What Is Outside Wall Insulation?

External insulation has the effect of warming the wall, which in turn causes the dew point to migrate outwards, towards the cooler external air, lowering the likelihood of condensation forming on the interior surface. But there is a risk that the dew point will develop between the insulation and the wall, or even within the insulation.

External wall insulation entails attaching a layer of insulating material to the wall and then covering it with a specific form of render (plasterwork) or cladding to keep the cold out. Smooth, textured, painted, tiled, paneled, pebble-dashed, or finished with brick slips are all options for the final finish.
