External Wall Insulation in Dublin

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.

It is the main upgrade for solid-wall and hollow-block homes that cannot take a cavity fill. The quality is in the detailing: extending window sills, insulating reveals, sealing around pipes and vents, terminating correctly at the eaves and the ground, and keeping the system clear of damp. We install Baumit ETICS systems under NSAI Agrément certification, which is what SEAI grant work requires.

EWI changes the look of a house, so the finish is chosen with you, from smooth or textured render to brick-effect slips. Homes in conservation areas or protected structures may need planning, and front elevations of period terraces are often better suited to internal insulation.
