Why Irish homeowners choose External Wall Insulation

Many Irish homes lose a significant amount of heat through their external walls. Turning the heating up can push energy bills higher, yet rooms may still feel cold, uneven or draughty — particularly in older homes or properties with solid or poorly insulated walls.

External wall insulation helps address this by reducing heat loss at the source. When designed and installed correctly, it helps homes stay warmer for longer, improves overall comfort, and reduces the amount of energy needed to heat the home. It also refreshes and protects the external finish of the property.
