External insulation


In essence, external insulation is applying insulation panels to the exterior of your home, followed by a protective mesh, a basecoat and then two coats of special render.


External insulation is more expensive than internal insulation since it must be applied with a durable finish to withstand the extremes of Irish weather. However, it is more effective at reducing heat loss since it wraps around the entire wall of your building.


This method also allows you to apply very thick layers of insulation to the walls’ external surface meaning that it is a very effective way of reducing heat loss from your home. What’s more, in older houses it can also give an attractive facelift.
