway.
