External Wall Insulation

Installing external wall insulation is something that is less common than other insulation, but can be incredibly beneficial. Particularly beneficial on older properties where walls are created from more traditional building materials, external wall insulation helps to minimise condensation by reducing the temperature difference between the internal environment and the outer walls by raising the temperature of the wall, helps to dramatically reduce the amount of heat loss occurring through external walls, and overall result in a large decrease in spend on heating by retaining heat within the building.

Another benefit of external wall insulation is that it can often be retrofitted without too much disturbance within the building, and when fitted does not reduce the internal space, which is what may happen if installing internal insulation.

Insulation boards for external wall insulation

Insulation boards are one of the most popular forms of external wall insulation available. One of the reasons for using insulation boards for external wall insulation is that insulation boards can be easily installed on refurbishment projects as well as new builds, with little impact on the building itself or any activities within the building. Additionally, insulation boards are a popular form of external wall insulation because they have high thermal resistance levels whilst remaining relatively thin, minimising any visual impact and ensuring the building thickness isn't affected too much. Insulation boards are also commonly moisture resistant, meaning that weather conditions will have very little effect on the performance of the insulation board.
